- Today, one out of three people don’t have access to safe drinking water. And that’s the result of many things, but one of them is that 96.5% of that water is found in our oceans. It’s saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than one percent of it is available to us. So why can’t we just take all that seawater, filter out the salt, and have a nearly unlimited supply of clean, drinkable water?

Can Sea Water Desalination Save The World?
Serving on a nuclear submarine years ago, potable water production was one of my many responsibilities. With essentially limitless energy at our disposal, we operated distillation facilities capable of producing sufficient fresh water for drinking, cooking, washing and laundry, as well as water for batteries and make-up water for the propulsion plant.
After the Navy, I worked on some of the first reverse osmosis membranes, as well as RO plant design, construction and operation.
With that as a background, it astounds me that, as a country, we throw potable water on the ground (a.k.a. watering the lawn). This practice would be unheard of for a large percentage of the world's population. Conservation is key. From non-water intensive lawn/landscapes and agricultural techniques, to vegetarian/vegan diets, to efficient or composting toilets, we need to be better stewards of our natural resources.
Important developments that this piece missed include:
• Atmospheric water generation
• Grey water recycling
• Waste water purification (RO without brine discharge)
• Rain water and run-off reclamation (RO without brine discharge)
As with climate change, there is no silver bullet. Only silver buckshot.
Also, with respect to brine discharge, natural evaporation would partially eliminate other salt mining/production requirements.
John Coloe ..so what your saying is if people were responsible and conscious of what we were doing, we wouldnt need to desal ocean water?
I don't understand your point here - Not throwing water onto a lawn doesn't magically teleport it to Africa?
@@muzic4lyfe2005 You probably could do it without desalination plants if all the sacrifices he mentioned happen. Which they wont. People wont stop watering their gardens. Also Brine compared to the sheer quantity of ocean water there is, is not a problem if they simply disperse the stuff over a wider area.
I wouldn't put any hope in atmospheric water generation though. If by that you mean dehumidifiers. It's by far most ineffective and energy intensive way to produce water. And efficiency is further reduced when it's used in places that actually need the water, due to lower humidity.
Theres no money in that.
look at the bright side we are never going to run out of salt
We already have a great abundant desalinization process! It's called rain! Stop channeling it as fast as possible right back into the ocean!!! The bigger the river the bigger the drought!!! Concrete world can't absorb water into the earth! Stop flowing the water into the ocean!!!
@@AquarianSoulTimeTraveler i dont no what your talking about but ok .if it makes sense to you
Samoht Sirood Well, rain still needs to be filtered due to air pollution. That aside, rain collection isn’t always a feasible option because many people, me, live in a desert.
Jaxon W the ya re trying to say instead of directing it let the ground filter it then we drink it WATER GOES UNDERGROUND not supposed to go into a concrete canal then back into the ocean plus EVERY single thing ends up in the ocean either wsy
RedSpartan177 That’s how we’ve been doing it for years. Pump the water out of the ground. It’s called a well.
In Western Australia Practically all the energy for our Desalination Plants is provided by Large Wind Turbines which are far from the city in sparsely populated areas The windiest time is in our dry summer which is also when we need the most Water
As I say, "We don't have a water shortage. We will never have water shortage. We will only struggle with how we clean it."
Get rid of the water companies that steal water. They take regular tap water and then put their label on it. For instances like Arrow head and Crystal Geyser. Both of those companies get their water from California. California is in a big drought as we all know. How about those two big companies stop taking tap water? I bet it would help California out and the rest of the states as well. Essentially they steal water, steal millions upon millions gallons of water.
Maybe if Coca Cola and Pepsi stopped using so much of it we would have a chance
@@jenivettebigham7060 i don't think that's the issue
@@jenivettebigham7060 AND also bottle water companies
We’re not struggling with how we clean it we control access via information. The problem is that only a select mass of people have access to this knowledge. It is a privilege that shouldn’t be. And on top of that materials are also controlled through monopolies. You know the 1% of people who control 99% of the planet.
This problem should have been addressed 30 to 40 years ago. Here on the west coast, the people are more worried about their property values than clean drinking water. I remember when the San Diego plant was being built, the people in the next county {Orange County} were so glad it wasn't being built in their county. Now they have a plant going up and they are not very happy with it. Personally, I feel that California could use about 8 to 10 plants along the coast.
Do your homework. Reverse osmosis desalination damages the ecology of our ocean.
Maybe so many people should not live in the desert. No hate but let’s be honest you know and I know it’s crazy town. I know the weather is wonderful and all but it was never meant for millions of people to live there. Again I I Ike the state it’s just way to crowded.
When San Onofre NPP was operating , the waste heat was sufficient to run either a thermal multistage flash desalination, or its improvement, the mult effect thermal one. Other variations are the vapor compression thermo electric unit, very compact, but relies on the availability of inexpensive night time power, then available from the 2 NPU's.
on all thermal units scaling is a problem, which can be controlled by addition of phosphoric acid (also an ingredient in CoCa Cola)
Then what is your plan?
@@OCFilmFan
How so?
I'm not a chemist, but am almost certain that more focused research about desalination and filtering would have profitable results. Treating these activities as infrastructure would pay off.
I have pitched this idea for years. The technology is used in desert countries and cruise and naval ships. Coastal states could do it and use the process to clean the water enough to supplement well drinking water, pump it into holding ponds to seep into ground water. Create marshes for nature to clean the rest of it up and use it for agriculture. You can build power boiler plants and use the water also for steam with heat driven by many sources. Bio mass/pine trees, natural gas or any other heat source. Sweden is buy many tons of pine pellets from the US to generate electricity. We are talking thousands of real jobs. But your government is the one that stands in the way of better jobs. Sad when other nations buy our natural resources to use for themselves.
maybe not a chemist, but know , a potential, danger. good thinking, dave
Except the money is being put toward space exploration when it should be put towards such efforts.
@@michaelb9940 barely any money is being used for space
@@luckysours8397 was this a joke?! 😂
In my opinion, the only problem is that river water is artificially cheap. This will cause some tension between inland and coastal cities feeding from the same river, since one of them doesn't have alternatives.
As for the brine, it doesn't sound that difficult to solve. It's literally just concentrated seawater that you need to dilute again. There's a lot of ways to approach that from pre-mixing with seawater to mixing with (treated) waste water.
You just dump the brine further out on the bottom. No problem given relatively small amount of salt water processed/
Essentially, we need more studies into what applications sea salt and/brine can have, beyond the food industry. Perhaps, a breakthrough in sodium batteries?
@@apostolosvranas4499 why? There is ZERO problem with putting it back into the sea
@@protonneutron9046 , the increased salinity would harm local saline, especially animals pf the bottom, and - in the long run - further increase the sea temperature as salt absorbs more heat than water.
@@apostolosvranas4499 wrong it doesn't. Decades of observation prove you wrong. This tech has been used for a long time. Run alone now
I know this may seem like an incredibly simplistic view on the topic but if thermal desalination is the process of boiling and capturing steam for purification. Then, couldn’t you theoretically utilize this steam for energy production? If you combined processes you could reduce infrastructure cost and product costs. Instead of fighting over fossil fuels as much as everyone is. Maybe, we should be enforcing policies relating to mandating water resources
Yes, combined-cycle plants gain efficiencies. Saudi Arabia does this extensively and CA should too.
@@proaudiohd Water-Problems were covered by 'Some More News'
and 'Second Thought'.
the problem is, of course everyone that produces energy wants every unit they can produce out of it sucked out. but you can't put a nuclear reactor on a desalination plant on a hydroelectric damn or vice versa... there's just no way to do that because 1) any one of these processes take a fair amount of space and machinery to do it and 2) to do it at scale you vastly ramp up the space needed for just one of these types of energy generation/farming. now if you want to design a hydroelectric damn that also has a nuclear reactor and a desalination plant, and whatever else - and you think you can do it more safely or cheaper than we're doing it now, i say go to it! but i think you'll find it's a lot more complex than you thought. perhaps there's a way to combine some of these processes on a very small one home version of a combined generator/desalinator/turbine. good luck
@@jerkchickenblog In order for a Molten Salt Reactor to work it needs to get up to 800C. Desalination would be a BY-PRODUCT, using the heat. So you get either electricity as a by-product of a nuclear desalination plant or vise-versa. This CAN be done if folks put their minds to it. Considering Gen IV Small Modular Reactors we could build where needed and expand when needed. Not sure if the heat process would make good use of brine or produce less of it though. Search TH-cam for "nuclear power for desalination".

What kind of questions
The problem with desalination is scale. Here in California a lot of people who apparently missed basic calculus are pro desalination plants. Leaving energy considerations out of it, the main issues are amount of water needed and amount of salt produced in the process. Ocean water is about 3% salinity. That's a lot of salt. Israel produces about 150 billion gallons of desalinated water per year. California uses about 40 billion gallons of water per day. So what Israel desalinates in a year lasts California 4 days. In the process those 4 days worth of water would produce in the neighborhood of 250 billion gallons of brine - or to put it in perspective roughly 15 million tons of pure salt. The world uses close to 300 million tons of salt per year - for all purposes from food to de-icing roads. That would mean about 20 days worth of California water consumption from desalination would produce the yearly world consumption of salt. Where do you think we're going to dump that much salt after the 20 days?
By the end of the day, desalination is an option for small areas and in California for coastal cities like SD, LA or SF. It's not an option to try to produce enough for agriculture. For California a much better solution to the problem would be to stop focusing on urban water use and reducing agricultural water use. It makes zero sense to produce commodity crops, meat and dairy in a semi-arid region. No, California doesn't need to be the third biggest meat producer in the country, nor does it have to produce 80% of the world's almond harvest at a price of almost 1 gallon of water per nut. Stop producing these things, grow something else that makes more sense for the amount of water that is available and urban water use, which is only 10% of the water used in California, will not matter much.
Well stated Uwe.
Shhhh, they really enjoy themselves going in all sorts of armchair magical engineering for desalination lol.
I think you're misunderstanding a fundamental concept here. Desalination does NOT produce salt. Your logic is based upon the assumption that this process produces salt out of thin air. When you return the brine to the ocean you're simply putting back the exact same amount of salt that you removed in the first place. In other words, it's a net zero process. What's important is being mindful of how the brine is returned to the ocean to make sure it's diluted enough to avoid areas of high salt concentration. Even then, there's nothing in this video that says high salt concentration is a bad thing. They said it "could" cause environmental impacts. This is super vague and implies that the environmental impact research is inconclusive.
I once calculated that you would need plants every 25 miles along the entire coast line of the US to provide 1/2 inch of rain daily to the entire US. This was based off the biggest plant at the time and its number I could find.
Someone could calculate for the entire world how many plants you would need to produce 1/2 inch every day for all the land in the world. This would not only grow the green on earth to 100% in a short time it would also cool the earth and cause a large amount of new weather. The grounds would soak up so much water bringing water tables back up and producing the ponds and lakes that once were. Dry areas will be full of life again and deserts will be green again and stay green. Trees would grow by the billions.
Though we would need a large amount of energy and time to produce enough of these plants. We may not need every single one of them. Once we start watering vast areas, what evaaprates off will form clouds which will rain in new areas that once did not.
@@kameljoe21 Nice story - a but unrealistic though...
I do believe desalination is the key to solving many problems. Although I would rather see the water and salt separate completely in this process and at least some of that salt dumped somewhere environmentally safe to reduce the effects that brine would have on our oceans. More costly, but also healthier. I'm sure with more energy advancements, desalination will become more practical.
We have a desalination unit on our sailboat, and love it. You may be interested in this/ it might answer some of your questions and concerns: th-cam.com/video/oxFHDGvJXQQ/w-d-xo.html
only issue is that there isn't any effects that brine has on the oceans. they have this idea that it would only impact a small area around the outlet, but they haven't found any proof of that after decades of these machines operation.
I live a few blocks from the harbor. Our water is ludicrously expensive. I live alone and have a small garden. I go to the laundromat to do my laundry. My monthly water bill is $100. This is Florida. It is very expensive here. So I bought dehumidifier and a small solar generator and wired them together. I get about 40 gallons a day which is just enough to keep my garden going on dry days. During rainy season I have a rainwater collection system and a 1000 gallon cistern.
water collection is illegal in a lot of states.
@@Will-jw5oc The vast majority of states have no restrictions at all on harvesting rainwater. A few states have some restrictions and only one state has a total ban.
@@Will-jw5oc that is incorrect sir please recheck

@sitdowndogbreath the fact this person has a 1000 gallon cistern is illegal. Nobody is allowed more than 110 gallons. Hence why i said it is illegal in most states because 110 gallons is only 2 barrels. Not. Alot.
Nestle: Now how does this affect me and how much can we make off it?
nestle is part of the problem. They are making the lack of water worse. People should stop buying nestle products if they care about water conservation at all in my opinion.
SO, we live in a civilization that can split the atom, that can put a man on the moon, and that can put a computer in everyone's home, yet You Want Me To Believe that this same civilization can't find a cost effective way of desalinating ocean water ??? Only a SUCKER would believe THAT !!!

If you have a pool, don't fill it with dirt like we did 13 years ago. Turn it into a huge rainwater storage tank. (We might try digging out our pool again and doing that.)
Why not just use the older evaporation and distillation method? Looks safer to me.

We really need to build the same kind of new generation desal plants that Saudi Arabi is doing, solar dome desalination. It is similar to the original kind of desalination talked about in this video, evaporation type, only is FAR more efficient and even a good amount more efficient than reverse osmosis type. You can also take the lithium and cobalt from the process and use those for batteries which are also very important in today's day and age, and would more than offset the the cost of desalination. In fact if the plan in Saudi Arabia works out, it would be a complete game changer in Lithium supply chain as well as potentially stop the huge ecological damage from lithium mining since that could be greatly ramped down.
We have a desalination plant here in Melbourne Australia. It has cost to date $3.5billion to build since 2012 and $649million of tax payers money to run per year. It can produce enough clean water to supply one third of the Melbourne population but they say that it will probably never be used as we have at least 10 years worth of water.

Tampa Bay has been desalinating for over 15 YEARS. The cost is $2.40 now (as of May 2020) for ONE THOUSAND GALLONS, which is easily bearable by consumers other than by Growers and those watering lawns... As Tampa Bay provides a mix of desalinated, and "regular" ground water from the reservoirs it uses, the "regular" ground water cost is $2.26 per THOUSAND GALLONS, or only 14 CENTS LESS per THOUSAND GALLONS.
When your choice is free natural water or an expensive artificially created one (which kills the ocean life in the process) what will you choose? In the old days people just move to the places where the water is still abundant. But with the current overpopulation thanks to all those modern technologies it could be difficult to do in a peaceful way, but still better then killing the whole life in the planet in a long run.
As the cost of the energy to run the desalination plants would be very high, why not use Thorium Reactors to provide lasting, clean energy from an off the grid source? What issues would need to be overcome to try this type of fuel arrangement?
What they should do with their “Brine Water” is to pump it into Large Shallow Brine Pits, and then use the Suns Rays to Evaporate the Water from the Brine, and then what’s leftover is Sea Salt. Then that Sea Salt can be sold to everything from Restaurants, Stores, and can even be sold/used on Roads that Ice up. California wouldn’t even have to ship it very far. It can be sold to states right above them where it’s known to Snow/Ice Up at. It’s a Win Win

EXACTLY!! LOL Screw them! This is basically propaganda saying that we need to consume less water, that we need to change our behavior and not to think that desalination is the answer to it. Which is a dam lie, we can use as much water as we want because the water that we use will eventually be evaporated anyway and go back into the atmosphere and then rain right back into the ocean. So even tho we put the high saline concentrates brine back into the ocean, it won't matter because the same amount of water to even out concentration levels will eventually rain back down!

Welcome to news.
The brine could be used to take the various minerals the land is missing, it would help limit the mining of those different minerals and therefore limit use of heavy machinery that wrecks natural habitats. Potassium is found in seawater and is used in gardens as well as healthcare. Brine could also be used in flow batteries(since its sealed i would try to put a limit on how many batteries are made ). We should still try not to take too much saltwater out of the ocean at one time, try to use the desalinated water to slowly add more water to the soil so we don't need to use as much. Give the ocean time to regain homeostasis with the water cycle and the rain will help wash the salt back into the ocean.
Desalination will keep on getting better, and since most desalination plants are pumping ocean water right next to deserts, then the brine can be concentrated in inland desert ponds, lithium extracted, and the dried salt mixed with sand and melted into glass using solar furnaces. The glass can the be used to make mirrors for more solar furnaces, bottles, and a host of other things. 🌞
The good thing about that process is, that you can do it when ever the Energy is available. So you can overbuild your your solar farms for your other Energy needs and dump the surplus Energy into desalination. In time, the Saltlake will become a resource pit for sodium wich we will need for Energy storage.

I think the answer is to use the use the power of gravity from the ocean as a hydro electric source for de-sal plants up and down the coast. (Just like the Hoover Dam, except up against the coast). Not only produces power to run the plant, but the turbines would produce excess electricity that could double as a power stations. So the water that runs past the turbines is de-salinated. Put the plants underground, Siesmic-proof). Would not even know they are there. Imagine no smokestacks. Safest way to ensure ocean biology to have the intakes well below the sufface, like a dam. Would start to de-acidify the coastlines that are presently putting a world of hurt on the ecosystem. Clean. Always works as long as there is water in the ocean. Ship the brine by-waste to great Salt Lake or to the desert where evap contributes to more rain. I'm sure the Salt lake can take a little more. The cost is now affordable based on what an acre ft. of water costs presently.

Mitigates the sea rising. Our imported water is the the Colorado River. If the level of Lake Mead goes below the intake inlets of the Hoover dam Vegas Stops. Game over. No lights.
De-sal plants would be a help in mitigating the rising levels and providing constant energy. It's not rocket science. The Israelis figured it out, we should to.
The brine flowing back into the ocean is bleaching it and it kills coral riffs and fishes, BUT there is an entire hotel/Restaurant build out of salt, so given that Saltwater is available almost anywhere around the world it would be THE perfect and cheap, renewable building material, in thick layers of 30 centimeters it's imune against rain and even hardens. Sort of like Ice. If I had the materials to dry bricks myself out of salt I would do it. But then again ... that takes effort and time.
Use reverse osmosis plants to get the bulk of fresh water, then use less efficient thermal desalination on the brine until you are left with only fresh water and salt.
or in smaller plant with lots of open space, just let the brine in evaperating area's to also produce sea salt and secondairy product,
you lose the water from the brine to evaperation, but also don't need to use the huge extra energy the thermal desalination uses..
Would the salty prime water not be neutralized by the melting Polar Ice Sheet's fresh water raising the oceans levels?
@@Crashed131963 if you tansported the extra salt water to near where the meltwater of greenland enters the sea it perhaps partly would, but locally it could possibly severly dustirb local ecosystems. The cool towers were created cause a few degrees warmer water seemed to have to much negative effect on river fish, artificial extra salty spors could do that harm to sea life too perhaps, the fact is we dont really know how it would affect sea life yet

@@rickabay I was considering having salt as byproduct, seasalt is used worldwide, so if you extra salt some water, why not use it to need way less evaporation time to produce the salt?
The main product stays the fresh water in that scenario!

Title: Harnessing Water intake in desalination plants from mesopelagic (below epipelagic) region
I'd like to propose an idea that has possible potential to help the desalination industry.
Imagine a desalination plant that deploys an intake pipe from mesopelagic region to the surface, and then pumps its feedwater from the opening of this large pipe on the sea surface. This pipe will continue to fill due to the capillary action and we do not need energy-intensive pumps to bring that "cleaner" water to the surface.
There are several compelling reasons to explore this approach:
1. Reduced Biofouling: Drawing water from greater depths could significantly reduce the risk of biofouling, a persistent challenge in desalination. By avoiding the epipelagic region where microorganisms thrive, we can minimize fouling and maintenance costs.
2. Potential for Lower Suspended Particle Concentration: mesopelagic waters typically have lower concentrations of suspended particles compared to surface waters. This could lead to system longevity and reduced costs.
3. Environmental Impact: Deploying a possible parallel line for brine disposal at the same depth can mitigate the environmental impact of brine discharge. This approach allows for more efficient dilution and dispersion, reducing harm to marine ecosystems.
4. Significant Savings: Energy savings, reduced maintenance costs, and improved desalination efficiency could translate into significant economic benefits for the industry.
I invite you to share your thoughts, ideas, and expertise on this proposal.

8:14 Don't dispose of the brine. Sell it to a company that will spray it on the flats and generate Artisanal Sea Salt that will sell for $18 per pound (j/k). As a side note, fully desalinated water and the resulting brine may not be required: brackish water or partially desalinated water can be used for some types of agriculture, one of the largest demands of water in CA. This would alleviate the burden on the fresh water supply.

We should try and seriously consider it. Especially since the sea levels are rising, great idea!
I realize that brine being poured into the ocean is not really mixing it in, which maybe a funnel could be built to do that (take in ocean water and mix it with brine water), but I had been under the impression a concern was that too many glaciers melting would disrupt the saline balance in the oceans. I'm also confused why the brine isn't being sold to companies that could use it (for saline solutions !). Someone else mentioned here in comments selling it to companies that produce salt for water softeners, or even for roads where it snows.
Maybe Brine can be put into an empty lake, than put back into the ocean?
The Brine could also be sold to areas with Hard Water/High PH to soften their water. Today, in 2021, as I watch this, over 120 Countries operate Desalination Plants. With the Rising levels of the Ocean Waters, Investing in Responsible Desalination Methods seems like a worthy Investment. Droughts are only getting worse & nothing can live without clean water!

@@peter-pg5yc That's not how water softeners work. LOL!
Isnt hard water and high ph water with high amount of bicarbonates and diluted salts or im missing something lol

so instead of desalination we can stop Geoengineering first so we can have a normal not manipulated weather as climate change does not exist only weather manipulation throught geoengineering and chemtrails. We the people are ngoing to stop all yours sick profit ideas !!!
Now all we need to do is figure out a way to make salt a fuel source.

Thanks,I worked in that industry year ago.
Several things. The American Southwest is out of water, we have to do something as 40 million people have moved there in the last 50 years. 2) The brine can be harvested for lithium which is critical for li-ion batteries and would remove a lot of the lithium mining, which is horrible for the environment. 3) New types of nuclear power are safe and produce zero greenhouse gases, look up thorium power sometime when you are bored.

I literally thought of this when I was a little kid. I thought if oceans were rising and we were losing fresh water to just use sea water to lower the tides.
The entire world’s water supply could come from the ocean and the sea level wouldn’t even drop an inch
Natalie the oceans will not rise at the rate originally suggested by scientists because as the heat on earth rises so does the evaporation rate. The fresh water being released from the melting poles is being evaporated at the same rate that it is being released. This needs to transpire to get the rain needed to regrow our forests and end drought.
However as long as man keeps polluting our atmosphere there will always be extra undesirable yet necessary heat to supply earths evaporation process. New York City is only a few feet above sea level yet the polar ice caps have lost well over 50% of their original mass. According to science that would put New York City underwater many times over yet the level remains as it has always been. Where’s the water? It’s in our atmosphere. It is why here in New England our sunny days that we used to have without a cloud in the sky are non existent. If we get sun it does not last long before the clouds move in. The water is in the atmosphere. Although your idea shows intelligence and it’s feasible to consider under those circumstances, we will never have to worry about rising sea levels to the extent scientists originally suggested due to an increased evaporation that coincides with the melting of the icecaps.
@@gregoryone90 that's not true. The data given by nasa and their observatories to not suggest a melting:evaporation ratio of 1 to 1.
@@gregoryone90 I'm sorry but your theory is incorrect. Just Google maps depicting water levels 30,000, 20,000, and 10,000 years ago. It's a huge difference. The bridge that animals used to cross from one continent to another was literally a land bridge. And you could've literally walked from America to Russia.
A lot of us have. Unfortunately we didnt do anything about it
1. Middle East sends a lot of oil tankers to East Asia where fresh water is plenty. On return the oil tanks are filled by seawater for balance. They could do this with fresh water and this could help (not solve) with the issue with some of these countries.
2. The brine is dense and heavy. What if nanobubbles are injected to the water? This reduces the density and might help with mixing with the seawater.
Im quite certain that combination of desalination and energy production is possible. Using good metal or other materials, and using very dark black and very bright white colour, and possibly mirrors.
Why can't we stock the left over brine in ponds to finish the drying out process and turn it into salt.
That salt could then be used to treat/de-ice public highways during the winter months
Or we can start pickling everything.
#LearnMMT macroeconomics
Just asking, but where would you dig these holes at?
Because its easier to dump it back into the ocean and salt Is cheap. The amount of space you would need, especially expensive coastal space would be massive. Think about how long it takes for you to evaporate a gallon of water even in the summer. Sure you can spread it out to increase surface area, but they're talking 50 million gallons of brine water a day. Thats roughly 5000 average swimming pools a day. But a pool, at its depth would take months to evaporate. So think about how big the area has to be for it to evaporate, and collect.
Desalination seems like a good idea for a place like California that faces large solar energy surpluses during the day. Run desalination during summer days when water is the most scarce and energy is practically free.
What abt its impact on marine life
Solar power will never be 'practically free', that's Madison Avenue disinformation destroying our public schools. The lithium wars will make 20thC oil wars look like Sunday picnics. What part of 'rare earth 15 years to hazmat waste' don't you get? Make the public and private golf courses provide their own water supply, that's where the water shortage is going. Big industries use 1,000,000s of gallons of potable per day, but only pay 1c's where we pay $1's. Make them pay full price.

Isn't the brine mineable into sea salt? That seems to be a big product for many uses.
We should use mangrove trees or another salt water plant as part of the pre desalination process! even reducing by 30% would make a big difference.

As a MIcroBioChemist from UCR I think Desalination should happen in the high and hot lands of Bakersfield and Riverside, if we pump salt water to higher grounds using a series of filters along the way: (as processing centers) [Nutrient Processing center taking Nitrogen, as well as ethyl and octane plant(1) near the coast, mega particle filtration "Uranium" near the valleys (Plant 2), Lithium, and silicate extraction before higher altitude (plant 3) and at the highest altitude and brine filtration and processing plant. Brine being a higher salt concentration of salt which makes it hard to get water from sodium electron energy we require more energy however since most of these Desalination plants are costal, and are all processing salt water and use fossil,], point being we can use the Sun to desalinate the water in the hotter parts of the state instead of burning fuel, and pumps using solar energy. we can restore the ecosystem in the ocean by reducing waste and on land by using that waste to provide nutrients to the land (Plant 1), and provide free energy, Lithium (plant 3) and uranium (plant 2) we need. We are focusing too much on one rather than all.

Why not evaporating the Brine in a big open field and sell the Seasalt?
Als ob du nur einen like hattest 😂
Because brine is not a problem. That was just a bunch of BS to invent controversy. That woman environmentalist who hasn't washed her hair in 5 years is just off her rocker. After the brine is released the water in the area quickly mixes with the ocean water. Look at the video 6:43. If there was a problem the animals and pants would be dead there. They aren't. That has much more life than you normally see when you scuba out there.
Salt? Salt is ridiculously cheap. Your operation has to be super efficient to make a cent. You need a lot of beach you can make into drying pools. That is very pricey here and generally public. And you are talking about one heck of a lot of brine.
Interesting perspective and honestly it comes as no surprise; it appears everybody financially involved has an agenda, in saying that dehydrating the brine would be the least controversial option, albeit costly.
Just evaporating isn't enough, there're many other soluble foulants in the brine water. The purification method usually involve a bunch of integrated technologies which are not a little amount of investment. So.. an intense feasibility study should be considered at first. Not all regions/countries can afford it
They do some of it for roads salts for deicing for many eastern states in the winter times.
make a big basin with a dome over top of it, pump sea water in it and then let the sun do its magic and evaporate the water which can be collected with a gutter system around the base of the dome. Also you can collect the left over salt that can be made into table salt, etc. Lastly agitate the dome (in order to break the surface tension of the water droplets) with something similar to the imbalanced rotor that is in your controller that lets you feel like you're shooting, crashing, etc. For desalination at night, use a solar panel grid to charge batteries, which then can be used to energize electrodes in the basin that can be used for electrolysis (causing hydrogen and oxygen to be separated out of the water as vapor that combines in the dome, making water droplets just like solar evaporation). Just an idea /shrug.

Southern California happens to be sunny. Solar energy production is easy. The technology to desalinate water has improved. Lower pressure filtration is now available. The electrical load on motors will be less. Combining solar electricity and easily available sea water can potentially create a Garden of Eden. The entire Southwest can benefit. The Colorado River will not provide enough needed water. Arizona and Nevada are already warning California about the coming droughts. When the water runs dry the public will demand action perhaps then cost will not matter.
Did you watch the recent congressional meeting with the federal department Bureau of Water Reclamation?

Also, heat energy is converted to work (tearing ions away from water molecules) this reducing global warming.

Nuclear or nothing
I would think that the advice would be going the other direction since Arizona and Nevada don't have ready access to an ocean. California should be suggesting to the landlocked states, well Arizona does have the Gulf of California but no infrastructure to transport water to their population centers, that they pony up funding for desalinization in the Golden State to free up more of what little is left from the Colorado River. These two states can't unilaterally decide to take more than the negotiated allotment because to do so would invite the places where the water comes from to do the same and starve these two states of the resource. The most intelligent thing would be for all of the states in the Southwest to work together on solutions.
@@steverichardson7417 Will there be a time in the future when nuclear isn't the most expensive option? I've been reading about Finland testing the use of sand in silos to store the energy from solar and wind. If something as low tech as sand is a good answer then that in combination with ever more solar development in California and the rest of the Southwest would be the low cost solution for the power needed. California is already paying other states to take their power at times of the day and year when it produces more than they can use. Nuclear can have a role but the cost needs to come down as well as the lead time for getting a plant online.
We could do anything if we truly tried.
Here's one idea: Siphon water from Greenland's meltwater ponds and lakes, into large re-purposed oil tankers. These ponds and lakes are increasingly appearing on Greenland's ice sheet, and speed up melting of the ice sheet, and increase the speed of glaciers moving toward the ocean. So, a win-win.
Here's another idea I came up with. It's desal. by evaporation.
Seawater would be heated by sunlight under a large structure (located near shore) that looks like a clear upside-down bowl. Air would be pumped out the top through a pipe that runs uphill (the higher the better) to an array of pipes that cool and condense the humid air into pure water. These pipes would be cooled by this amazing new tech: th-cam.com/video/7a5NyUITbyk/w-d-xo.html
The water in the upside-down bowl would be in a partial vacuum, and would actually boil. The whole system could be made more efficient by using the downward flowing motion of the freshwater to pull more air up from the seawater. Wave/tide power could also help power the system.
Yes, if we do it together.
There are actually scientific limits to things lol
Really, fly like superman and defy physics? Really?
Very informative and interesting thank you for posting.
Disposing off brine in a dessert would: 1. Help with humidity and rain, 2. Get back salt to where it originally came from, the land. What we don't want to do is throwing brine back to the sea (basically throwing the salt back to the sea, after some fresh water has been removed, thus increasing salt concentration in the sea).
Totally agree.
while you agree with your own comment, I have a minor disagreement with either one of the two. :
All the fresh water comes from natural evaporation over the large area of the ocean surface and concentrated evaporation along the breaking waves near the beaches. All the salt is left in the ocean, the rivers eventually pouring less salty water back into the ocean, net effect, yes added salt from the natural demineralization by the rivers . A process going on since time of the condensation of water, when the planet was formed by cooling.
Any salt concentrated in brines released by human desalination have a negligible, negligible, negligible effect on the ocean salt quantity.
¿No lo ves?
@@arturoeugster2377 then send it to the moon .
The sea needs it's salt to remain where it is. The answer is to make sure the water we use is returned where we borrowed it from, not to tera form the ocean for freshwater.
@@Samuraimindset-
Who is talking about terraforming.
The central point is that the huge natural evaporation cycle, which produces rain, snow, etc all over the world separates the water from the salt( 35 gramm pro liter)
and leaves enormous quantities of a weak brine on the sea water near the surface, eventually the rainwater collected by the rivers returns to the sea, so that practically the salt content remains constant,
Desalination units do exactly the same, except there, humans use that water first, leaving a microminuscule amount of salt in the sea. The concept of the brine disturbing the salt content of the enourmous sea volume is extremely false.
average sea depth 4000 meters Sea surface ~ 450 million square kilometers
volume 1800 000 000 000 000 000 m³,
compared to ~ 1000 m³ per day per large desalination unit. You could not measure the change in salt content from 35 GRAM per 1/1000 m³ with the most sensitive sensors. Typical illogical huge exaggeration of human induced changes.

The biggest cause of global warming, water shortage, poverty, increased prescription, and pretty much all major world problems are large public corporations. And who is in charge of keeping them in check? the government. But who controls the country's economy? The corporations. So it's hard for the government to place regulations on them for that reason. If one of those corporations feels there are too many regulations placed on them and they decide to up and leave the country then you can imagine the immense economic instability and damage it will cause. On top of that it is not clear what the solution is to make sure these corporations stop the wastage. Consumers obviously control demand but corporations can make decisions without considering those demands. I think they should divide these large corps into multiple smaller ones, bill gates has also suggested the same idea. But it is also unclear how to go about doing that. All I know for sure is the problems are due to them. but nobody knows how to manage them.

@@rickmorris338 Say what you want about the number of plants (which isn't high btw) and government conspiracies, studies such as the one I have cited predicted that the brine won't have significant effects on marine ecosystems. The salt that is returned was already there, mixed with water, what happens is that we take away some of the water. The amount of water the desalination plant takes away isn't high enough that removing some of it without the salt will change the concentration of salt in the seawater significantly, especially if you take note of the enormous amount of seawater there is where the desalination plant stands.
Profitability is directly correlated with ecological harm. Taking water directly from the natural water cycle is vastly cheaper, and if we consider all the positive side effects, it becomes even cheaper. The capacity is literally limitless. Off southern Mexico or Yemen, is enough water in the air to produce the Mississippi or even the Amazon rivers. The book Pluvicopia shows these figures and how the process is simple and reliable. If we can tap the natural water cycle, we can solve all problems considered impossible; CO2 reduction, Sea Level rise, Doubling the amount of arable land, and regional cooling are all durable with the natural water cycle. That's how the planet is supposed to work.
Interesting, as sea levels rise, due to melting attics and Greenland glaciers, changing the oceans salinity, perhaps desalination can offset this, if we can distribute the brine, using the oceans currents, although anything we do probably will have varying degrees of negative effects on the environment and sea-life, just a thought…

Being that desalination plants are seaside, integrate dedicated wind generators and solar. Others have pointed out sea salt production from the brine as well. Problem appears to be caused by open loops. Close the loop and there you go.
Hey! Right next to the desalination plant is a sewage treatment plant pouring fresh water into the ocean so stop worrying and use your heads. Net neutral saline or less.
My thoughts: we need high pressure to force seawater through a semipermeable membrane; the ocean depths have plenty of pressure, just put the intake and filter in deep water and pump the resulting fresh water?
Practical but the engineering will make it very expensive
Second stage: evaporate more fresh water from brine, get salt as a byproduct.

Great ideia, but the costs are too high for adding this stage using the Reverse Osmosis process. Thermal desalination already do that, but the costs are much higher then Reverse Osmosis. So yeah.... =/
@@DeathGosu, you're right of course. This was more like a joke. Kinda. Not great one, not terrible))
Was thinking the same, don't they have big fields where they evaporate water to create salt. Sounds like a oblivious good partner to use the brine as it contains more salt?
Why not sell the brine to companys that already have infrastructure in place to do this? I.E salt manufacturers who already rely on brine?
Or would it be more expensive to do and therefore infeasable?
I love the phrase "some projections". Its utility to scare everyone in any direction is virtually limitless.
What timing is that? pls
The water that they take out of the ocean, ends up in bathrooms and kitchen sinks and it goes into the stock of freshwater which eventually gets dumped into the ocean also it seems like that would mitigate some of the issue with salinity
Isn't the brine issue easily resolvable? Seems like a trivial obstacle like any other waste water, collect some of the salt on the way out if it really is dangerous, but I doubt it.
I am grateful for programs like this which promote discussion and reflection on Humanity's growing water crisis. As a college professor, I can refer my students to excellent presentations like this to deal them into the conversation, so thank you!
critical thinking exercise for your students
The California water commissioner dumped ALL of last year's ice melt into the ocean this year. That's why Lake Meade is drying up.
Most "crises" are manufactured by the government or are a result of negligence on the part of the government. This is why Katrina happened, and why Flint Michigan has poisoned water, still, to this day.
Get rid of the water companies that steal water. They take regular tap water and then put their label on it. For instances like Arrow head and Crystal Geyser. Both of those companies get their water from California. California is in a big drought as we all know. How about those two big companies stop taking tap water? I bet it would help California out and the rest of the states as well. Essentially they steal water, steal millions upon millions gallons of water.
There is no ‘water shortage’ problem. We have an income problem. Desalination would provide unlimited water. Perth in Australia is in a very dry area, so it uses desalination powered by solar to provide amble water. Very low cost once built. This type of water could then be pumped inland. Also most water is used very ineffectively as it is not priced correctly. Eg, water is sprayed onto crops and not dripped. Most of Australia has moved to dry parks rather than grass based. Israel has solved its water issues with both those techniques. Africa has an issue due to lack of money, not lack of water.
Exactly the solution I proposed. California ALREADY curtails 6000MW of Solar DAILY ... that power can be utilized to run desalination plants at a very low cost.
We have a water storage problem, meaning there is more water stored in plastic bottles. And is not evaporating . Not when more water is being bottled every year than is being drank and in turn evaporating one way or the other.
Water is more precious than gold!!
When it finally comes down to it no matter what the cost you will pay to quench your thirst
This has been fixed with accelerating mixture of brine with regular sea water to lower salinity and using diffusers at the end of the discharge tube and discharging into zones where the watered down brine will be within the tolerance of the area.
Out of all the different voices that I’ve heard, the one thing I got from them all is that PEOPLE DO NOT WANT TO D WHAT IT TAKES TO MAKE THIS WORK!!! It would ABSOLUTELY solve the world’s water problems PERIOD!!! That’s why the Ocean is the most vast water source there is!!!! It won’t go away!!!!
Jack up the price of water. We do not have a water shortage where I live but the price has increased from 30 cents per m3 to 17.00 per m3. It has been 5 years since I last watered my lawn. If it does not rain the grass turns brown and stops growing, saving the cost of mowing.
