  • How do you make wastewater drinkable? It starts at the sewage treatment plant.
    Ongoing droughts are straining the supply of clean drinking water. One solution might lie in an unexpected source: wastewater. Through a method of purification called reverse osmosis, Orange Country is making millions of gallons of dirty water drinkable again.

    This is pretty amazing, even tho many American cities have old outdated water pipe systems, to be able to even slap a filter in your sink and drink it is still a marvel.

      I would never drink tap water because in America tap water is like 80% of our bottle water is mostly recycled sewerage water and filters will not protect you from catching a deadly diseases as filters only remove 98 to99 % of bacteria from the water which leaves you with 1to 2 % of bacteria getting through so you have a higher chance of contracting a disease or illnesses from recycled water, then one would from all natural water resources.

    I wish that they would have explained the purpose of the aeration better. Adding oxygen allows bacteria to quickly use up the nutrients in the water. This has two purposes: it reduces biological contamination by removing bio waste. But it also makes it safer to return the water to rivers and oceans. Natural water systems would be thrown off balance with such a large influx of nutrients, causing such problems as algal booms, or deprivation of oxygen by bacteria that are eating up the nutrients and using up all the O2, suffocating other life. Which makes me wonder why California has been simply dumping waste in the ocean when they are ostensibly the most environmentally minded state, when other states have been aerating waste water.

      It really is very clean by the time it finishes being processed. Most of it is accomplished by bacteria and bugs. It requires constant monitoring, documentation and constant adjustment to get the output water clean. The two main causes of problems in a wastewater system is chemicals that kill bacteria and "I&I" (inflow and infiltration) by rainwater.

      @@djayjp You probably shouldn’t make judgements when you have little to no idea what’s being done. Nobody says that water was potable, only clean enough to be released. Do the Mississippi or Amazon rivers look crystal clear when they run into the ocean? Of course not. I’d pretty much guarantee that water being released is significantly cleaner than the water from a major river.

      @@josephpiskac2781 While sunlight is free, solar distillation is inefficient and slow, requiring large surface areas and significant time to produce a small amount of distilled water. Reverse osmosis (RO) filters, on the other hand, are more efficient and can process larger volumes of water much faster.
      Also RO systems are compact and can be implemented in various environments, from household units to large municipal plants. Solar distillation systems are cumbersome and require constant exposure to sunlight, limiting their usability in cloudy or non-sunny regions.
      In regard to water quality RO filters remove a broader range of contaminants, including salts, bacteria, and chemical pollutants, providing higher quality water compared to solar distillation, which primarily removes salts and some impurities but may not be as effective against all contaminants.
      Reverse osmosis is just overall a better way of providing safe drinking water. But it would be nice if we could utilise the sea water someday.

      I see it more as a combination system. Reverse Osmosis is expensive due to the amount of pressure needed to force the water through the membranes. You could prefilter with larger micron filters that remove heavier particles but allow smaller ones through. Then you could utilize the deserts to focus sunlight to a focused point that then reflects down onto a greenhouse with a pipe at the top for the vapor distillation.
