Yeah, I just thought exactly the same thing, it’s obviously got to be sealed, but kind of makes you nervous if it were to fail! A bit like when they said the Titanic was ‘unsinkable’!
Good detailed video, thanks. I have to wonder though doesn't the vaporized mercury present introduce a new hazard (to the indoor air quality) potentially offsetting any health benefit ?
It's the sealed vapor *within* the lamp which gets consumed over time. This is essentially the same as a regular incandescent and fluorescent bulbs found throughout your house.
5 Micron minimal water inlet filtration. Got it. Otherwise the living organisms can hide behind particles... I will filter to 1 micron at least. Thank you for this.
5 micron, then a 1 micron then add a .35 micron filter. Yes, they make them that small. A .35 micron is equal to 350 nanometers. Viruses are around 25 nanometers in size. Then zap the viruses with the UV light to kill them. :)
Can you take a handheld uv lamp to treat a rainwater catchers / ibc totes this lamp is also used to visually inspect dye that checks for leaks you have to wear eye protection with the lamp
Very informative video thanks for posting. However there are just a couple outstanding questions Which you hadn't touched upon. 1. How much time does the UV light need to stay in contact with the water passing though it to fully be effective in "killing" all the bacteria which might be present? 2. Is the light on some sort of limit switch which would turn the light on and off when it senses water flow, or is it on all the time? Personally I would think you could extend the life of the bulb if it is not on when there is no water usage being passed through the system.
blue LED is the last LEDs that were made and UV is still in it's infancy in LED. The benefit to those is they can turn on immediately. These types of lights take a long time to "warm up" so there's no on/off unless you don't want to kill everything. Also the living organisms will move up the pipe by themselves while the water isn't flowing so it isn't good. Now there are methods to combat this, if you install 2x (two) of these units + a check valve you can pre-kill everything and then kill it again a few feet down the line, this allows you to do a on/off system without worrying about bacteria swimming down the line, also without having to worry about them getting past while the lights warm up. I'd also have a timer for a minimum of 2 minutes on time when they do turn on, so it isn't on/off really fast or whatever.
it takes upto 10 seconds of UV light at the correct wavelength (100-280nm)... which is why i don't understand these systems.. there is no physical way the water in that filter gets 10 seconds of exposure while the water is actually flowing unless you are using a trickle of water... to actually be effective.. you would need about 5 of these units in-line to actually be effective
please sir do respond asap. i have a 3 stage water filteration plant and there is button that lights up the uv light in the chamber, but i donot understand does this uv light have to be on 24/7 even when i am not drawing the water from the filter.
My water is at 11 hardness .. does this affect the uv light ? I had some water treatment sales guy tell me I need a water softener or the uv won’t work .
It needs transparency for the light to shine through and kill the living organisms in a product, so it might work in water but won't be as effective in products with color.
What about putting a UV light (waterproof, of course) inside an RV freshwater tank? I'd like to use UV, but don't have any more room to install a separate UV filter.
I for see many problems with this unit. A. How does the quartz sleeve stay clean? B. How will you know if the glass is clean? Bc I seen them dirty in less then 6 months. The best most effect system I saw was made by Hallet. They have wiper blades and crosslight sensors
4:38 you have to replace the UV lamp because the mercury vapour will "dissipate" and "go away" over time.... lol Where does it go ? Through the glass? Into your water that you are drinking? How much mercury "goes away" into your drinking water? Mercury is extremely toxic. Please explain more about why you have to replace the UV bulb. I thought they lasted forever. I thought mercury can't "dissipate" or "go away" through glass. I've seen mercury thermometers that are many decades old and no mercury escaped through the glass so where does it "go away" to in a UV lamp? please explain this.
@@SiriusC1024 I guess it's safe but it would be much safer and easier and less expensive to use LEDs. Also I since found out where the mercury goes, it breaks down into several different isotopes, & one of them does get absorbed by the glass tube it's in, but it probably wont get all the way through the glass.
@@Galv140577 I looked for LED that emit UV. You need UVC - the highest frequency UV light - to zap the germs and I could only find LED's that emit UVA.
1...For how long does the water should keep in contact with the UV light to be disfencted?? 2... Is there a reference to read more about this issue?? Thankyou very much.
Some salt water enthusiasts utilize UV sterilizer manage certain things within their tank. Those who use the sterilizer have noticed a drop in algae production. I'd recommend doing a google search on this topic and maybe youll stumble on a discussion regarding uv sterilizers for homes with algae flavored water. Also get your RO unit inspected I've heard of bacterial growth within the tanks.
I am on a city water 💧 and when I turn on the ultra violet the water goes funky teast. I called the company and they Saud because the city might use ozone to clean the water abd ozone react with ultra violet. Is this accurate?
Hi guys, i am thinking of starting a a bottle water from rest water source( river), now sure where to start and how to go about it. Anyone can point me in the right direction?
Thank you John for the explanation. i had one doubt- I guess the UV chamber is Stainless steel. I saw many of the water purifier these days has Aluminum UV chamber. I personally don't like Aluminum, but what is your view, is is fine to have Aluminum UV chamber?
When I use the uv light, the water 💧 teast weird. I called the company and they said it because the UV react with ozone the city use to treat the water. Is that correct?

Like how you only respond when someone is looking to purchase your equipment, but when someone has a question about your equipment, crickets...
He says that the mercury will dissipate and contaminate your water in this fully enclosed water system, so who's buying it anyways ? ))
Great explainatory video. Many thanks. How many Watts does this use? As I intend to use it for an off-grid situation.
What about an UV-C LED instead of a Mercury Lamp?
The lamp uses mercury! How is it safe for drinking water?
Yeah, I just thought exactly the same thing, it’s obviously got to be sealed, but kind of makes you nervous if it were to fail! A bit like when they said the Titanic was ‘unsinkable’!
John, Thanks for the video. I understand that is a UV-C bulb, what is it's wattage...15, 25, 50 Watts?
Can this kill mold that might be in your RO filter?

Yes, depending on wattage, and if its the right wavelenght , easier to just buy a uvc lamp and immerse in in it
Thank you John. Very informative and on point.
Though the quartz sleeve is very brittle, is something like the Pura UV system ok to use within a moving vehicle such as an RV?
Thank you, i gained additional information. I have had a system for 5 years and your video enlightened me. Thanks

Not 100% sure of the relevance here, but at 0:55 he mention virus' as living organisms, but they are not living organisms.

So the mercury "evaporates"... Into my drinking water?
Thank you John. Very informative and spot on!
Hello,
Thank you for the enlightenment. Please I'll like to ask if this UV water sterilizer can be used in a catfish hatchery to purify our water
so what happens to the organisms which is present i the time. will it cause any problems even though it cannot reproduce?
Could the UV system rid well water of Sulphur bacteria?
Do you have a business in Tasmania? Cheers
How do i reset the timer, it wont reset it goes to 39 days and stops wont reset to 365 days
You’re a good teacher, sir.
Thank you.
How much do the bulbs cost every year
how much power is needed for the UV lamp? can a solar panel work.
Does the use of this harm you though ?
What studies are there supporting it ?
I’ve used a steripen all over the world . I assume that it doesn’t kill worms or eggs ?!

City water is contaminated by fluoride. Can’t do much
what? waste water is not possible to run thru this system
Where does the mercury vapor dissipate to?
Radiation against water then you drink it
the sound is not good I am quite disappointed
so touching for an excellent video
I had one question doesn't that makes your immune system weaker because you are not exposed to any kind of bacteria or viruses
No. Your body is constantly exposed to bacteria and viruses. Making sure you have clean drinking and bathing water should be a priority.
Excellent video!
That was informative. Thanks!

Does it remove flouride in the water?
Only organisms like bacteria etc. Doesn't remove chemicals.
It doesn't remove anything only deactivates the cell so they can't form new cells

Repeating the same words 4 times over isnt very helpful.

Why does everyone put the UV system last in the chain? wouldn't it be put first?
Water needs to be clear for it to work
