Thank you to everyone for the information - I learned a lot.
I thought I would give everyone an update. This centaur carbon system is amazing so far. We are not adding any chlorine. There is a passive system to suck air into the line before the pressure tank, and there is one to take it...
Thank you Bimr for the scanned information!
A company in my area is going to try a Centaur Carbon System on my water. I did a search through the archives, and I can not find this product mentioned. Based on Calgon's website, this is a carbon product designed specifically for H2S removal...
Thanks Bimr,
You have indicated that I need to inject about 20 ppm of chlorine, and I will have a residual of 10 ppm to remove all H2S. This seems to be consistent with my experiences. Is it easy for you to explain the math/chemistry in terms of how you generated this number (I have lost all...
Are potassium permanganate systems with the Greensand filters a better alternative when you have high pH? I just learned that this is what a number of my neighbors have, and they are happy with their water. But, their wells are at a different depth than me, so I don't expect it is exactly the...
Stephenw22, thank you for the retention tank idea!
Bimr, I latched onto the SRB idea, because it was something that might explain why there is no chlorine residual on the hot water (and smell). Your prior posts explain that the temperature promotes ionization and hydrolosis. Does this imply...
Thanks Stephen,
It seems there are two possiblities:
1) There is a colony of SRB's in the hot water tank and the H2S generated by them is consuming the chlorine.
2) The water chemistry is such that the heat of the water tank is consuming the chlorine and some of the HS ion which is present at...
Thank you,
- in the oil patch, SRB's survive at temperatures well in excess of the temperatures in hot water tanks. Is your ascertion that they are still producing H2S (even with a continuous chlorine feed >> 0.5 ppm), and this is what is consuming the chlorine in my hot water tank?
- someone...
Assuming the chlorine oxidizes all available H2S before the fluid gets to the hot water tank, is it possible that some of the HS through the addition of heat is converting back to H2S and giving a smell?
It is not a new well. I don't know many of the neighbors, but the ones I do know, have...
If teeth absorb fluoride from tooth paste, is it also fair to say that fluoride is absorbed through the skin when bathing? Or is this a bad analogy. If it is correct, perhaps a whole house RO is the only good alternative?
It is my understanding that almost all of my sulphide exists as the HS-...
Thank you,
In all of my reading, and asking local professionals, no one can explain why there is no chlorine residual on my hot water and there is a chlorine residual >10 ppm on the cold (measured at the tap). I have been monitoring for months, so these aren't bad readings. At present, I am...
Thank you bimr,
I don't know the hydrogen sulphide concentration - where can a guy get a test kit (I'm in Canada, so a source up here is even better)?
I have heard of locals pumping water from their well into 300 gallon atmospheric tanks in their basement and adding 0.5 ppm of chlorine. The...
I have H2S in my water, excessive levels of Fluoride, and it has a high pH (>8.5). There is a chlorination system (Hypochlor 12) and carbon filter installed. When I add sufficient chlorine such that the hot water no longer smells, the residual chlorine on the cold water side is >10 ppm. I am...
Thank you,
There was a sticker on one of the vessels, so I contacted the installer of the system. They indicated that I shouldn't have any more than 1 ppm of chlorine coming out of the retention tanks, or I would rapidly deplete the carbon (I don't know if deplete is the right word)...
Thanks Gary,
Your response generated four questions:
1) What level of chlorine kills SRB's? I'm assuming 4 ppm only removes H2S, but doesn't kill them? I'm wondering if I can just turn up my chlorine pump, or if I should be removing the anode and dumping a pail of bleach in? Any description...
The H2O from my well smells like rotten eggs (H2S). From the well, the H2O goes into a large pressure tank (~50 gallons), and a larger fiberglass retention vessel (~80 gallons). Chlorine is injected immediately before the pressure tank. From the rentention tank, the H2O enters a carbon...
