Fairly common well problem...H2S...rotten egg smell......
What is the best treatment? Tested at 1-2 ppm.

Explain some of the acronyms for us treatment challenged people please? KDF = ???
I have used the catalytic carbon with air oxidation with fair to good results.
I don't have a specific case, just in general.

Dittohead, you have obviously had better luck than I have with KDF. Yes, it has its place in water treatment but my attempts to apply it to H2S ahve not turned out very well. With any backwashing device, an incredible high rate of backwash flow rate is required according to tank diameter. Without consistently and frequently lifting the bed, solidification and thus channeling occurs greatly shortening the life of the media. Media replacement becomes expensive and frustrating.
An upflow tank will almost never get the flow rate required to move the bed around unless it is placed in front of the pressure tank with flow restrictor to regulate precise flow rate.
My all-time favorite use for KDF is in smaller refillable cartridges placed ahead of ROs where a whole house sulfur system is foregone, unavailable or price prohibitive. A small test valve is placed following the filter to determine media life. here flow rate and channeling is not an issue.
KDF is also used in shower filters as it is not affected by higher temps as carbon is. It could even be placed after a water heater.
How wide is your tank and what valve do you have on it?[/QUOT
I agree that KDF is a difficult media to get to work right, and it has a bad reputation, but... I have had great success with it. It requires a backwash rate of 30 GPM per square foot of bed area, even higher rates when the water is warm. A 7" diameter tank requires a 7-8 GPM backwash rate. It should be done no less than every few days if the media is being hit with iron, manganese, or hydrogen sulfide. It will turn into a cement block if this is not done. In my application, I have a 7x13 tank that is backwashing every 15-20 days, but it is municipal water that is very clean. I can also get over 15 gpM flow rate through it and still acheive 95% chlorine removal. KDF is similar to pyrolox, it is an amazing media, but if it is applied improperly, it will not work , and it will not last.
We make kdf/gac filters, we even have the KDF manufactured into foam pads for pre-treating GAC filters, they work great and have a huge chlorine and heavy metals capacity.
We have even had good luck with the Canpro Media guards, backwash rate is the key.
BTW, i have a 7000XTR quad system, more prototype than functional. Check out this link to see my system. Note: the system has been changed a bit, more gauges, controls, etc but the basic function is still the same. https://terrylove.com/forums/showthread.php?45302-Prototype-system&highlight=prototype
Tank number 3, the smallest tank is the KDF55 tank.
I have had success with KDF but backwash flow rate is high and typically water treatment equipment is applied to well systems so the pumps output is a factor. Before going with KDF it is important to make sure the well pump has enough ooomph (technical term because we have been accused of being too scientific here and confusing the posters LOL) to backwash the bed properly.
Odor does not cause high iron or manganese and high iron and manganese does not cause odor.Oder is defiantly the cause of high iron and manganese just under 2ppm iron and just over 1ppm manganese. its in cold and hot water. The standard style water softener usually generally enough to keep the H2s at bay except when i am away for a few day 3 or more. I would like to get away from the salt water softener an go to a descale-er mostly environmental I live on the edge of a managed watershed boundary and it be nice to not have salt backwash eventually run off into the streams near the house. I use a RO for drinking water and it has a KDF 85 GAC BB Slim and it is great so I know the KDF works with my water. I think Ill add the Upflow KDF that I originaly wanted to go with and see if that lasts if it holds up for a year then I think it would still be worth it in my situation. ill just replace the media yearly... thou I cant imagine that ill use close to 300,000 gal in that year thats what I figured 15-18 lbs of KDF should last? any and all advice is appreciated...
This is awkward, but...
