Single Tank Aeration Units with Catalytic Carbon
Catalytic Carbon is the unchallenged best filter medium for reduction of the offensive odor in water commonly called hydrogen sulfide. Additionally, it removes moderate amounts of iron, improves the taste, and is also effective with reasonable amounts of chemicals in general. Catalytic carbon is granular filter carbon that has been specially conditioned for use with rotten egg odors and iron, but it also has all the chemical reduction capabilities of standard carbon.
Single tank aeration units with Catalytic Carbon can be used with eight or nine parts per million hydrogen sulfide and up to two or three parts per million iron.
