Bacterial Sulfide Degrader

PSS Formula 110 is a broad blend of carbonaceous bacteria plus thiobacillus cultures. The thiobacillus cultures use sulfides, including H. S, as the energy source for their metabolism. In wastewater environments, the PSS Formula 110 product reduces sulfide compounds to elemental sulfur. The product is used to reduce toxicity caused by sulfides or for use in odor-reducing programs.

PSS Formula 110 will work in low pH and low oxygen environments.
