Hydrogen Sulfide Control Case Study

This three-year case study evaluates the effectiveness of using microbial products in a collection system for Hydrogen Sulfide control and compares the cost with a nitrate chemical program.

The study shows that H2S was reduced to less than 10ppm 95% of the time.  The cost of the program was 41% less than the nitrate chemical program, which saved them over $28,000 per year. The program also had additional benefits downstream at the WWTP including reduced oxygen demand (BOD), improved solids settling (lower sludge volume index), and reduced odor.
