Pilot Studies In North Carolina With Hydrex™ Odor Solutions

Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H₂S atmospheric concentrations of 300-500 ppm. Both clients desired H₂S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

Wastewater collection systems are plagued with H₂S generation and the resultant odors and corrosion. H₂S is formed by Sulfate Reducing Bacteria (SRB) under anaerobic conditions.
