WASTEWATER TREATMENT CASE STUDIES AND WHITE PAPERS

  • Pilot Studies In North Carolina With Hydrex™ Odor Solutions
    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.
