METHOD AND APPARATUS FOR CONTROLLING SULFIDE GENERATION

摘要

Systems and methods for reducing odors utilizes oxidation-reduction potential to characterize the quality of water or wastewater and control addition of a species thereto that reduces or inhibits biological sulfide generation. Oxidation-reduction potential is measured at a downstream station and, based on the measurement, a nitrate compound is added at an upstream station to promote inoffensive biological products instead of foul-smelling products.
