THE PROBLEM

The West Rankin Utility Authority wastewater treatment plant in Jackson, Mississippi treats between eight and 10 million gallons of wastewater a day with a capacity to treat up to 20 million gallons. The newly built plant serves state-owned facilities and customers in multiple cities, including the State Hospital at Whitfield. The process of dewatering digested biosolids releases H2 S gas in the air, which causes a very distinct and unpleasant odor. The facility needed a solution to remove the odorous gas from the air because it was receiving consistent odor complaints from the surrounding neighborhood.
