A WWTP is disinfecting final effluent with chlorine. The target applied chlorine dose is 6.0 mg/L as Cl2. The average plant flow is 2.8 MGD (SCADA also shows about 1,945 gpm). The chlorine contact chamber volume is 85,000 ft³. Using the pounds formula (lbs/day = mg/L × MGD × 8.34), what is the required chlorine feed rate in lb/day to apply the target dose? Assume 100% available chlorine and ignore chlorine demand.
