The flow is 12.5MGD. What should the chlorinator setting be in #/day? 3. The dosage at the treatment plant is currently 6.9ppm. Demand has increase by 0.5ppm. The flow through the plant is 9.5MGD. What will the chlorinator setting be in #/day if the dosage is increased to cover the increased demand? 4. The chlorine feed rate at a treatment plant is 1050#/day. The flow through the plant is 12MGD. What is the dosage in ppm? 5. The chlorine feed rate at a treatment plant is 650#/day. The flow through the plant is 6.5MGD. The desired residual is 7 mg/L. What is the demand of the water in ppm? 6. A filter has a surface area of 860 ft. What is the filtration rate in gallons per minute per square foot if it receives a flow of 5,200gpm? 7.
