How to calculate chlorine demand
Web3. To calculate grams of 65% calcium hypochlorite (granular or powdered chlorine) required to disinfect the water in a tank. For example: To achieve 5 mg/L chlorine in a 1000 litre tank add approximately 8 grams of 65% calcium hypochlorite. Please note the above calculations are only estimates. The amount of chlorine required to be WebChlorine quickly oxidizes hydrogen sulfide into a tasteless, odorless form. Continuous chlorination also effec-tively removes iron and manganese that can occur in association with hydrogen sulfide. Chlorine demand (concentration) and contact time are very important to successful chlorination. The amount of chlorine needed to react with
