WebThe breakpoint chlorination dose is the dose of chlorine that satisfies all chloride demand of water so that further addition of chlorine will result only in an increase in free residual chlorine. The safe dosage of chlorine is 1–2 mg/L but during an outbreak of any epidemic it has to be increased by several fold (e.g., 10–15 mg/L) and is ... WebBreakpoint chlorination . Break point chlorination is adding enough chlorine to eliminate problems associated with combined chlorine. Specifically, breakpoint chlorination is the point at which enough free chlorine is added to break the molecular bonds; specifically the combined chlorine molecules, ammonia or nitrogen compounds.

WebExample: An 80, 000 L pool has 2 ppm free available chlorine, and 5 ppm total chlorine. Liquid chlorine at 5% is used to shock the pool. Step 1 : Combined Chlorine = Total Chlorine - Free Available Chlorine. C.C. = 5 ppm - 2 ppm. =3 ppm of combined chlorine. Step 2 : 10 x 3ppm = 30. Therefore the FAC residual in the pool must be raised to 30 ppm. react ws proxy
