Chlorine is most effective when Total Chlorine (TC) is almost equal to Free Chlorine (FC) and Combined Chlorine (CC) is near zero. Breakpoint chlorination is the quantity of chlorine that is just enough to meet the chlorine demand of the contaminants. higher the effluent ammonia level, the higher the chlorine demand. Per lb. 2-4ppm Free Chlorine for Residential Pools, 3-5ppm Free Chlorine for Commercial Pools. Does your pool need breakpoint chlorination?

Depending on the quantity of other oxidizable substances in the wastewater, the plant operator should be prepared to use up to twice this amount of chlorine. In our example, we are using sodium hypochlorite. Breakpoint chlorination is the point where chlorine levels exceed the oxidant demand, and the water begins to build a residual of free available chlorine (FAC). What, anyway, is breakpoint chlorination? They move with the transpiration stream and accumulate in the leaves where leaf burn and drying may result. How much Lithium Hypochlorite will it take to reach breakpoint for a 75,000 gallon pool, if the FAC is 0.6 and the TAC is 1.5? Combined Chlorine = Total Chlorine - Free Available Chlorine Breakpoint chlorination is a technique used to remove combined chlorine by adding free available chlorine.
