The 10x rule isn't actually correct in terms of Combined Chlorine (CC). Breakpoint chlorination involves the use of chlorine (in the form of gas or sodium hypochlorite solution) to chemically oxidize ammonia and convert it to nitrogen gas. Why is the ratio important? Subtract the free available chlorine (FAC) from the total available chlorine (TAC) to find the combined available chlorine (CAC) level. Chlorination can be used to remove dissolved ammonia and ammonium ion from wastewater by the chemical reactions, Ammonia is converted stoichiometrically to monochloramine (NH2Cl) at a 1 to 1 molar ratio or a 5 to 1 ratio by weight of Cl2 to NH3-N. NHCl2 (dichloramine), and NCl3 (nitrogen trichloride or, Suggested Maximum Parameter Levels in Water Used for Crop Irrigation", Parameter Units total dissolved solids (TDS) mg/L specific conductivity mS/cm. Region B: Adding more chlorine oxidizes chloramines to N2O and N2. Grazing animals may be harmed by pasturing where NO3 levels are high.
