WebTotal Chlorine (TC) – Free Chlorine (FC) = Combined Chlorine (CC) 7.0 ppm – 2.5 ppm = 4.5 ppm Step 2: Calculate the Breakpoint Chlorination (BPC) amount The accepted amount of chlorination that is needed for breakpoint chlorination is generally 10 times the level of your chloramines (or Combined Chlorine). WebBreakpoint chlorination, on the other hand, would decrease the production of N-nitrosamines (Mitch and Sedlak, 2002), but may introduce other by-products, i.e., cyanogen chloride (CNCl) (Shang et al., 2000) and THMs. In this study, cyanide generation is examined under two disinfection conditions -- breakpoint chlorination and chloramination.
Webinvestigators of breakpoint chlorination have found that the breakpoint chlorination for complete ammonia removal ranges can occur at C1:N ratios less than 10.14. A ratio of 7.6:1 might represent an over all reaction such as 2NH3 + 3HOC1 -> N2 + 3HC1 + 3H20 (8) Two possible reactions that would result in this ratio are 2NH2C1 + HOC1 - N2 ...
