Breakpoint chlorination refers to a method used specifically for the purpose of breaking apart and removing combined chlorine or chloramines. Free Chlorine (FC) sanitizes the pool by combining with the contaminants and forming Combined Chlorine (CC), which is mainly chloramines. Answer: By equation 6.8, 3 moles of chlorine are needed for every 2 moles of ammonia nitrogen. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Combined Chlorine multiplied by 10 equals the level of free chlorine necessary to kill Chloramines. Combined Chlorine = Total Chlorine - Free Available Chlorine Breakpoint chlorination removes combined chlorine by adding available chlorine. In spite of being quite regular, your pool has turned cloudy and you can smell the chloramines building up. We're not around right now. Know. Most annual plants are not sensitive. The beads are able to attract and remove the ammonia ions, leaving the water clean and odor-free.
