Added chlorine (mgA) Fig. 1. > Combined chlorine: consists of mostly chloramines, which are formed when ammonia is added to . For breakpoint chlorination, enough chlorine must be added to the water to break down the existing chloramines, oxidize the contaminants to produce new chloramines and then break down the new chlorines as well. Specifically, breakpoint chlorination is the point at which . The reaction is very fast and both ionized (NH4+) and unionized (NH3) forms of ammonia are removed. 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). The theoretical amount of chlorine required is, 7 6 g 2 x 61,800 g N = 470 kg Cl2/day, or about 1036 lb/day. Calcium: PPM. For background on what the various numbers mean, see Basic Pool Chemistry. STEP 7: We multiply Step 2 by Step 5 by Step 6. 2. Example 6.2: Calculate the Chlorine Needed to Remove Ammonia. Water Treatment Word of the Day November 25, 2019. Also called Chloramines, are one of the main sources of discomfort and irritation in a chlorine pool. This process is called breakpoint chlorination. Chlorine is most effective when Total Chlorine (TC) is almost equal to Free Chlorine (FC) and Combined Chlorine (CC) is near zero. Free Chlorine (FC) sanitizes the pool by combining with the contaminants and forming Combined Chlorine (CC), which is mainly chloramines. A good approximation is the shallow end depth plus the deep end depth divided by two. NotesUnless you are shocking your pool, it is always best to add less than the full amount, wait a little while to allow the addition to mix thoroughly, and then retest to see where you are. The ideal pool pH level is 7.4 to 7.6. The 10x rule isn't actually correct in terms of Combined Chlorine (CC). Q 3 . The oxidation processes with chlorine occurring between points 2 and 3 give a decline in residual chlorine. EVERY time I've done this test, the sample is clear, never cloudy. Thank you very much for reading the post. Boil the water for at least 10 minutes, or longer if the ammonia levels are high.
