It can be used to remove ammonia from water. The bleachy smell around chlorine pools comes from the chloramines or Combined Chlorine in the water. Total Chlorine: To see if shocking is needed. The breakpoint curve is a graphical representation of chemical relationship that exists with constant addition of chlorine to swimming pool water containing a small amount of ammonia-nitrogen. Disinfection Breakpoint Chlorination. Occurs when no organic matter is available to react with the chlorine. This graph represents a swimming pool where bathing has ceased and no further ammonia-nitrogen is introduced into the pool. Total alkalinity is to pH what cyanuric acid is to free chlorine.

A waste treatment plant handles 1,500,000 L/day of sewage that contains an average of 50 mg/L of NH3-N. How many grams of Cl2(aq) must be present daily in the wastewater to remove all of the ammonia? endobj Since the reactions lower the pH, additional alkalinity as lime might be needed if [NH3] > 15 mg/L. (914.85 fl. To reduce the amount of combined chlorine it is necessary to shock the swimming pool water to reach the chlorine break point. Chlorine is most effective when Total Chlorine (TC) is almost equal to Free Chlorine (FC) and Combined Chlorine (CC) is near zero. = 6.175 Lbs.) Per lb. FIGURE 6.2 Breakpoint chlorination curves showing removal of ammonia from wastewater. = 14.96 Lbs.). Calcium: PPM. higher the effluent ammonia level, the higher the chlorine demand. = 6.175 Lbs.) RO systems use a semipermeable membrane that removes dissolved solids, including ammonia. Point 3 is called the breakpoint. Avoid scented bleach and bleach with additives. The generally accepted formula for breakpoint chlorination is 10x the level of Chloramines in the pool to reach the breakpoint threshold. How Do You Calculate Breakpoint Chlorination? Pool Volume: Gallons. Once the chlorine demand has been met, breakpoint chlorination (the addition of chlorine to water until the chlorine demand has been satisfied) has occurred. oz. The rate of ammonia removal is most rapid at pH = 8.3. We multiply 1.0 x 10 =BP 10 FAC 1.0 = 9.0).

Combined Chlorine = Total Chlorine - Free Available Chlorine Breakpoint chlorination is a technique used to remove combined chlorine by adding free available chlorine. Calculation of calcium hypochlorite dose is based on the optimum dose at Breakpoint Chlorination (BPC) in order to maintain the residual chlorine from the addition of increasing doses. Shocking / Breakpoint Superchlorination FORMULA: Total Chlorine subtract Free Chlorine equals Combined Chlorine / Chloramines. If the pool is too cloudy and the drain is not visible from the side of the pool it is unsafe to swim. P.s. I do hope you found it informative and helpful. View All Technical Notes. Break-point chlorination In this method, the chemical action takes place in four stages as shown in the figure by gradually adding chlorine to the water. The addition of chlorine to a water that contains ammonia or nitrogen-containing organic matter produces an increased combined chlorine residual.
