WebMaintaining a pH of 7.2 to 7.6 is the optimum range, with a chlorine level of 3.0 ppm to 5.0 ppm. Water temperature does have some effect on the equilibrium. This chart is for water at 86 degrees Fahrenheit. Some … Web1. The best disinfection occurs at lower pH. 2. If you have high alkalinity and high pH (> 8) consider longer chlorine contact time due to reduced efficiency of the hypochlorite form. …

WebDec 13, 2013 · The dissociated hypochlorite ion (OCl-) predominates at higher pH values, above 7.5, while the undissociated hypochlorous acid (HOCl) predominates at lower pH values. At pH 5, nearly all the chlorine is present as HOCl, while a pH value of 10 drives nearly all the chlorine to be present as OCl- (see Figure 1). WebMar 6, 2016 · NaOCl, 5.25%, showed higher pH compared with 5.25% Ca (OCl)2. NaOCl and Ca (OCl)2 in 0.5% and 1% concentrations tend to show a reduced pH level, … framework classes diagnostics

WebJan 27, 2024 · Adding either sodium hypochlorite or calcium hypochlorite will increase pH, while adding chlorine gas will decrease pH. After adding commercial chlorine, adjust the pH of the water to 7 by adding either acid or base. Muriatic (HCl) or citric acid are commonly used to lower pH while sodium hydroxide (lye) will raise pH. Websolid (calcium hypochlorite/Ca(ClO) 2), and gas (Cl 2). 1. Sodium hypochlorite: NaOCl, the liquid form of chlorine, is commonly known as liquid bleach. In a small to medium size water system, sodium hypochlorite is often the disinfectant of choice because of its ease of use and lower health hazard. It is easier to use WebOCl-. The higher the pH level the greater the percent of OCl and the more chlorine required to achieve disinfection. Hypochlorites (OCl-) Usually, sodium hypochlorite (NaOCl) is used, rather than calcium hypochlorite [Ca(OCl)2], because calcium hypochlorite is more costly, causes calcium sludge, and is more dangerous to handle. 1.1.1 1.1.2 1.2. ... framework clinic tillicoultry
