For example: To achieve 5 mg/L chlorine in a 1000 litre tank, add approximately 40 mL of 12.5% sodium hypochlorite. By removing suspended solids to nearly undetectable levels, the rate of decomposition is significantly reduced. The Use 1 part bleach to 99 parts cold tap water (1:100 dilution) for This website uses cookies to improve your experience while you navigate through the website. Sodium hypochlorite can also be made by dissolving salt in softened water, then electrolyzing the solution. When salt is dissolved in softened water, a brine is created; then, when the solution is electrolyzed, the brine forms a sodium hypochlorite solution and hydrogen gas. The solution is This decomposition produces oxygen. hb```b``c`e``f@ aw O|R }CqYodvCFoC -A=K5=/6)h`V6d\;A&HdF>K%t!,9T8[mg6l46s4 Ii!4 0 Chemical Blending & Chemical Dilution Systems, Sodium Hypochlorite High Strength Low Salt FAQ.
