WebChlorine is available in a number of different forms: Pure elemental gaseous chlorine: a greenish-yellow gas with a pungent and irritating odor that is heavier than air, … WebChloramination sometimes replaces chlorination to accomplish more reliable disinfection, because it can reduce the likelihood of formation of certain disinfection byproducts (DBPs) and provides a longer-lasting residual in distribution systems. Chlorination typically refers to application of chlorine to achieve a residual of free chlorine.
WebThe breakpoint chlorination dose is the dose of chlorine that satisfies all chloride demand of water so that further addition of chlorine will result only in an increase in free residual chlorine. The safe dosage of chlorine is 1–2 mg/L but during an outbreak of any epidemic it has to be increased by several fold (e.g., 10–15 mg/L) and is ...
