There are three primary chlorine/chloramine removal methods in water treatment. The most popular ways to remove chlorine from tap water are: Reverse Osmosis. The particular type of chloramine used in drinking water disinfection is called monochloramine which is mixed into water at levels that kill germs but are still safe to drink. During water treatment, chlorine can combine with naturally occurring organic matter in the water to form compounds called disinfection byproducts (DBPs). This is the standard form of chlorination in which chlorine is added to water as it … The choice of the chlorine type to be used often depends on cost , on the available storage option and on the pH conditions required. It is the fastest acting due to the fact that it is pre-dissolved. There are 5 types of Chlorine; Sodium hypochlorite, Lithium hypochlorite, Calcium hypochlorite, Dichlor, and Trichlor. When many people think about water disinfection, chlorine is the first treatment method that comes to mind.
