The quantity of sodium hypochlorite needed for water treatment method is a lot less than another two types of chlorine, with 0.two-two mg of NaOCl/L of water becoming advisable. Like calcium hypochlorite, sodium hypochlorite may even develop a hypochlorite ion, but as opposed to calcium ions, sodium ions are produced.
