Bleaching Powder: - Bleaching powder is used for small quantities of water due to its action hypochlorous acid (HOCl) and nascent oxygen is produced which are powerful germicides

Ozone: - It is produced by passing silent electric discharge through cold and dry oxygen.Unstable ozone formed breaks down to liberate nascent oxygen produced is a powerful oxidizing agent and oxidizes organic matter present in water and also kills bacteria.

Chlorine: - It is employed directly as gas in form of solution in water. It produces hyprochlorous acid which is a powerful germicide as a result of chemical reaction between enzyme and HOCL, which inactivate the enzyme.
