water treatment - the oxidants and disinfectants - Degremont®

oygen. Oxygen is one of the most abundant elements found in Nature. In its molecular form O 2, oxygen or "dioxygen" is a colourless gas that is relatively insoluble in water (see characteristic constants of gases).. As demonstrated by the oxidation reduction equations, the oxidising capacity of oxygen is heavily dependant on pH and low compared to other oxidants used.
