good bleaching and oxidation disinfectant water treatment
Chlorine Dioxide (ClO2); advantages & disadvantages in the
As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in water treatment and in bleaching. The use of chlorine dioxide for pre-disinfection and oxidation of drinking water has increased significantly over the past 20 years.

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.

Oxidation and disinfection using chlorine - Sources
The commercial water-based solution is known as "bleach", a greenish-yellow liquid that has a pH of between 11.5 and 13. The industrial strength solution has a concentration of 47 to 50° chlorometric corresponding to 149-159 g · L –1 of active chlorine. Household bleach has a concentration of approximately 15° chlorometric (47.5 g · L –1 of active chlorine).

Advanced oxidation process
Advanced oxidation processes (abbreviation: AOPs), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and wastewater by oxidation through reactions with hydroxyl radicals (·OH). In real-world applications of wastewater treatment, however, this term usually refers more specifically to a subset of such chemical ...
