high pure white poly aluminium chloride for water making process
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 ozone – ozone applications
The CT values to be maintained depend on the purpose of the disinfection. It is accepted that the drinking water treatment conditions defined in 1964, i.e. 0.4 mg · L –1 of residual ozone for a 4 minutes contact time (CT = 1.6 mg · min · L –1) will meet the target of 2.5 log Giardia lamblia cyst elimination at 5°C. The most advanced studies tend to demonstrate that a one log
