Applications of Ozone In Water Treatment

摘要

A summary is given about applications of ozone in water treatment. Advantageous and disadvantageous reactions of ozone are shown in potable water, surface water, contaminated ground water, cooling water, and industrial effluents and in leachate of landfills. Traditionally ozone is used for disinfection and removal of odour, smell, colour, iron and manganese in drinking water treatment, by what you can save flocculating chemicals, chlorine and activated carbon. Combinations with ozone increase the ratio of BOD/COD in a biological system. Selective degradation reactions are possible with ozone to remove for example surfactants and dyes.
