Ozone, when introduced into the atmosphere at low levels is an excellent air purifier. When an ozone molecule contacts a pollutant, it attaches itself to it and changes its molecular structure in most cases to carbon dioxide and hydrogen. By destroying viruses, bacteria and other microbiological contaminants, the source of the odour are eliminated and the odour does not return. Ozone destroys the contaminant molecule; it does not mask it as other methods do. Ozone treats all of the air, not just the air that is pulled into it as do the vast majority of electronic filters that are on the market today.
Sewage water is a type of wastewater, that is produced by municipal or from a small residential compound, it causes a hazard and cannot be disposed of in any other water like river, lake or sea and also it cannot be dumped on any land. The only solution to treat sewage water is Ozone, it plays a vital role in the process of sewage water treatment and a minimal dose of ozone does this job better than a high dosage of chlorine. Ozone treated water is considered environmentally safe for disposal and it can also be recycled for various uses like gardening, flushing, irrigation etc.
Effluent water is a type of industrial wastewater that contains varying BOD and COD which represent organic contamination. This water is toxic and is harmful to the environment and to human beings who may come in contact with it. This water has to be treated to dispose of it environmentally safe. Worldwide many conventional treatment methods are used today employing different technologies for handling different problems in various industries. Ozone has an effective place in the treatment process of this effluent water.
