Water and Effluent Treatment
Hydrogen sulphide control
Sewage frequently has to be pumped over long distances. Anaerobic conditions can then develop in the sewer system leading to the production of hydrogen sulphide(H2S) with consequent odour and corrosion problems. Injection of Hydrogen Peroxide into the sewer can both eliminate any sulphide already developed and maintain aerobic conditions, thus preventing further sulphide formation.
Detoxification of industrial waste waters
Hydrogen Peroxide provides an effective means of treating certain toxic industrial pollutants such as cyanides, phenols, nitrites and sulphides. For example, waste water encountered in refinery, chemical or pharmaceutical operations can be treated with Hydrogen Peroxide. Oxidation processes have been developed in which Hydrogen Peroxide is catalysed in various ways according to the nature of the pollutant present, thus achieving detoxification in the most effective manner.
Oxygenation
As a potential source of oxygen, Hydrogen Peroxide is used in biological treatment, particularly at times of overload, for the treatment of bulking sludges, and for the prevention of denitrification in settling tanks.
