Application of ozone in waste water treatment includes the destruction or removal of: complex organic molecules, cyanides and phenols from chemical waste, etc.. In addition, subjecting municipal waste waters or combined municipal waste waters or combined municipal industrial waste waters to a final ozone process enables reuse for applications such as wash-water, irrigation, or fire fighting systems. Ozone is also used extensively in industry in oxidation processes and for disinfection purposes.
Wastewater discharges from industrial sources contain a wide range in levels of COD, BOD, TSS and other emerging contaminants (i.e. pharmaceuticals, aldehydes, glycol, amines, alcohols, complex proteins, etc), that can be effectively removed with ease, using Ozone as the disinfectant.
