Advanced Oxidation Process

Advanced Oxidation Processes (abbreviation: AOP), refers to a set of chemical treatment procedures designed to remove organic and inorganic materials in waste water by oxidation.

Contaminants are oxidized by pulsing and cycling through four different reagents: ozone, hydrogen peroxide, oxygen, and air, in precise, pre-programmed dosages, sequences, and combinations. These procedures may also be combined with UV irradiation. This results in the development of hydroxyl radicals.

The AOP procedure is particularly useful for cleaning biologically toxic or non-degradable materials such as pesticides, petroleum constituents, and volatile organic compounds in waste water. The contaminant materials are converted to a large extent into stable inorganic compounds such as water, carbon dioxide and salts. A goal of the waste water purification by means of AOP procedures is the reduction of the chemical contaminants to such an extent that the cleaned waste water may be reintroduced into receiving streams.
