Advance Oxidation Process

Advanced oxidation processes (AOPs), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials from water and waste water by oxidation through reactions with hydroxyl radicals (·OH). This term usually refers more specifically to a subset of chemical processes that employ hydrogen peroxide (H2O2), ozone (O3), and/or UV light. 

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

We have successfully installed effluent treatment plants using AOPs for bulk drugs, pharma formulation and chemical industries.
