How does the advanced oxidation process (AOP) work?

The advanced oxidation process removes contaminants in water and wastewater by oxidation through reactions with highly reactive hydroxyl radicals (.OH). This chemical process uses ozone (O3), hydrogen peroxide (H2O2), and/or UV light.

How effectively does it reduce the concentration of contaminants?

AOP has the capability of reducing the concentration of contaminants from several-hundred ppm to less than 5 ppb. By using the strongest oxidants, AOP can efficiently oxidize essentially any contaminant in water at a diffusion controlled reaction speed. Contaminants are rapidly converted into tiny inorganic molecules.
