Recently, advance oxidation technologies have been demonstrated to remove various potentially harmful compounds that could not be effectively removed by conventional treatment processes.

The Advance oxidation Processes so call AOP, using the combination of ozone and ultraviolet light hold great promise to provide alternates for better protection of the public health and water environment.

AOP is ambient temperature processes involving the formation of strong oxidation I.e. hydroxyl radicals in water or an aqueous solution.

The Hydroxyl radical, is know very aggressive and almost indiscriminately attack all type of in organic and organic pollutants found in wastewater.
