High-efficiency liquid-phase oxidation reaction process is used effectively for treating wastewater with intermediate/low concentration of COD components. The system requires no application for the Waste Management and Public Cleansing Law as no fuel is used to treat wastewater under increased temperature and pressure. Combined with the catalytic technology from Nippon Shokubai Co., Ltd., the system achieves further space and energy savings.
Features
・Combustion is not applied, requiring no fuel, and exhaust gas does not include NOx, SOx, and dioxins.
・No secondary waste such as excess sludge as in biotreatment is generated. The system is applied to wastewater that is difficult to handle through biotreatment.

Detoxifying COD components in Effluent water by catalyst with high-efficiency liquid phase oxidation reaction WAO is a high-efficiency liquid-phase oxidation reaction process developed under technical license from Nippon Shokubai Co., Ltd. High running costs were a drawback for conventional combustion treatment. With WAO, a solid catalyst performs efficient liquid-phase oxidation and decomposition of COD components such as organic, nitrogen and sulfuric compounds in effluent water, at high temperature and high pressure. WAO not only exhibits high performance for persistent cases that are difficult with biological treatment, but is effective for treating effluent water with much inorganic COD components as well.
Saves energy as fuel is not required
Decreases environmental load as NOx SOx and dioxins are not included in exhaust gas
No application is required to install WAO in relation to Waste Disposal Law
No generation of secondary waste such as organic sludge typically associated in biological treatment
Running cost is 2/3 or less and footprint is 1/3 or less
・Advanced treatment recycles treated effluent as service water
・No secondary pollution as catalyst itself is non-toxic
・Treats wastewater that is difficult to treat biologically
・Exhaust gas contains no NOx, SOx or dioxins
・Treats 10~500 ton/day of compounds
・Applies for decolorization
