Wet Oxidation Process

Organic Waste Decomposing Process

Spent resins (bead and powdered), filter sludge and so on are difficult to decompose. In addition, conventional treatment technologies such as incineration and/or solidification pose further drawbacks in off-gas treatment and solidified waste qualities. JGC's Wet Oxidation process overcomes these problems and reduces waste volume by decomposing their organic structure to CO2 and H2O using H2O2 oxidation reaction. This process provides technical and economical advantages. This process also applies to hazardous organic wastes.
