Precipitation separation as metal hydroxides is possible! The decomposition process of residual hydrogen peroxide is unnecessary.
One of the wastewater treatment methods is the Fenton treatment process, which is commonly used in a systematized form. By adding a special catalyst called "Kotalist PB," the treatment efficiency can be significantly improved. It is now possible to decompose difficult-to-degrade COD and TOC that were previously challenging. Since the amount of iron salt (FeSO4·7H2O) used can be reduced, the resulting sludge is greatly minimized. 【Advantages】 ■ Capable of decomposing difficult-to-degrade COD and TOC ■ Precipitation separation as metal hydroxides is possible ■ Decomposition rate is significantly improved compared to conventional Fenton treatment ■ No need for a decomposition process for residual hydrogen peroxide ■ Can be used with only minor modifications to existing equipment *For more details, please refer to the PDF document or feel free to contact us.

Company information
OES Corporation aims to reduce CO2 emissions and achieve "zero" processing energy through energy recovery and reuse. After being used in various industries such as semiconductors, steelmaking, power generation, and pharmaceuticals, nitrogen-containing wastewater, including ammonia, is discharged. Treatment of this wastewater is essential and strictly regulated. Therefore, not only is it important to comply with environmental standards, but also to eliminate unnecessary energy consumption, which leads to cost savings. At OES, we utilize our unique catalytic technology to convert ammonia into non-polluting nitrogen (N2) during the treatment process, suppress the generation of nitrogen oxides (NOx), reduce CO2 emissions through energy recovery and reuse, lower running costs through energy conservation, and avoid generating secondary waste that would become industrial waste, thereby contributing to an energy-efficient society and environment.
