Process characterization and pretreatment of container and drum cleaning industry wastewater using a heat‐activated persulfate oxidation process

The aim of this study was to treat wastewater from washing, cutting or crushing intermediate bulk containers (IBCs), steel drums and plastic drums, using the sulfate radical-based oxidation method. In study, it planned make suitable for activated sludge treatment by applying neutralization after a process. Samples were taken industry three times these processes. To determine optimum conditions in chemical oxygen demand (COD), removal efficiency calculated, temperature, time, persulfate dose determined. Since washing is done with hot water industry, thermal activation method used persulfate. results COD efficiency, total organic carbon (TOC), biochemical (BOD), nitrogen (TN), phosphorus (TP), potentially toxic metal(s) measured samples. According temperature at which best observed 70°C, COD/S2O82− ratio 1:2, contact time 5 h. As result has been revealed that such can be given same existing reactor instead FeCl3
