Study on artificial soil rapid infiltration system for treating restaurant wastewater

In this research, authors have attempted to adapt artificial soil system to treat high-concentration COD restaurant wastewater (RWW). The capability of treatment system is 80 tonnes per day (t/d). After two months of experimental operation and refinement, the system produced the final effluent quality as follows: COD_Cr = 140.1 mg/L, BOD₅ = 99.8 mg/L and SS = 46 mg/L, which greatly reduced the concentration. The study confirmed that the artificial soil rapid infiltration system (ASRIS) could be modified to treat RWW, and also for the decentralized, high-concentration wastewater.
