This study shows that integrating EM4 with aerobic and anaerobic biofilters dramatically reduces pollutant levels in tofu industry wastewater, implying regulatory compliance.
Key Points
An integrated treatment system reduced COD by 86%, achieving final concentrations of 2.4 mg/L.
The wastewater treatment used EM4, anaerobic digesters, and aerobic biofilters to meet environmental standards.
Implementation estimated at IDR 1,177,378,400 with monthly operating costs confirming economic feasibility for small enterprises.
Further optimization of wastewater management through land assessment is recommended for sustainability.
