This paper analyzed  some pollutants parameter discharged from tofu industries in Banda Aceh. The parameter of BOD, COD, MLSS, PO4-P NH3-N, Turbidity and pH were analyzed based on the standard method for the examination of water and wastewater, approved by the EPA. The COD and BOD of wastewater from tofu processing facilities in Banda Aceh is ranging from 5000-8500 and 3500-4500 mg/L, respectively.
