Wastewater that contains high organic material is being produced during cajuput oil production. Appropriate treatments, therefore, are required in order to meet the effluent disposal standard. Coagulation and neutralization as pre-treatments prior to anaerobic filtration were applied to such wastewater sample. The result showed that both pre-treatments were able to reduce the total suspended solid by 73% and increase the pH by 6. The anaerobic filtration prototype, with 3-stage filtration process, was able to reduce the levels of BOD, COD and TSS of the wastewater by 39.34 + 1.61 mg/l; 67.73 + 0.00 mg/l; and 7.20 + 0.23 mg/l, respectively. |
