This study evaluated the feasibility of using anaerobic pre-treatment before aerobic polishing treatment for high-strength industrial wastewater (BOD values ranging form 200 to 5000 mg/L). The results indicated an economic feasibility at water strengths above 1000 mg/L, but treatability evaluation would be required for every specific industrial wastewater to confirm the technical feasibility.
