Abstract
In the purpose of this study, we investigate the characteristics of the pilot-scale wastewater treatment system applied to BAF, MBR and IPNR as examining the removal efficiency of organic pollutants and operating factors in small decentralized wastewater treatment systems, and operating factors. For long-term operation period of more than nine months, pilot-scale plant operating results appeared very stable. This results were the removal efficiency of BOD was 80.3% above and removal efficiency of COD with an average of about 91.0%, satisfied the final effluent water quality standards. TN in the final effluents was the average concentration of 7.9 mg/L, was satisfactory water quality standards 10 mg/L of TN.
