This study was carried out to get efficient of organic material removal and wastage sludge production minimized effects on the treatment of Brewhouse wastewater using aerobic RBC and curtain biological film contact process. As a results of biofilm attachment experiment aggravation of water quality due to excessive biofilm showed after every 13 days of operating times. The concentration of BOD at raw wastewater was 3800${sim}$5300 mg/L and COD was 2300${sim}$3100 mg/L. The average BOD of effluent was maintained 18 mg/L and average COD was 26 mg/L. The result of this experiment was wastage sludge did not almost generated.
