This study was carried out to obtain basic parameters for simultaneous removal of nitrogen and organic matter using Moving Media Complete Mixing Activated Sludge (MMCMAS) system with intermittent aeration method. Lab-scale MMCMAS reactor was operated under the variations of organic loading rate and oxic/anoxic time ratio. The organic loading rates were varied at 1, 3, 5 and 7g BODlm3.d respectively. Soluble Chemical Oxygen Demand (SCOD) and Soluble Biological Oxygen Demand (SBOD) removal efficiencies were found to be 87%, 4, and 95% respectively, and no  relationship between organic removal and oxic/anoxic time ratio was observed. Nitrogen remova1 efficiencies ranging from 76% to 89%, varied widely by oxic/anoxic time ratio. The nitrogen removal was increased by increasing anoxic and oxic time for the organic loading rate below 5 g BOD/m3. d and 7g BOD/m'. d, respectively. Sludge production of MMCMAS system with intermittent aeration was 0.16 to 0.36 (g VSS/g BOD removal) averaging 0.27 (g VSSlg BOD removal). This value is relatively lower than the value obtained previously in MMCMAS system with continuous aeration which was 0.38 (g VSS/g BOD removal).
