| Abstract |
| The objective of this study is to investigate the influence of water temperature and aeration strength on membrane filtration of small-scale membrane bioreactor (MBR) with the treatment capacity of 100 m3/d, which consisted of anaerobic, anoxic, and aeration tank coupled with membrane. Experiments were conducted with real MBR system using real wastewater. Applied transmemrane pressure (TMP) was <0.5 kgf/cm2.h. Influent concentrations of real wastewater were in the range of BOD <100 mg/L, COD <70 mg/L, SS <105 mg/L, T-N <23 mg/L, T-P <3 mg/L, E-coli <110,000 no/mL, MLSS < 5,000 mg/L, respectively. As a result, the increase of both water temperature and aeration strength decreased TMP of MBR system. The efficiency of MBR system achieved the high removal for organic and particulate with removal efficiencies of >92%, while it achieved a relative low removal for nutrients with removal efficiencies of <53%. |
