| A lake water as drinking water source has been focused on the quality despite the limitation of the quantity. Different type and intensity of land use have distinct influence on the lake water quality. Degradation of water quality can result from multiple land use activities, including both point and nonpoint sources. In this study, the performances of membrane filtration (MF) using stirred dead end filtration cell on pollutants removal with solids and sediment loading in lake water was assessed. Batch tests were carried out with artificial water using lake water. Applied membrane permeate flux was 0.5 m3/m2.d. Influent concentrations were in the range of turbidity <500NTU, UV254 <0.9cm-1, and dissolved organic carbon (DOC) < 35 mg/L. As a result, the increase of influent turbidity increased transmembrane pressure (TMP) of MF process. MF process achieved the high removal for turbidity with removal efficiencies of >90%, while it achieved a relative low removal for DOC with removal efficiencies of <60%. In particular, the results showed that non-humic substance in DOC influenced on the increase of TMP. |
