한외여과막의 모듈형태에 따른 하수처리장 방류수의 처리 효과

A Study on the Removal Effect of Sewage Treatment Effluent by Ultrafilter Membrane Species

This study has designed to investigate the removal effect of sewage treatment effluent by ultrafilter membrane species and then to analyze the change of pH, bacteria and E. coli., the concentration of chlorides. Ultra filtration process did not effective to remove chloride, Ca and Mg. Spiral type ultrafiltration process was more effective to remove chemical oxygen demand of sewage treatment effluent than Hollow type ultrafiltration process. The flux of spiral wound ultrafilter was higher than the hollow fiber ultrafilter.
