        This study was carried out to investigate the filtration characteristics of membrane modules according to hollow fiber dispersion for direct solid-liquid separation of activated sludge. 2 bundle, 4 bundle, and 10 bundle module used in this experiment according to hollow fiber dispersion was manufactured at laboratory and permeate flux and transmembrane pressure(TMP) of each module were observed under a suction pressure of 0.5㎏f/㎠. As the hollow fibers were dispersed, permeate flux was increased and TMP was decreased. Permeate flux and TMP of each module was 15.0 ℓ/㎡·h and 31.8 ㎝Hg for 2 bundle, 16.0 ℓ/㎡·h and 17.4 ㎝Hg for 4 bundle, and 20.4 ℓ/㎡·h and 13.8 ㎝Hg for 10 bundle. In conclusion, the membrane fouling is expected to be decrease by maintaining lower TMP with hollow fiber dispersion.
