In this study, the effects of the pretreatment method and the dispersion of hollow fiber membranes on the permeate flux were investigated. As the ethanol (as solvent) concentration increased from 10 to 90 %, the permeation rate through the polysulfone membrane increased. The permeate flux was constant at concentrations greater than 20 %. A relatively high flux was obtained at moderately low pressures and the pressure increase rate decreased with the dispersion of the membrane. As a packing density decreased, the permeate flux increased, resulting in low pressure. The maximum permeate flux (30.08 threads/cm2) was achieved under stable conditions after 4 days’ separation. On the other hand, the operation conditions were determined in a submerged membrane bio-reactor using dispersed hollow fiber membranes. From permeate flux measurements according to the packing density, we found that 20 membrane modules showed a stable and high flux. The growth and decay coefficients of microorganisms were 0.6464 and 0.0712, respectively. From the data analysis, we determined that the most efficient conditions for long-term operation were an MLSS concentration within the range from 3800 to 8200 mg/L and organic compound loadings from 300 to 600 mg/L.
