The objective of this study is to evaluate the possibility to apply pre-ozone and membrane system for drinking water. This system is improved in fouling control by pre-ozone system. It is composed of ultrafiltration hollow fiber type membrane and ozone reactor. The result of this study is that the flux is increased about 10.7% and decreased in TMP by the pre-ozone. Also, backwashing pressure decreased about 18%. The optimum concentration of residual ozone is 0.3~0.5 ppm. During the period, the recovery ratio of this system was turned out to be 90% as the flowrate of effluent is $67.1m^3/day$. When the TMP and backwashing pressure was $0.85kg/cm^2$ and $1.10kg/cm^2$, this system was stable without sudden fouling. Finally, the quality of effluent is satisfied the guidelines for potable water quality such as turbidity, color, E.coli, Mn, Al, Fe and so on.
