Reverse osmosis filtration(RO) system and ultrafiltration(UF) system are principally used for domestic home drinking water treatment systems. The object of this study is to make a comparison between two systems in terms of their abilities to remove RNA coliphage Qβ as an indicator of pathogenic enteroviruses. The virus removal ratio of RO system was 99.999%, which was higher than EPA virus treatment guideline(99.99%). In the course of filtration, removal ratios of sediment filter, pre-carbon filter, reverse osmosis membrane and post-carbon filter were 75.000%, 93.208%, 99.997% and 99.999%, respectively. In case of UF system, virus removal ratio was 99.708%. Removal ratios of sediment filter, pre-carbon filter, post-carbon filter and ultrafiltration membrane were 71.038%, 91.530%, 98.283% and 99.708%, respectively, in UF steps. Therefore, RO system is more effective than UF system in virus removal.
