Abstract
Submerged filter process that is usually applied to wastewater treatment was tried to remove viruses in raw water for drinking water. E.coli phage Qβ and poliovirus 1 (LSc, 2ab) were treated by the reactor. Batch test using the reactor fully attached by microorganisms showed the reduction of 80-95% of added phage within 5 hours of the retention time.When the phages were added continuously into the reactor, high reduction level which was attained soon after introduction of phages into the reactor could be kept throughout a test.It is suggested from this study that the submerged filter can be used for pretreatment process to remove viruses of drinking water treatment.
