Abstract
In this study, novel nano silver sand filtration method was compared with UV treatment and normal sand filtration method through filtering treated water from sewage treatment plant. As a result, $BOD_5$ removal rate of nano silver sand filtration showed higher approximately 31% and 23%, comparing with UV treatment and sand filtration. Moreover, $KMnO_4$ removal rate of nano silver sand was about 6.6 and 2.8 times higher than other two methods. In addition, it showed better for removing SS and total coliform, comparing with others. Also, there is no bacteria on nano silver sand after experiments. Therefore, nano silver sand filtration will be effective for advanced water treatment.
