Abstract
Arsenic (As) contamination of groundwater has become problem in the world. Although arsenic removal by sand filtration can be used in various area of the world due to the low cost and easiness for maintenance and control, it have not been established how to use sand filtration effectively for arsenic removal. In this study, the groundwater contaminated by arsenic was reproduced by microbiological redox mechanism at first.Second, the reductive water with arsenic(III) was permeated through the column filled with dry sand while changing a condition for verifying performance of arsenic removal. This study showed the effective way of arsenic removal by sand filtration and one of the solution for problem of arsenic contamination of groundwater for drinking.
