Abstract

The feasibility of selenium removal from drainage water by slow sand filtration (SSF) was investigated. Two anaerobic laboratory-scale slow sand filters, operated in parallel, received synthetic feed solution. Selenate reduction and subsequent selenium removal were monitored during five experimental filtrations. The results suggest that selenium removal occurred by the dissimilatory reduction of selenate to elemental selenium. This reduction was independent of sulfate. Selenium removal efficiencies were governed by the hydraulic loading rate (HLR).
