| description abstract | Iron-coated granular activated carbon (Fe-GAC) was proven to be effective for removing selenite from aqueous solution in batch studies. Design and use of the adsorbent in column settings requires understanding the key mass transfer characteristics for full-scale applications. In this study, rapid small-scale column tests (RSSCTs) were conducted at various empty bed contact times (EBCTs). A pore and surface diffusion model (PSDM) was introduced to predict selenite breakthrough curves of continuous flow packed columns containing Fe-GAC. Effluent Se(IV) breakthrough occurred immediately in the experiment with 0.055-min EBCT. The column reactor was found to treat approximately 780 bed volumes of water containing | |
