In this paper, the Nepali bio sand filter (BSF) was modi-fied with different bio-adsorbents, and proved to be an efficient method for arsenic removal from groundwater. Three dif-ferent bio-adsorbents were used to modify the Nepali BSF. Iron nails and biochar BSF, ~96% and ~93% arsenic removal was achieved, within the range of WHO guidelines. In iron nails, BSF and biochar BSF ~15 dm3∙h–1 arsenic content water was treated. In the other two BSFs, rice-husk and banana peel were used, the arsenic removal efficiency was ~83% of both BSFs. Furthermore, the efficiency of rice-husk and banana peel BSFs can be increased by increasing the surface area of the adsorbent or by reducing the flow rate.}, type={Article}, title={Arsenic removal through bio sand filter using different bio-adsorbents}, URL={http://www.journals.pan.pl/Content/119043/PDF/Keerio%20et%20al%20744.pdf}, doi={10.24425/jwld.2021.136141}, keywords={arsenic, banana peel, bio-adsorbent, bio-sand filter, biochar, rice-husk, water treatment}, }
