Abstract | Arsenic, a known carcinogen, finds its way into the water supply systems due to industrial discharges, geothermal activities and agricultural runoffs. The carcinogenic property of arsenic has forced environmental regulatory agencies around the world to review their maximum acceptable concentration (MAC) in drinking water supplies, one of the main sources of human intake. With stricter regulations likely to be in place, it is necessary to review the treatment processes adopted for the removal of arsenic and identify a suitable treatment technique, which is efficient and economical, for reducing the concentration below the MAC. This paper presents a review of the treatment techniques being employed for the removal of arsenic from water supplies. These include: coagulation; lime softening; activated alumina (AA) systems; adsorption; ion exchange; reverse osmosis (RO); and filtration. |
