Abstract
This design manual presents the steps required to design and operate a water treatment plant for removal of arsenic (As) from drinking water supplies using iron removal processes. It also discusses the capital and operating costs, including the many variables that can raise or lower costs for identical treatment systems. Iron removal processes are generally simple, reliable, and cost-effective. Arsenic removal is accomplished by adsorption of As(V) onto ferric hydroxides formed in the iron removal process. Several iron removal treatment methods can remove arsenic from drinking water supplies to levels below the new arsenic maximum contaminant level (MCL) of 0.010 mg/L; these methods include oxidation and filtration, and the use of solid oxidizing media products and manganese greensand. Many existing water utilities have much if not all of the appropriate technology in place for iron removal, but may need to modify or adjust the processes in order to meet the new MCL.
