An improved process for water treatment to remove Arsenic, Iron and phosphate

Arsenic removal filter developed at IIT Bombay (IITB Product) involves the cooxidation of Fe(II) and As(III) in the presence of dissolved oxygen and subsequent arsenic removal by hydrous ferric oxide, which is formed from oxidation of Fe(II) naturally present in groundwater and from leaching of iron nails, thus As(III) oxidation is achieved without addition of any chemicals. This filter can be fabricated by local plumbers and masons in field using locally available materials. The unit is cost-effective and robust, does not require extensive monitoring.
