Guwahati, Aug. 25 -- The Indian Institute of Technology (IIT) Guwahati researchers have developed a water-treatment technology that can remove arsenic and fluoride simultaneously from contaminated groundwater. This could be a vital contribution towards ensuring safer and affordable drinking water in regions affected by naturally occurring groundwater pollution.

The researchers from IIT Guwahati developed a rotating-anode electrocoagulation (RA-EC) reactor that achieved up to 98.2% arsenate and 91.8% fluoride removal within minutes. The initial demonstration was performed at an estimated operating cost of Rs 18 to Rs 58 per 1,000 litres of treated water, depending on contaminant concentration, a release said.

The findings suggest that th...
