| Abstract: | In the present invention there is provided an electrochemical device for removing arsenic from water which consists of a three stage electrochemical reactor equipped with a plurality of both stable and soluble electrodes. The combination of electrodes can simultaneously oxidize the arsenite present in the contaminated water and generate an adsorbent in-situ on which arsenic is adsorbed and removed from water. Stable electrodes such as titanium metal coated with oxides of Ru/Tn/lr are fitted in the first chamber, whereas both stable and soluble electrodes are placed in the second chamber and the third chamber is fitted with only soluble electrodes. The treated water can be further passed through known filter, activated carbon and UV-lighting to remove suspended solids, dissolved organics and pathogenic bacteria. | ||
