Abstract:
A system for continuously removing arsenic from arsenic-contaminated water comprising:a plurality ranging from 10 to 25 of immobile vessels, each containing a resin bed capable of binding arsenic from said contaminated water and yielding purified water and a arsenic-contaminated resin bed; a plurality of electronically controlled valves fitted to each one of the immobile vessels, one of said valves admitting arsenic-contaminated water to the vessel, one removing purified water, one admitting regenerant, one admitting rinse liquid and one or more removing regenerant and/or rinse liquid; and an electrical controller directing the plurality of electrically controlled valves so that when the system is in operation continuously removing arsenic, contaminated water is flowed to a subset of vessels, regenerant is flowed to a subset of vessels containing the most highly arsenic-contaminated resin bed and rinse liquid is flowed to a subset of vessels containing the least arsenic-contaminated resin bed.
