Patent ID: 8034244

Claim:
A system for continuously removing arsenic contaminants from arsenic contaminated water comprising: a plurality of immobile vessels, each containing a resin bed capable of binding arsenic contaminants from said arsenic contaminated water and yielding purified water and an 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 contaminants, 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.
