Hybrid System For Selective Removal Of Contaminants

摘要

A system for removing contaminants from water utilizes a layered stack of anion permeable membranes and cation permeable membranes positioned between an anode and a cathode. The layered stack of membranes forms a concentrate water stream flow channel and a diluent water stream flow channel. Ion specific ion exchange resins are inserted within the diluent water stream flow channel. The water stream is pumped through the layered stack of anion permeable membranes. By using the anode, the cathode, and the voltage source to place an electrical potential gradient across the layered stack of membranes the negative ions are drawn toward the anode and the positive ions are drawn toward the cathode in the diluent water stream that flows through the diluent water stream flow channel.
