Electrodialysis membrane and gasket stack system

A membrane cell stack for purification of liquid mixtures having contaminants dispersed therein in concentrate liquids and/or in dilute liquids, and for deionization of liquid mixtures by passage through said membrane cell stack comprising:

• an electrodialysis cell stack including a plurality of disparate layers being stacked together, said electrodialysis cell stack having a first end and a second end, said plurality of disparate layers being disposed contiguous and having a first outer layer at said first end, and a second outer layer at said second end;
• a support frame having a first outer end proximate said first end of said cell stack, and having a second outer end proximate said second end, with said plurality of disparate layers interdisposed therebetween said first outer end and said second outer end;
• at least two electrodialysis gaskets including a first electrodialysis gasket being positioned at said first outer end, and a second electrodialysis gasket being positioned at said second outer end;
• a cathode electrode plate being positioned proximate and interior of said first electrodialysis gasket being positioned at said first outer end;
• at least one anode electrode plate being positioned proximate and interior of said second electrodialysis gasket being positioned at said second outer layer;
• at least two membrane gaskets including a first membrane gasket being positioned proximate and interior of said cathode electrode plate, and a second membrane gasket being positioned proximate and interior of said anode electrode plate, said first membrane gasket and said second membrane gasket having a central opening therethrough and having a plurality of holes through each opposed end for passage of liquid mixtures therethrough;
• said plurality of disparate layers including:
• an anion membrane having a plurality of holes through each opposed end for passage of liquid mixtures therethrough;
• a first electrodialysis membrane gasket having a central opening therethrough and having a plurality of holes through each opposed end for passage of liquid mixtures therethrough;
• a first turbulence promoter layer being sized to fit proximate said opening within said first electrodialysis membrane gasket;
• a cation membrane having a plurality of holes through each opposed end for passage of liquid mixtures therethrough;
• a second electrodialysis membrane gasket having an opening therethrough and having a plurality of holes through each opposed end for passage of liquid mixtures therethrough;
• and
• a second turbulence promoter layer being sized to fit proximate said opening within said second electrodialysis membrane gasket;
• whereby said plurality of disparate layers being repeated in series, the liquid mixtures being passed through said electrodialysis cell stack;
• connecting means for connection of said plurality of disparate layers within said support frame;
• and
• a voltage being supplied by a voltage supply means, said voltage being applied as a voltage differential between said cathode electrode plate and said anode electrode plate;
• whereby said electrodialysis cell stack including said plurality of disparate layers being repeated as required for purification and deionization of the liquid mixtures being passed therethrough.
