Ultra Pure Water Reverse Osmosis EDI Membrane Stack Electro-Deionization (EDI/CEDI) Water Filtration Systems
Ultra Pure Water Reverse Osmosis EDI Membrane Stack Electro-Deionization (EDI/CEDI) Water Filtration Systems
E-Cell MK-3 is designed to:
• Provide Ultrapure Water for industrial applications including Power, Semiconductor, and General Industry.
• Produce Mixed Bed quality water on a continuous basis.
• Require no caustic or acid for regeneration of ion exchange resin within the stack.
• Be leak free, guaranteed.
• Eliminate brine injection and concentrate re-circulation, simplifying system design.
Description and Use
E-Cell MK-3 stacks are electro deionization (EDI) stacks which use electrical current to deionize and polish reverse osmosis (RO) permeate water. The product water for the MK-3 is at an Ultrapure level required in today’s most demanding applications.

Application:
The MK-3 and E-CELL-3X series of e-celledi module is ge-edi module of electrodeionization, which uses current to deionize and polish the produced water of reverse osmosis. The water produced by mk-3 and E-CELL-3X of edi module is ultra pure water, which is suitable for the industries with more stringent water quality requirements.
