Stacked High-quality Ultrapure Water Reverse Osmosis EDI Module For Water Treatment
MK-7 is designed to
• Provide ultrapure water for industrial applications including power 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 recirculation, simplifying system design.
description and use
MK-7 are high flow electrodeionization (EDI) stacks which use electrical current to deionize and polish reverse osmosis (RO) permeate water. MK-7 product water is at an ultrapure level required in today’s most demanding applications.
