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 re-circulation, 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.
