E-Cell* MK-3 Stack
Industrial Electrodeionization (EDI) Stacks
E-Cell* MK-3 is designed to:
Provide Ultrapure Water for industrial applica-
tions including Power, Semiconductor, and
General Industry.
Produce Mixed Bed quality water on a contin-
uous basis.
Require no caustic or acid for regeneration of
mixed bed resin within the stack.
Be leak free, guaranteed.
Eliminate brine injection and concentrate recircu-
lation, simplifying system design.
Description and Use
MK-3 E-Cell stacks are electrodeionization (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.
