EDI/EDR Systems

Description and Use

Electrodeionization (EDI) stacks which use electrical current to de-ionize and polish reverse osmosis (RO) permeate water. The EDI water product is at an Ultrapure level required in today’s most demanding applications.


Electrodeionization (EDI) Product 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 mixed bed resin within the stack.
  • Be leak free, guaranteed.
  • Eliminate brine injection and concentrate recirculation, simplifying system design.


Typical Applications

  • Semiconductor
  • Microelectronics
  • Power Generation (NOx, Boiler Feed)
  • General Industry
  • Quality Assurance
  • CE, UL & CSA marked


Reverse Osmosis membranes

  • High salt rejection
  • Low energy
  • High energy
  • Brackish water
  • Sea water
  • High saline water
  • Ultrafiltration membrane
  • Nanofiltration membrane


Cartridge filters

Cartridge family is a 100% pure polypropylene depth filter (including adapters) with exceptional dirt-holding capacity, Its true-graded density filter matrix (lower density at the surface of the filter with progressively higher density toward the center) captures particles throughout the entire filter depth. This translates to longer life and fewer change-outs than existing string-wound or resin-bonded filters.
