Electrodialysis Reversal (EDR)

GE's electrodialysis reversal systems, pioneered by Ionics, suit multiple applications, including:

  • Reducing radium, arsenic, perchlorate, fluoride, nitrate, hardness, uranium and selenium in drinking water

  • Recycling municipal and industrial wastewater

  • Recovering reverse osmosis reject

  • Desalting well and surface waters

  • Desalting water for boiler makeup and other industrial uses

Features & Benefits

Benefits To You

  • High water recovery design efficiently processes a source water and generates low concentrate volume for disposal.

  • Rugged systems are less sensitive than reverse osmosis (RO) to particulates and metal oxides.

  • Long membrane life (typically 10 years) lowers the cost of ownership.

  • Chlorine-resistant membranes are tolerant to disinfection, allowing use on challenging waters.

  • Wastewater reclamation reduces waste discharges and water use charges.

  • Easy to control salt removal and product quality by adjusting amount of electricity applied to membrane stack.
