Electrodialysis Reversal Water Treatment

Recover more from your high total suspended solids (TSS) and high silica source water

If your source water is challenging due to high total suspended solids (TSS) or high silica, electrodialysis reversal (EDR) for drinking water can provide high water recovery, reducing the strain in water scarce areas.

Because of the polarity reversal design, EDR for wastewater reuse is a self-cleaning, durable membrane system ideal for turbid wastewater. EDR technology achieves high water recovery for water scarce areas and SUEZ’s wastewater EDR systems reclaim more than 20 million gallons per day (75,000 m3/day) of wastewater for other uses.

What is the Electrodialysis Process?

For brackish water or wastewater with moderate concentrations of dissolved ions, electrodialysis, or EDR, is an excellent option to achieving superior treated water quality. Electrodialysis is an advanced membrane technology process that utilizes ion movement to desalinate water. EDR systems are rugged, with very long membrane life and require significantly less pretreatment than spiral wound membranes while having the ability to achieve very high water recoveries.

EDR Product Features

  • High water recovery design efficiently processes source water and generates low concentrate volume for disposal
  • Rugged systems are less sensitive than reverse osmosis (RO) to particulates and metal oxides
  • Targets arsenic, fluoride, radium and nitrate removal for potable water applications
  • Long membrane life (typically 20+ years for potable water installations) for a lower cost of ownership
  • Chlorine-resistant membranes are tolerant to disinfection, allowing use on challenging waters
  • Wastewater reclamation reduces waste discharges and water use charges
  • Effectively treats rejects and blowdowns
  • Easy to control salt removal and product quality by adjusting amount of electricity applied to membrane stack
