Electro Dialysis Reversal (EDR)

Electro Dialysis Reversal (EDR)

Electro Dialysis Reversal (EDR) is a desalination process for complex wastewater treatment. EDR’s key strengths include:

  • Membranes rejecting organic contaminants
  • Resistance to chlorine and chemicals
  • Enhanced cleaning with aggressive chemicals
  • Robust performance on challenging streams
  • Higher salt concentration tolerance


EDR’s notable benefits:

  • High water recovery
  • Minimal impact from silicates
  • Reduced need for chemical cleaning
  • Extended membrane lifespan and low energy consumption

Our solution ensures stable operation, durable equipment, easy maintenance, space efficiency, and expandability.

EDR is the perfect choice for applications such as cooling towers blowdown treatment, petrochemical plant effluent treatment, mining wastewater recovery, and brine “squeezing” in desalination.

EDR's key strengths include:

Energy-efficient process for Near ZLD applications
Capable of tolerating streams with high organic content
High operational capability at extreme salinity levels
Reject salinity can reach 150,000 – 200,000 ppm as TDS
Ability to withstand harsh chemical cleanings
Dissolved silica in water does not impact Electro-dialysis

EDR’s notable benefits:

Cost-efficient for high salinity operations
No osmotic pressure limitations (unlike RO systems)
Achieves very high recovery ratios
More efficient cleaning compared to RO
High tolerance for Chlorine levels in treated/cleaning water
Enables high recoveries even with high silica concentrations in raw water

Additional Products

AGAR® RF

The AGAR® RF (Roughing Filter) MBBR is a two-stage biological system consisting of a small volume AGAR® MBBR reactor followed by an activated sludge system.

GenDesal

Proven desalination solutions combat water scarcity and global warming, efficiently converting sea and brackish water to potable water, while reducing environmental impact.

MBDEN

Nitrate contamination in groundwater, primarily stemming from the widespread use of fertilizers in rural areas, poses a significant concern for public health, with links to conditions such as methemoglobinemia, commonly known as "blue baby" disease, and potential carcinogenic effects as per recent research findings.

AGAR® MPU

The AGAR® MPU units are innovative prefabricated solutions for the treatment of Gray or Black water for several hundred people, with a maximum capacity of 70m3/d.
