Flex EDR

Flex EDR is an advanced electrodialysis reversal (EDR) system, leveraging our next generation ion exchange membranes. It requires less pre-treatment, tolerates oils and organics, selectively removes ions and uses fewer chemicals.

Built For the Most Rugged Applications

  • Built with our robust, highly ductile IonFlux ion exchange membranes.
  • Intelligent automation self-cleans and maintains peak performance.
  • Modular skids for easy deployment and project integration.
  • Less pre-treatment: operate with oils, organics, particles < 20 μm
  • No chemical softening: patented electrode protection blocks hardness out of EDR electrolyte, so you do not need to remove it before treatment.

Flex EDR Organix:
Desalt Organic Wastewater & Produced Water

  • Treat oily wastewaters that swell conventional membranes with our next-generation IonFlux membranes.
  • Reduce the need for complex pre-treatment when you only need to remove salt.
  • Remove more oil and lower consumption of polymers in enhanced oil recovery (EOR) by desalinating produced water.

Flex EDR Selective:
Remove Ions with Game-Changing Selectivity

  • Conventional EDR pulls all ions across ion exchange membranes under an electric field, without membrane pressure differential.
  • Remove specific ions using state-of-the-art ion exchange membranes with 98% monovalent ionic selectivity (i.e. remove lithium, separate chlorides from sulfates).
  • Change brine chemistry without softening to reach the full potential of your RO system and wring out even more freshwater for beneficial reuse.
  • Concentrate brine to low volumes with membranes – territory previously reserved for evaporative systems.

Flex EDR Ammonia:
Biological Culture-Free Ammonia Removal

  • Treat water chemistries that inhibit biological activity, such as saline waters.
  • Removes ammonia from your wastewater for destruction as a nitrogen gas or conversion to ammonium sulfate fertilizer.
