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.

FlexEDR 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.

FlexEDR 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.

Ultra-High Recovery at Full-Scale: RO and EDR Plants Shipped

October 20, 2021

Saltworks is excited to announce the shipment of two ”competing” membrane-based industrial wastewater treatment plants. Although electrodialysis reversal (EDR) and reverse osmosis (RO) may be viewed as competing desalination technologies, Saltworks offers both and helps clients navigate the fit case for each.
