IonFlux

Ion exchange membrane

IonFlux ion exchange membranes deliver best-in-class performance for electrodialysis and ion separation applications using next-generation polymer chemistry.

Next-Gen Ion Exchange Membranes

Our breakthrough polymer technology delivers best-in-class selectivity, conductivity, chemical and pH tolerance, and mechanical durability. We offer several models to suit your application: anion/cation selective, monovalent ion selective, proton selective, and proton blocking.

 

IonFlux membranes are manufactured in our quality-assured production facility and are offered exclusively in Saltworks’ FlexEDR systems.

Industry-Leading Performance

Saltworks’ IonFlux ion exchange membranes enable advanced separations previously thought impossible such as removing chlorides without removing sulfates, benefiting from:

  • High multivalent ion transference that removes scaling ions for reduced fouling in downstream processes.
  • Resilience in scaling and oily wastewaters with C1–C10 hydrocarbon tolerance.
  • High resistance to oxidizing agents including bleach (up to 1,000 ppm).
  • Stability over pH 0–12 and up to 60°C (140°F).
  • Smooth membrane surface that minimizes fouling and scaling.
  • Mechanical durability—ductile and tear-resistant.

IonFlux Applications

  • Selectively remove ions and dissolved salts.
  • Desalt water with high organics is not suitable for RO or conventional EDR
  • Perform chemical recovery from mine runoff, factory effluent, and other wastewaters.
  • Treat enhanced oil recovery (EOR) produced water.
  • Remove ammonia from wastewater.
  • Eliminate soda ash softening.
