Next-Gen Ion Exchange Membranes

Our breakthrough polymer technology delivers best-in-class selectivity, conductivity, chemical & 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 offered exclusively in Saltworks’ FlexEDR Organix and FlexEDR Selective systems.

Industry Leading Performance

  • High selectivity monovalent ion exchange membranes (i.e. remove chlorides and leave in sulfates) that enable advanced separations previously impossible
  • High multivalent ion transference removes scaling ions for reduced fouling in downstream RO and concentration processes
  • Resilient in scaling and oily wastewaters, hydrocarbon tolerance C1–C10

  • Highly resistant to oxidizing agents (up to 1,000 ppm) including bleach

  • Stable over pH 0–12 and up to 60°C (140°F)

  • Smooth membrane surface minimizes fouling and scaling

  • Mechanically strong — ductile and tear resistant

Groundbreaking Selectivity

  • Effectively separate mono- and multi-valent ions with 98% monovalent ionic selectivity
  • Perform previously impossible chemical separations
  • 40% higher selectivity than conventional ion exchange membranes

Solution for Wide Applications

  • Selectively remove ions and dissolved salts
  • Desalt water with high organics 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

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

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.
