Saltworks’ FlexEDR electrodialysis reversal technology has been selected by a heavy industry client located in Chile to recycle their wastewater. The FlexEDR system, provided in partnership with Chile’s VIGAflow, will use Saltworks’ proprietary IonFlux ion exchange membranes.
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 MembranesOur 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.
- 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
Solutions in Broad 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

- 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
Electrodialysis (ED) technology is the second most widely used membrane desalination technology and has been developed since the 1960s for a wide range of industrial applications.
As regulations on FGD wastewater tighten, additional treatment is required. Often, this is chemically intense, and high cost. The best means to lower treatment costs is to reduce the volume of wastewater generated, usually by increasing internal recycle.
This pilot demonstrated the economic and process advantages of targeting concentrated streams for salt removal. Today, Saltworks Technologies launches its FlexEDR product line – the next generation electrodialysis reversal technology for challenging waters.
