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.
Ion exchange membrane
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.
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
- 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

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.
Scale is a crust that forms on membranes, heat transfer surfaces, and on the inside of pipes as salts precipitate out of solution. It blocks flow, disrupts heat transfer, and increases energy requirements for water treatment systems
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.
