Electrodialysis Test Systems: From Membrane Screening to Pilot Design

At a glance. Electrodialysis moves ions through ion-exchange membranes under an electric field. The Tech Inc. Electrodialysis Test System runs a laboratory stack with diluate, concentrate and electrode-rinse loops, and logs current, voltage, conductivity and pH.

What you can measure

• Current efficiency and energy per kg of salt removed.

• Limiting current density for each membrane pair.

• Acid and base production with bipolar membranes.

• Scaling and fouling under polarity reversal (EDR).

Applications

Brackish water desalination, brine concentration for zero liquid discharge, lithium and resource recovery, and demineralisation in food and pharma.

Frequently asked questions

Can we use our own membranes? Yes; the stack opens for membrane and spacer changes.

Does it scale? Results define cell pairs, current density and area for a pilot stack.
