The Tech Inc. Electrodialysis (ED / EDR / BPMED) Test System tests ion-exchange membranes and stacks for electrodialysis (ED), electrodialysis reversal (EDR) and bipolar membrane electrodialysis (BPMED). Diluate, concentrate and electrode-rinse loops are pumped through a laboratory stack while a DC supply controls current or voltage and the system logs conductivity, pH and temperature.

Main components

Laboratory stack with 5 to 20 cell pairs and replaceable membranes and spacers
Three circulation loops: diluate, concentrate and electrode rinse
Programmable DC power supply with polarity reversal for EDR
Conductivity, pH, temperature and pressure on each loop
PLC with touch screen and data logging

Applications: Desalination of brackish water, brine concentration, acid and base recovery, lithium and resource recovery, and food and pharma demineralisation.

Electrodialysis (ED / EDR / BPMED) Test System

ED system – standard electrodialysis.

EDR system – automatic polarity reversal.

BPMED system – three-compartment stack for acid and base production.

Pilot stack – larger cell area for scale-up.
Active area: about 64 to 400 cm² per membrane

Cell pairs: 5 to 20

DC supply: up to 30 V and 10 A, programmable

Loops: three, with conductivity and pH

Materials: PVC, PP or PVDF wetted parts
Three processes in one – ED, EDR and BPMED with the same skid.

Full data – current efficiency and energy use calculated.

Easy rebuilds – stack opens for membrane changes.
