Electrodialysis hadn’t evolved, until REDstack redefined it

Our Technology

We design and manufacture the most advanced electrodialysis (ED) and bipolar electrodialysis (EDBM) stacks on the market, purpose-built to power the next generation of salt removal, resource recovery and carbon capture.

Our stacks are the core component of innovative electrochemical systems used in industries aiming to save water, recover valuable resources and reduce emissions.

How It Works

01 Electricity and smart ion-selective membranes

REDstack’s electromembrane technology uses electricity and smart ion-selective membranes to treat water and recover materials.

02 Efficient salt removal

ED stacks remove salts efficiently from low-TDS water in industrial water reuse projects.

03 Circular Recovery

EDBM stacks split water into acid and base, enabling circular recovery of valuable resources.

04 Modular & scalable

Both systems are modular, scalable and easy to integrate in a wide range of industrial processes.

What makes REDstack different?

Energy Efficient

Up to 3x more energy-efficient than conventional ED systems, powered by patented flow distributors and intelligent process control.

High-Purity Recovery

Zero liquid cross contamination between compartments, crucial for high-purity recovery and closed-loop chemical reuse.

100% Leak-Free

100% leak-free operation with minimal maintenance and extended membrane lifespan

Smart Technology

Smart self-optimization based on water chemistry for stable, long-term performance

Flexible & Tailored

Flexible membrane compatibility—tailored to your application for maximum efficiency.
