Frequently Asked Questions

Get answers to common inquiries about our products and services.

What is a bipolar membrane?

A bipolar membrane (BPM) is a specialized ion exchange membrane composed of a cation-exchange layer and an anion-exchange layer. When a reverse voltage is applied, it splits water into H⁺ and OH⁻ ions, enabling acid and base production from salts.

Can I use your membranes in vanadium flow batteries?

Yes, we offer specialized ion exchange membranes optimized for vanadium redox flow batteries, ensuring high ion selectivity, low crossover, and long cycle life.

Do you provide custom membrane stack configurations?

Absolutely. We design and manufacture custom membrane stacks tailored to your voltage, flow rate, and space requirements.

How do I maintain an electrodialyzer system?

Regular cleaning with mild acid or base, periodic inspection of gaskets, and monitoring of pressure drops are recommended. We provide detailed operation manuals and technical support.
