AGC Engineering Co., Ltd.


What is an ion-exchange membrane?

We provide electrodialyzers, diffusion dialyzers, hydrogen ion selective membranes, monovalent ion selective membranes, high-durability membranes, and other ion-exchange membranes to meet particular applications.


The ionized substances in a liquid can be desalinated (salt concentration reduced) or condensed (salt concentration increased) using the ion exchange properties of Selemion to recover valuable materials and thereby clean and purify wastewater.

We supply not only membranes but a variety of process solutions, including diffusion dialyzers and other plant systems.
