Diffusion Dialysis Anion Exchange Membranes Working Principle
​Acid recovery via Diffusion Dialysis utilizes an Anion Exchange Membrane (AEM) as a semi-permeable barrier placed between a flowing water stream and a flowing acid stream which contains dissolved metals. The anion exchange membrane has a fixed positive charge located on its surface. These positively charged locations attract the negatively charged anions in solutions that come in close contact with the anion exchange membrane surface.
Diffusion Dialysis Anion Exchange Membranes main applications for acid recovery:
​
-
Iron & Steel Pickling
