Diffusion Dialysis Membrane Layers

Diffusion Dialysis membrane layers are currently used for the recovery of acid and alkali solutions in many industries.

 

The anion exchange membrane (AEM) and cation exchange membrane (CEM) for diffusion dialysis are a optimal solution to recycle and recover acids and bases due to their high recovery efficiency and easy integration in complex systems.

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

  • Stainless Steel Passivation

  • Chemical Machining

  • Stainless Steel Pickling

  • Acid Etching

  • ​Metal Finishing

 

... and many more.
