IONPAQ™ Diffusiondialysis

Diffusiondialysis-membranes are available both for acid-dialysis or lye-dialysis.

The membranes for aciddialysis are selectively permeable for anions and H+-ions and not for other cations. The transport is facilitated by diffusion with the concentration-gradient of the acid as the driving force.

In a similar way the lye-dialysis membranes are permeable for cations and OH-. The process itself is quite simple.

Typical applications of IONPAQ™ Diffusiondialysis

  • Hydrochloric acid recovery or production
  • Sulphuric acid recovery or production
  • Nitric acid recovery or production
  • Fluoric acid recovery or production
  • Caustic recovery or production
