Goal and challange

The aim is to remove the aluminium from the phosphoric acid and return the acid to the process. Prior to the realisation of the large-scale plants, preliminary tests were carried out within the scope of our 4 steps 2 separation to select the suitable process.


Concept and realisation

Realisation of a multi-stage treatment in acid-proof execution by which the phosphoric acid can be recovered for the process.


Advantage for customer

  • Saving of disposal costs through reuse of the phosphoric acid
  • Controlled process through circulation of the acid
  • Reliable method with low maintenance requirements
  • Low chemical requirements
