MR Schwefelsäure en

Project background

In an anodising plant sulphuric acid is produced, which is contaminated with aluminium.

  MR Schwefelsäure Beitrag

Goal and challange

The objective is to remove the aluminium from the sulphuric acid and thus return the acid to the process.


Concept and realisation

Completion of a treatment plant that reliably brings the aluminium content of the sulphuric acid below the limit specified by the customer. A nanofiltration system resistant to sulphuric acid is used for this purpose.


Advantages for customer

  • Saving of disposal costs through reuse of the sulphuric acid
  • Controlled process through circulation of the acid
  • Reliable process with low maintenance
  • Low chemical requirement

Facts and figures

 Commissioning:    2019
 Plant capacitiy:  4 m³/h
 Feed medium:   sulfuric acid (approx. 20%)
