Many years of experience

Products from Donau Chemie have been used for a long time in paper production in and around Austria.


In recent years, polyaluminium chlorides from the Donau PAC family have increasingly replaced "alum" (aluminium sulphate). The effect of aluminium is still indispensable for many tasks in papermaking. For example, our Donau PAC products are used in industrial water treatment, stock preparation, to improve retention and dewatering, sizing and waste water treatment.



In addition, other products from our portfolio such as Donau Bellamethan for the optimization of anaerobic wastewater treatment or the flocculants of the Donau Multifloc series are also used.

Flotation in Industrial Processes

Flotation is a key process for the efficient separation of solids from liquids. It is used in water and wastewater treatment as well as in numerous industrial processes.


With carefully tailored products, Donau Chemie supports reliable and cost-effective process operation.

Typical Applications & Solutions

  • Solid-liquid separation

    Efficient removal of the finest particles from liquids

  • Wastewater pretreatment

    Reducing the load on subsequent treatment stages

  • Process water treatment

    Improving water quality for industrial applications

  • Optimization of existing plants

    Increasing the efficiency of flotation processes
