Whatever the case, the process engineering knowledge for the overall concept remains within our company. This means that we are able to determine the most practical procedure for every application and to combine individual products into the optimum solution.

We provide solutions for all aspects of water management in the paper and pulp industry:

We have the answer to every specific issue of raw materials, production and location regarding our customers’ process water and waste water treatment needs whatever they may be.

Process water treatment:



  • Custom water treatment for all applications in the paper and pulp industry – even for water from problematic sources
  • Selection of processes with optimised operating costs
  • Partial-stream treatment to achieve and maintain top quality

Technical solutions for process water treatment:



  • FLOCOPAC or FLOCOMAT high-capacity contact sludge clarifiers for river water treatment and decarbonisation
  • Membrane and ion exchange processes for further process water treatment, steam generation or power station operation

Waste water treatment and recycling plants:



  • Custom waste water treatment for all applications in the paper and pulp industry
  • Selection of processes with optimised operating costs
  • Full and partial-stream treatment to achieve the required discharge or recycling qualities.
