Solutions for the safe separation of substances

Continuous or batch operation

Separation solutions from BHS-Sonthofen are the first choice in the chemical industry. Whether in continuous production or in batch operation, our filter systems deliver high quality and impressive throughput rates. The BHS experts put their decades of experience to work for you, advising you on process planning for a vast range of process steps in the production of chemical products. Together with you, we develop a customized solid-liquid separation solution that best meets your application needs.

Highly efficient processing of the solid

In addition to the rotary pressure filter, the indexing belt filter (BF) is also used in the processing of a wide range of chemical products – especially for applications involving abrasive solids. Both filter systems are highly efficient due to multi-stage cake processing.

Together with your input, we design the separation solution that best suits your needs. The solution we will develop guarantees maximum yield, high product quality and minimizes the total cost of ownership.

Benefits at a glance:

  • Self-regulating filter systems
  • High system availability
  • Safe operation
  • Multi-stage cake treatment
  • High yield and product quality
  • Low total operating costs


Safe production of agrochemicals


Safe production of agrochemicals

For manufacturers of plant protection products such as pesticides, fungicides and herbicides or fertilizers the most suitable closed system for the production of agrochemicals is the rotary pressure filter (RPF). The continuously and fully automatic high-performance filter offers maximum safety and requires no manual intervention other than maintenance. The machine facilitates gas-tight cake treatment in several discrete process steps.


Safe processing of bio-based chemicals

Safe processing of bio-based chemicals

In the processing of chemicals based on renewable raw materials, the filter systems from BHS-Sonthofen ensure high product quality and yield as well as efficiency in the treatment of the solids. Examples include cellulose derivatives or bio-based polyamides.

Our filters in use

Rotary pressure filter (RPF)

A single rotation of the drum entails a number of different process steps, demonstrating the many facets of filtration.

Indexing belt filter (BF)

This type of vacuum filter is particularly gentle on sediments.

Tests give certainty

Which technology is the right one for your process? Don’t leave anything to chance. Based on your specifications, we carry out testing and identify the best solution for you in our filtration laboratory.
