Fully automatic filter presses



The AF filter presses from AQUACHEM are a further development of conventional chamber filter presses, which have been tried and tested in the industry for over a century. However, due to the degree of automation required and the increase in efficiency necessary nowadays, the technology we have had up until now is often no longer up to date. The design of the AF filter presses is based on the optimum interplay of the ?? individual assemblies of the filter press to ensure reliable, efficient and permanent operation without personnel being present. The automated flexibility of the product enables autonomous adjustment to changing conditions, such as concentration or even specific filter properties. We guarantee these properties and also availability. This is only possible because AQUACHEM and the AF-series possess the knowledge, an intelligent control system and the technology for maximum flexibility. Yes, this is a product with unique selling points – test it out yourself.


Product properties

  • Fully automatic operating mode without supervision
  • Compact and robust design
  • Three operating modes, optionally optimised for
    • Throughput in l/m²/h
    • Result of the filter cake (dry solids content)
    • Energy consumption / m³ and wear
  • Up to 10 times the throughput in l/m²/h possible compared to conventional chamber filter presses
  • Maximum operational reliability
  • Maximum availability
  • Low-maintenance and easy to maintain
  • Comparatively few sensors and moving parts as per the principle "as few as possible, as many as necessary"
  • Five sizes: 470, 630, 800, 1,000 and 1,200 mm plate format
  • Membrane filter elements
  • HMI control system with touchscreen
  • Logging of all process data on an SD card
  • Prepared for all possible feeding pumps
  • Reliable
  • Dependable
  • Signal exchange with higher-level control systems


  • Comparatively low life-cycle costs
  • Comparable investment to conventional presses because the AF filter press requires less filtration surface for the same output
  • Lower disposal costs possible due to higher dry solids content in the filter 


The design is based on the sediment load and the hydraulic quantity. The filter properties of the material are vital to the design. If they are not yet known, we can determine them in our laboratory.

The technical and economical suitability and the potential output in l/m²/h can be determined on site with our testing filter presses AF 470 Mini and AF 800. These machines are installed conveniently in a container and can be set up very easily at the customer's location.
