Filter presses have been known for over a century. Initially, they were known as ‘błotniarki’ – name derived from the Polish word ‘błoto’ meaning mud. Firstly, they were equipped with wooden, and later on with cast iron plates and frames, closed with a screw downholder. The hardship in handling and low filtration pressure, led to the end of their usage. At the beginning of the 80’s, chamber filter presses were updated and equipped with light plates made of polypropylene – material highly resistant to chemical agents and mechanical shocks. The downholder and sliding apart plates have been modified and fully automated. Currently, filter presses are characterised by a large filtration surface in a compact housing and warrant efficient sludge dewatering, which is widely recognised as difficult to dewater. The equipment depends on the needs and requirements of our Customers.

The standard realisation of a filter press includes:

  • Press structural construction, together with heads and hydraulic cylinder
  • Set of polypropylene filtration plates
  • Set of filter clothes
  • Hydraulic power pack
  • Press electricity supply and control system
  • Mechanical plates slide apart system 

Additional equipment may include:

  • Sludge pomp system – membrane, displacement, screw, with automatic performance adjustment as a feature relating to pressure
  • Lower flip drain hatches with electro-pneumatic drive
  • After-filtration sludge collection – mobile container, tape or screw conveyor
  • Automatic and half-automatic cloth washers
  • Sludge preparation system – coagulant and polyelectrolyte dosing base
  • Control cabinet with the whole filtration system visualisation
  • Elevating constructions for press foundations
  • Disinfection line

The filtration results depend on many factors. Among them:

  • Kind of sludge feed on the press (crystalline, amorphous, fibrous etc.)
  • Used filtration aids
  • Surface and capacity of filtration chambers
  • Sludge feed pressure
