Filter Press Plates

Evoqua offers the largest selection of filter plates for filter presses, for every application in your dewatering process.

Evoqua offers the largest selection of filter press plates available for all dewatering applications.

Separating solids from liquid is a process utilized in a myriad industrial processes from metal finishing, battery recycling, paint, municipal power and many others. Cleaning your slurry effectively is dependent on combining the correctly-sized filter press, just the right filter cloth and the right filter plates.

Filter press plates must be strong and oftentimes, corrosion-resistant. Filter plates must also be able to withstand extremely high pressures and high volumes (throughput) of slurry.

Filter presses and their corresponding filter plates are found in many industrial separation processes, from automotive, food and beverage, municipal waste, mining and many others.

Evoqua provides filter press plates for all slurry and sludge dewatering applications. They are designed to withstand the pressures of your specific application whether it's metal finishing in the automotive industry, or tailings in the mining industry.

Expert staff in our state-of-the-art laboratory are essential in specifying the size of your filter press which also determines the size and type of filter press plate that goes with that press for your specific application. For example filter plates for a mining application are different from filter plates for a battery recycling process.

Corrosion resistant polypropylene plates are available in recessed chamber and diaphragm squeeze (membrane) designs. Diaphragm squeeze plates are also available with replaceable diaphragms made of PP, PVDF, Nylon or EPDM.

 Which filter press plate is right for you?

Filter packs can be configured as full recessed packs for fixed volume filtration, full diaphragm squeeze packs for variable volume filtration or mixed packs where diaphragm squeeze plates alternate with recessed chamber plates for a cost-effective alternative to an all-diaphragm squeeze plate design.

Filter cloths are also available in a wide variety of weave patterns, weights, materials and porosities and are specifically selected to best fit your application and desired results. Like the J-Press® filter press, the filter plates can be designed to withstand specified operating pressures. 

  • Diaphragm (or membrane) plates feature flexible drainage surfaces that expand to exert additional pressure on the filter cake, further reducing moisture.
  • Plate and frame filter packs are available for polishing applications.  Gasketed plates form a tight seal due to O-rings around the recessed chamber and filtrate discharge eyes, allowing for a virtually leak free operation. 
  • Filter cloths are available for all gasketed and non-gasketed plates material and weave pattern are selected for your specific performance requirements.
