Plate Size
Once the cubic foot capacity of a filter press has been determined the next step is, the proper selection of the size of the filter plates, frame, components and any accessories. This will allow you to see exactly where the cu. ft. capacity fits in relation to the volume of each size press. For example a 5 cu. ft. can be sized as a 470 mm, a 630 mm and also an 800 mm. The size selected is determined by the amount of expandability desired. After the plate size is selected, there are many options from which to choose. The following information is a summary of what needs to be considered in order to make the proper selection, Please read each section in turn and note your requirements.
BRIGHT contains other products and information you need, so please check it out.
Plate Construction
Select the type of filter plate material. The standard material is an industrial grade polypropylene. An optional FDA approved food grade polypropylene material, or a high temperature glass filled polypropylene material are also available. Special materials are also available such as Carbon Steel , Stainless steel and Kynar.
Plate Style
The standard is a 100 psi recessed gasketed plate with EPDM seals. Viton seals are available as an option. Also available are non-gasketed plates with quick removal latex edged cloths, where the cloth acts as the gasket. The Non gasketed plates allow for easier change out of the filter cloth, are lower in cost, but are not completely liquid tight during the processing stage. Special membrane squeeze plates have the ability to expand after the chambers are full to “squeeze” additional process liquid out of the filter cake. A “mixed stack” of plates will be provided where every other plate will be a special membrane squeeze plate
Optional Backing Plate
If a shorter cycle is desired, when running low volume applications for example, the capacity of the filter press can be temporarily reduced. This is done by moving the follower (tail) plate forward in the plate stack. The backing or “blank plate” is then placed behind the follower plate acting as extra support. The follower plate will not flex or break when used in this manner.
Plate and Press Pressure Rating
The 100 psi design is standard for most dewatering applications and will produce a cake with approximately 30-35% solids. A 225 psi design can be used to provide an increased yield per cycle and depending on the application can increase the solids in the cake to 50% or more.
Cake Thickness
The 32 mm cake thickness is standard. Options include 25, 38 and 50 mm cake thickness. 25 mm would be used for high viscosity (slimy) materials and 50 mm would be used for easily filtered material.
Cloth Type
ErtelAlsop can provide filter cloths in many different materials, weaves, thread styles, and air permeability values resulting in a wide array of performance characteristics. If possible ErtelAlsop would like to receive samples of the process liquid to conduct filterability tests for cloth selection. If testing is not possible then we will furnish our standard polypropylene filter cloth, a monofilament x multifilament, Sateen weave with a CFM<1.0.
Frame Design
All ErtelAlsop frame configurations are sidebar design. Frames can be designed in Carbon Steel or Stainless Steel.
Volume of Plates/Expansion Spacer
All filter presses are available with optional removable expansion spacer. On presses ordered with a spacer, the first number denotes current plate capacity. The second number in the nomenclature is the maximum capacity the frame will allow.
Discharge/Air Blow-down Piping
The discharge/air blow-down piping is available in either manual or in automatic operation. An optional core blow-down is available to purge the center feed line of residual fluid. Available materials of construction are schedule 80 CPVC, or schedule 40 Stainless Steel.
Feed Style
The feed style can vary for special applications such as pharmaceuticals and some type of food processing. Center feed is standard, however a choice of any corner feed is available.
Automation versus Manual Operation
Manual or semi automatic operation requires input from an operator to start and operation of the filter press, including opening and closing, blow down, plate shifting etc. Fully automated presses require initial start up of operation and then close fill, blow-down, plate shift, discharge and cloth wash is automated. Restarting the press cycle still requires operator input.

What is a filter press and how does it work?
A filter press is a mechanical device used to separate solids from liquids in various industries. It works by forcing a slurry into a series of filter plates, where the liquid passes through the filter cloth, leaving the solid material behind. This process creates a cake of solids that can be easily removed, making it efficient for dewatering and filtration.
What industries commonly use filter presses?
Filter presses are widely used in industries such as mining, wastewater treatment, food and beverage, pharmaceuticals, and chemical processing. They are essential for processes that require solid-liquid separation, helping to improve product quality and reduce waste.
How do I choose the right filter press for my needs?
To choose the right filter press, consider factors like the type of material you need to filter, the desired cake thickness, and the volume of slurry. Additionally, evaluate the available space, budget, and maintenance requirements. Consulting with a manufacturer can help you find the best fit for your specific application.
What maintenance is required for a filter press?
Regular maintenance for a filter press includes cleaning the filter plates and cloths, checking for wear and tear, and ensuring proper alignment of the hydraulic system. It’s also important to inspect seals and gaskets for leaks. Following the manufacturer’s guidelines will help prolong the lifespan of your equipment.
How long does it take to manufacture a filter press?
The manufacturing time for a filter press can vary based on the complexity and specifications of the unit. Generally, it can take anywhere from a few weeks to several months. Factors such as customization, material availability, and production capacity of the manufacturer can influence the timeline.
