What a plate filter presses is and how it works?
A plate filter presses is a device used to separate solids from liquids through a filtration process. It is commonly employed in various industrial sectors and production processes to separate solid particles from liquid suspensions.
The filter presses consists of a series of concave plates, a support frame, a network of pipes and channels for mud and water transport, and a range of optional features to optimize its operation.
Thanks to the pressure exerted by a feed pump, the filter press can squeeze the liquid through the filter cloths covering the plates, retaining solid particles inside the chambers, and discharging this dried sludge at the end of the process.
The filtration process in a filter press typically involves the following steps:
- Feeding the material containing solids and liquids into the filter press.
- Applying pressure to force the liquid through the filter cloths, thus separating solid particles from the liquid.
- Collecting clean water through an external channel.
- Discharging and collecting the dried sludge in cakes.
Filter presses are used in various sectors, such as wastewater treatment, chemical production, the food and pharmaceutical industries, and many other contexts where it is necessary to separate solids from liquids.There are different types of filter presses, including plate and frame filter presses, chamber filter presses, and membrane filter presses, each with its own characteristics.

How does a filter presses work?
The operation of a filter press is based on a series of phases, all aimed at achieving a perfect separation of solids and liquids. Here is a general overview of how a filter press operates:
- Mud Feeding: the material to be filtered, usually a sludge, is introduced into the filter press. This slurry contains liquid and solid components.
- Chamber Filling: the filter press is composed of a series of vertical concave plates covered with filter cloths. These adjacent plates, when pressed together, create chambers or gaps between them where the sludge is directed. The sludge fills these chambers, and as the spaces between the plates fill up, the liquid begins to flow through the filter cloths, while solid particles are retained.
- Filtration Process: once the chambers are filled, the constant pressure applied to the sludge allows it to self-filter. This pressure can be achieved using hydraulic systems, manual screws, or other methods depending on the type of filter press, but it typically occurs through centrifugal or pneumatic pumps.
- Filtrate Collection: the liquid that passes through the cloths, known as filtrate, is collected and typically directed into a separate container for further processing or disposal.
- Formation of Solid Cake: the solid particles retained by the filter press cloths form a cake-like layer inside the chambers between the plates.
- Cake Release: once the filtration process is complete, the filter press is opened, and the dry cake is discharged from the plates. This material can then be disposed of or further processed, depending on the application.
