The LEPUU plate filter press provides batch solid–liquid separation for mineral concentrates, tailings, sand washing sludge, and compatible industrial slurries. It separates slurry into filter cake and filtrate, supporting solids handling and process water recovery.
Filter cloth, feed pumps, and automation options are selected to suit your material and operating requirements.
A plate filter press uses a series of cloth-lined filter chambers to separate solids from liquids. A feed pump delivers slurry into the closed chambers. Liquid passes through the filter cloth and flows out through drainage channels, while solids remain inside and gradually form a filter cake.
The press operates in batches. After filtration, feeding stops, pressure is safely released, and the plates open for cake discharge. The filter cloth and sealing surfaces are then checked before the next cycle.
Selecting a filter press requires more than choosing a filter area. Feed solids concentration, particle size, filtration resistance, chamber volume, and cycle time all influence processing capacity.
Remove water from mineral concentrate before downstream storage, transport, or processing. Filter cloth and operating conditions should be selected according to the concentrate’s filtration characteristics.
Separate tailings slurry into filter cake and filtrate as part of a tailings management system. Cake handling and water recovery arrangements depend on the project requirements.
Dewater fine solids collected from sand washing and clarification processes. The filter press can be integrated with a thickener, slurry tank, and feed pump.
Separate solids from compatible industrial process slurries and wastewater sludge. Material compatibility and filtration performance should be evaluated before equipment selection.
Slurry Collection → Thickening or Conditioning → Feed Pumping → Pressure Filtration → Cake Discharge and Filtrate Collection
| Process Stage | Purpose |
|---|---|
| Slurry collection | Collect slurry from the upstream process |
| Thickening or conditioning | Prepare the feed where required by the application |
| Feed pumping | Deliver slurry into the filter chambers |
| Pressure filtration | Retain solids and separate liquid through the filter cloth |
| Cake handling | Collect or transfer the dewatered solids |
| Filtrate collection | Direct separated liquid to treatment or reuse |
A thickener can increase feed solids concentration before filtration. A buffer tank can help coordinate the incoming slurry supply with the filter press’s batch cycle.
After filtration, cake is collected below the press or transferred by a suitable conveyor. Filtrate flows to a collection tank for further treatment or reuse, depending on its quality.
The closing mechanism brings the filter plates together and maintains the clamping force needed to keep the chambers sealed during filtration.
The feed pump delivers slurry into the closed chambers. Feed pressure drives liquid through the filter cloth while suspended solids remain inside.
Solids accumulate in the chambers and form a filter cake. As the cake becomes thicker, filtration resistance increases. Filtration ends according to the operating criteria established for the material and equipment.
Feeding stops and pressure is safely released before the plates open. The cake is discharged using the arrangement supplied with the press. Plate shifting may be manual or automatic, depending on the configuration.
The filter cloth and plate sealing surfaces are inspected. Remaining solids are removed, and cleaning is carried out as required before the press closes again.
Optional membrane squeezing: A secondary squeezing stage is available only on equipment fitted with membrane plates and a compatible squeeze system. Availability must be confirmed for the selected model.
Pressure filtration produces two streams that can be handled separately: retained solids and collected liquid.
Filtrate can be directed to a treatment or reuse circuit according to its quality and the plant’s water requirements.
Dewatered cake can simplify solids collection, transfer, and storage compared with handling the original slurry. Final cake moisture and consistency depend on the material and operating conditions.
Plate size, chamber volume, filter cloth, and feed pump duty are evaluated together to suit the required solids load and filtration cycle.
Automatic plate shifting, cloth washing, and other control functions may be available for specified configurations. Included features should be confirmed in the equipment proposal.

A filter press installation must coordinate slurry feeding, filtrate collection, cake discharge, and maintenance access.
Depending on the application, the press can be connected to upstream thickening equipment and downstream cake collection or conveying equipment. The installation layout should allow sufficient space for plate opening and filter cloth replacement.
The following parameters should be confirmed for the selected model.
| Parameter | Unit / Description |
|---|---|
| Model | Selected model designation |
| Filter area | m² |
| Filter plate dimensions | Width × height, mm |
| Cake thickness | mm |
| Chamber volume | L |
| Number of filter plates | pcs |
| Rated filtration pressure | MPa |
| Overall dimensions | Length × width × height, mm |
| Equipment weight | kg |
| Automation configuration | Included control and handling functions |
Processing capacity and final cake moisture depend on the feed material and the complete filtration cycle. Installation dimensions and equipment weight should be checked against the final approved drawing.
Provide sufficient space for plate opening, cake discharge, filter cloth maintenance, and access to the closing assembly.
The feed pump, piping, filtrate collection system, and cake handling equipment should be coordinated with the filter press configuration.
Routine operation includes:
Operating procedures and maintenance intervals should follow the instructions supplied with the equipment.

Service scope and delivery arrangements are confirmed according to the supplied equipment and project agreement.
What information is needed to select a plate filter press?
Provide the material type, slurry flow rate, solids concentration, daily operating hours, and required cake condition. Particle size, temperature, pH, and material compatibility requirements also help determine a suitable configuration.
Can filter area be converted directly into processing capacity?
No. Different slurries require different filtration times on the same filter area. Processing capacity depends on the dry solids load, chamber volume, filtration behavior, and total cycle time, including cake discharge and cleaning.
Does every plate filter press include membrane squeezing?
No. Membrane squeezing requires membrane plates and a compatible squeeze system. Confirm whether this function is included in the proposed equipment configuration.
Can the filtrate be reused directly?
This depends on the filtrate quality and the plant’s process water requirements. Further clarification or treatment may be needed before reuse.
Can a plate filter press operate automatically?
The automation level depends on the selected configuration. Automatic plate shifting, cloth washing, and other control functions should be confirmed in the equipment proposal.
What affects the final filter cake moisture?
Material properties, particle size, feed solids concentration, filtration pressure, cycle duration, and equipment configuration all affect cake moisture. Testing with representative slurry helps evaluate the achievable result.
