The filtration process using a mechanical filter is based on the filtration under pressure.

The basic working principle of a filter press is explained as follows: A mechanical separator consists of a series of rectangular plates stacked on an assembly, with each plate separated from the next by a gasket or an adhesive seal.

The plates have openings or recesses on both sides, which are designed to collect the dewatered solid or precipitate.

The liquid to be filtered is injected or pumped into the separation vessel and the plates are then pressed together to contaminate the water in the interstices between the plates.

Field pressure is usually applied hydraulic or pneumatic cylinders.

As the pressure increases, the liquid is forced through the precipitate surface and gets cleaned through the recesses on the plates.

Passing liquid is collected in a designated tank in a container or silencer.

At the same time, the solid particles stay on the recesses, forming a dewatered solid or solid layer.

Applied force is sustained for a specified period until the desired level of filtration or cake consistency is achieved.

Once the filtration is complete, the plates are gradually opened, and the dewatered solid is extracted from the filter medium.

Filtration process can be repeated with fresh load to yield another batch of isolated substance.

Selection of filter cloth used in the mechanical oil filter press machine and the arrangement of the indentations on the plates assume a vital function in predicting the quality of separation of the filtration process.

Solid-liquid separation device is widely used for tasks such as sludge dewatering, metal and chemical recovery, and purification of compounds.

In industrial applications, the specific extracted solid substance by the filter press determines its compatibility for different downstream processes.

Some of the common of filter presses include sewage treatment, food processing, and product manufacturing.

The filter press's specific blend of capacity, cost-effectiveness, and usability makes it an desirable equipment for numerous solid-liquid separation requirements.
