A membrane filter is a device used in various industrial processes to process fluids, especially in chemical and waste treatment applications. The equipment consists of a array of chambers that house parallel filter plates, together with a membrane filter, this configuration enables it to effectively separate solvents from solids.

Mastering the operation of a membrane filter press is essential in identifying the correct type of press for any given industrial application. Here's a detailed overview:-

The membrane filter press typically consists of a sequence of parallel plates with a flat gap between each. A elastic membrane is stretched across the superior and inferior of these plates, and on interchanging plates, a seal is placed to create a seal between the filters.

In use, the areas between the plates are fed with a liquids mixture containing the slurry. As the feed enters the area, high pressure is applied by the filter press machine for oil press's pneumatic system, pushing the fluid through the membrane filter. The matter that cannot pass through the membrane filter remain within the chamber.

As the chamber becomes saturated with the retained solids, water is removed using a measured drainage system, normally after shut-off of the area plates, by opening a drainage valve connected to a wastewater treatment or to a wastewater treatment unit.

In the meantime, the layers that prevent the passage of particles to the underpressure plate on opposite sides, give up water, causing the mixture to become increased concentrated. Excess water is usually drained before the filter press shuts down, after all of the spaces have been filled and filtered.
