Membrane Filter Press
Membrane Filter Press
Membrane plate filter press operate by using flexible filter membranes in each chamber. These membranes expand under compressed air or hydraulic pressure, exerting a force on the filtrate and filtering the water. Membrane filter presses have a significant impact on the dryness of solids through the use of membrane technology in the filter plates.

These membranes expand under compressed air or hydraulic pressure, exerting a force on the filtrate and filtering the water. Membrane filter presses have a significant impact on the dryness of solids through the use of membrane technology in the filter plates. This process minimizes the residual moisture content in the filter cake compared to conventional filtration processes. This makes the membrane filter press a powerful and most widely used system.
Maximum dry matter content in the filter cake even if the filter chamber is partially full
Simple and economical filtration due to high degree of dewatering and short cycle times
Compact and robust design
Maximum versatility through expansion modules and automation options
High level of safety through the use of the latest safety technology
Reduced wear of the pump by abrasive media due to low feed pressure
The process involves several stages:
Filling: The feed slurry enters each chamber within the filter press.
Filtration: Initial filtration occurs through cloth-covered plates that separate solids from liquids.
Membrane Compression: After initial filtration, membranes inflate to exert uniform pressure, squeezing out additional moisture.
Cake Discharge: The solid ‘cake’ separates from the plates and discharges, while the purified liquid exits through the filtrate discharge valves.
Membrane filter presses work similarly to chamber and plate and frame filter presses that use polypropylene filter plates. However, the chambers in the filter plates have diaphragms that squeeze excess water out of the slurry. Thus, this type of filter press may be capable of removing large amounts of fluid. Thus, they may also be able to shorten the cycle time as long as the filter cake is compressible.
Membrane filter presses and squeezing plates are also considered when the solids content of the slurry is higher than average and/or variable in volume, and when the time savings of the squeezing process can be justified by higher equipment costs.
