Membrane Filter Press Definition

A membrane filter press is a filter press that uses a membrane plate along with an ordinary filter plate. It uses more pressure to separate the solids from the liquids. This makes the process more efficient and effective. The membrane filter chamber is made up of membrane filter plates and chamber filter plates. The feeding pump puts the sludge into the chamber. The filter cloth separates the solids and filtrate. When the solids form the filter cake, blow air into the membrane to dry the filter cake more. Diaphragm filter presses are great at reducing moisture content and improving the filtration process.

The membrane filter press is specially designed for thick, sticky materials and requires a higher level of moisture.

The membrane filter press is based on a new and improved way of filtering water using special plates. The plates are connected to a flexible membrane, usually made of high-quality polypropylene (PP), that can be inflated at the end of the filtration cycle. The membrane expansion puts more pressure on the filter cake, which makes it dry out more.

Diaphragm Filter Press Composition

Membrane Plates: These plates are made of polypropylene (PP), a type of plastic. They have a special layer of rubber inside that makes them flexible. They can be filled with air or water after the initial filtration phase.
Ordinary plates: Put them next to membrane plates to make filter chambers.
Filter Cloths: These are placed between each plate. They act as a filter to separate solids from liquids during the filtration process.
Other elements are the same as the common filter press. Control Panel (HMI), Hydraulic Cylinder, Hydraulic Station, Beam, and Drip Tray.

How to Reduce Filter Cake Moisture with Membrane Filter Press

The diaphragm filter press has two plates: a diaphragm plate and a standard plate. The plates are arranged in alternating layers.

For the first cycle of filtration, sludge or slurry is pumped into the chamber. The solids collect on the filter cloth, forming a filter cake. Inflation of the membrane: After the first cycle of filtering is done, the membranes in the filter plates will be filled with air or high-pressure water. This expansion puts more pressure on the filter cake, compacting it and squeezing out any remaining moisture. Squeezing out water and reducing moisture. Applying this pressure increases the dry solids concentration of the filter cake, effectively reducing its moisture content. This process makes the filter cake drier.

Membrane Filter Press Working Principle

Membrane filter press plates have a chamber below the drainage surface that can be inflated. The most common method uses water pressure. Water is pumped into the squeeze cavity to inflate the plate against the filter cake. Membrane plates are used to reduce the moisture content of the cake and shorten the filtration cycle time.

At the start of the filtration cycle, the process is similar to the Chamber Filter Press. This is called the “fill and filtration” phase. When the pressure reaches a predefined level (usually around 5–7 bar, depending on the sludge characteristics), sludge feeding is stopped. Then, rubber membranes are inflated using water or air as a squeeze medium. The cake is compressed and dewatered some more. Then, the pressure on the medium is released and the cake is removed.

For those with a filter cake washing system, the filter cake will be cleaned before unloading. This design can pass clean water through the washing port of the filter plate to clean the filter cake and remove any remaining impurities. You can also use compressed air to dry the filter cake through the washing port. This is especially helpful in industries like pharmaceuticals and food production, where filter cake purity is crucial. The washing process of membrane filter presses can be changed to meet specific needs to get the best results.
