Membrane filter press is a high-efficiency solid-liquid separation equipment designed for deep sludge dewatering and lower filter cake moisture. After the primary pressure filtration process, the membrane plates perform secondary squeezing to further extract liquid from the filter cake.

Advantages:

Lower filter cake moisture
The membrane filter press adds a secondary squeezing process after pressure filtration. This helps extract more liquid from the filter cake and achieve lower cake moisture for suitable materials.
High-pressure membrane squeezing
With high-pressure squeezing, the membrane plates can further compress the filter cake, improving liquid discharge efficiency and making the equipment suitable for deep dewatering projects.
Shorter filtration cycle
For suitable sludge or slurry materials, membrane squeezing can help shorten the filtration cycle, improve processing efficiency, and increase overall production capacity.
Better sludge volume reduction
Lower cake moisture means reduced sludge volume and weight. This can help customers reduce transportation, storage, and disposal pressure in wastewater treatment and industrial sludge projects.
Flexible automation options
Manual, semi-automatic, and automatic operation modes are available. The equipment can be configured with automatic plate pulling, drip tray, cloth washing system, conveyor, hydraulic system, and PLC control according to project requirements.
Suitable for high-solid slurry and difficult dewatering materials
Membrane filter press is suitable for materials that require stronger dewatering performance after primary filtration.

Selection Notes:

Membrane filter presses incorporate additional components such as membrane plates and a pressing system, resulting in higher equipment procurement costs compared to conventional chamber filter presses.
Membrane plates are wear-prone components that may age or become damaged after prolonged operation, requiring regular inspection and replacement.
The membrane pressing process imposes strict requirements on parameters such as pressure and time, necessitating careful control of the operational workflow.
Membrane filter presses are still classified as batch filtration equipment; in large-scale continuous production scenarios, their processing efficiency is somewhat limited.

FAQ:

1. What is a membrane filter press?

A membrane filter press is a highly efficient solid-liquid separation device that incorporates elastic membrane plates into a chamber-type filter press. By subjecting the filter cake to secondary compression through membrane inflation, it further reduces the moisture content of the filter cake and improves dewatering efficiency.

2. What is the working principle of a membrane filter press?

A membrane filter press first performs solid-liquid separation using a feed pump to form a preliminary filter cake; air or water is then introduced into the membrane to cause it to expand and compress the filter cake, further expelling residual moisture to achieve deep dewatering.

3. What is the difference between a membrane filter press and a conventional chamber filter press?

The main difference lies in the dewatering method: Chamber filter press: Relies primarily on feed pressure for filtration; Membrane filter press: Adds a membrane pressing step to the filtration process, providing secondary dewatering of the filter cake. Therefore, membrane filter presses typically produce filter cakes with lower moisture content.

4. Are the operating costs of a membrane filter press high?

Compared to conventional filter presses, membrane filter presses incorporate a membrane pressing system, resulting in slightly higher equipment investment. However, because they provide better dewatering performance, they can reduce subsequent costs such as sludge transportation and disposal.
