Membrane Filter Press

embrane Filter Press is a filter press installed with a mix of membrane plates and chamber plates. When high pressure water or compressed air is injected between the membranes, the membranes will expand and push against the filter cake, and squeeze residue water out of it. Membrane filter press can increase filtration efficiency and reduce cake moisture. It is especially suitable for materials that is compressible (like organic sludge) or applications where minimum cake moisture is desired.

Our high pressure membrane filter press adopts world leading TPE membrane technology, so that ensures reliable performance stability and long life-span.  It is widely used in various industries. Cake from membrane filter press can be secondarily squeezed under pressure max 2.0 MPa by high pressure water or compressed air to realize the lowest cake residual moisture. In some wastewater treatment industries, the final cakes can be used for landfill or burning directly.The membrane filter press can realize fully automatic operation when installed with online automatic cloth washing system, electronic valves and meters.

Working principle of Membrane Filter Press:

1.      Feeding:  Slurry is pumped into the filter press. The solids are distributed evenly on the filter cloths during the feed (fill) cycle.

2.      Filtration: Solids begin to build on the filter cloth trapping the ensuing particles and building a filter cake. The filter cake acts as a depth filter for solid/liquid separation. Filtrate exits the plates through the corner ports into the manifold.

3.      Filtration completed: When the correct valves in the manifold are open, the filtrate exits the press through the filtrate outlet. As the filter press feed pump builds pressure, the solids build within the chambers until they are completely full of filter cake.

4.      Membrane Squeezing: Once the chambers are full, the fill cycle is over, high pressure water or compressed air will start fill in between membranes of filter plates, pushing the membrane toward the filter cakes, squeezing the filter cakes to remove any residue water.

5.      Presssure relief:  when squeezing is over, high pressure water(compressed air) is released from between the membranes.

6.      Cake discharge: after pressure relived, the filter press is ready to discharge cakes.
