Membrane Filter Press

High Pressure Rubber Membrane Chamber Recess Plate

Because of its simplicity and flexibility, the chamber filter press has been widely applied in clarification and dewatering applications. Membrane filter press technology is gaining increased acceptance because it reduces subsequent processing or disposal costs for filter cake.

High Pressure Rubber Membrane Chamber Recess Plate

In many applications the membrane filter press significantly reduces residual moisture content, making this technology attractive for new plants and for upgrading existing facilities.

High Pressure PP Combination Chamber Plate

In both cases the careful selection of plate and membrane materials is essential to the successful performance of the process. Membrane filter press plates have a chamber below the drainage surface that can be inflated.

Automatic Membrane Filter Press With Multi Stage Plate Shifting

The common method used is water pressure, which is generated by pumping into the squeeze cavity to inflate the face of the plate against the filter cake. Membrane plates are used to reduce the cake moisture content & shorten the filtration cycle time.

Air Manifold For Membrane Squeezing

Mix pack membrane are the most common configuration (one recessed plate then one membrane plate alternate in the press plate pack). Membrane plates usually operate at a feed pressure of up to 7 bar and squeeze pressure up to 15 bar.

Dual Pump Unloader Type Hydraulic Motorized Power Pack

Special plates can be designed for higher feed & squeeze pressure. Replaceable membranes can easily changeable. Epdm thermoplastic and other compounds are used for specific conditions.

Core Blowing Pipes & Auto Valves On Hydraulic Closing Side

Plate filling problems are minimized and use of a rubber membrane enables empty-chamber operation without damaging the plate, resulting a considerable reduction in incidents of plate failure.

Automatic Multi Stage Plate

Even if the chamber is not completely filled, the filter cake is squeezed by the inflating filter lever and therefore perfectly dewatered. During the initial phase of the filtration cycle, so-called fill and filtration the process is similar to the chamber filter press.

Specially Designed Lever & Links For Automatic Plate Shifting

After reaching a predefined pressure, usually around 3 - 7 bar, depending on the sludge characteristics, sludge feeding is stopped & the rubber membranes inflated, using either water or air as squeeze medium.
