Membrane Filter Press

The membrane Filter Press utilizes a modular design similar to that of the chamber filter press. The robust steel filter press frame consists of the following main components: feed frame with filtrate outlet (head unit), hydraulic frame with locking cylinders (pressure unit), crossbeam and side rails on which the individual membrane filter plates (including filter cloth) are mounted. The plate set consists of homogeneous membrane plates (optionally also mixed chamber membrane filter plates) with cut-outs of 15-50 mm to accommodate the puncture-proof filter cake.

Membrane filter presses have a significant impact on the dryness of the solids through the use of membrane technology in the filter plate. This process minimizes the residual moisture value in the filter cake compared to conventional filtration processes. Membrane filter presses have proven their superiority in a variety of applications such as mining, chemical or pharmaceutical.

Filtration Principle

Membrane filter presses are fed in the same way as chamber filter presses, but the filling level of the chamber can be controlled manually. The increasing feed pressure ensures pre-compression and dewatering of the filter cake in the chamber. As soon as the feed pressure reaches a predetermined value (approx. 6-8 bar), the filter cake is squeezed again. A flexible membrane (e.g. filled with compressed air or water) presses the cake solids against the entire surface of the chamber. This compresses and discharges free water onto the filter cloth.

Advantages

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 due to the latest safety technology
