These are advance version of Recessed Chamber Closed configuration plates, where Filter Cloth is caulked in the caulking groove around the recess plate. Major benefits of this design are Zero leak Recess Type Filter Plate because O Ring seats around the sealing edge and filtrate hole secure tight seal when the plate pack is closed. Cloth caulking groove provide easy installation and least maintenance of the filter cloth. CGR plates are recommended and necessary for leak proof conditions like toxic substance, acidic solutions etc. O Ring are available in the different elastomers like EPDM, Neoprene, viton etc. These plates are available with center, top, bottom and corner feeding with adaptable diameter and designed at 8 and 16 bar operating pressure.

The working room of the membrane filter press consists of chambers, limited by two adjacent plates with recesses in the central part. Unlike the chamber plates, the drainage draining the filtrate is located on movable membranes serving for pressing and wringing of the filtrated cake. Water or air under pressure is used to compress the membranes. Once the filter press is filled with the suspension, this medium is fed to the room under the membranes and its subsequent lifting compresses the cake and pushes out the residual liquid. The liquid passes through the cloth and is discharged out of the filter press. The thickness of the filtration chamber is usually 30 50 mm before compressing, by compressing the membrane it is reduced most often by 20 40%.The suspension is fed via a central or corner inlet passing through the whole set of plates. The filtrate is drained by drainage on the membrane surface (under clothes) and then by channels drilled inside the plates out of the filter press. Filtrating (filling) pressure before the start of the membrane compression is usually 8 bars, it rises up to 15 bars during compressing (structurally, we manufacture filter presses to a maximum pressure of 30 bars).The filter presses are equipped with a security system, which will not enable opening of the filter presses if the system of membrane compression was not previously decompressed. This prevents from damaging to the membranes by accidental opening of the filter press. The filtration plates including membranes are standard made of polypropylene, another material can be chosen.
