Membrane Filter Presses are used for extra moisture reduction in the cake. It contains one membrane Plate which has the Thermo plaster elastomer and a companion plate made of solid Poly propylene. During the initial phase of the filtration, usually called filling cycle, the process is similar to the chamber filter press.
After reaching a predefined pressure-usually around 4-7 bar-depending on the liquid characteristics, Liquid feeding is stopped and the membranes slowly inflated, using oil as squeeze medium. The cake is hereby compressed and dewatered further. This process is continued up to 21 bar pressure. Then the squeeze medium is relieved and the cake discharged.
We are specially design for 30 bar membrane filter press. After getting the result as per our customer requirement.
Membrane filter plates are also designed just like as described above chamber plates. A flexible membrane is fixed to the support body. Materials for the membranes include Polypropylene, Synthetic Rubber (for example NBR, EPDM) or Thermoplastic Elastomer (TPE). The membrane is impermeable and serves to compress the cake within the chamber after the filtration process is complete. Liquid or gas (compressed-air) can be used as membrane inflation media. In order to guarantee maximum protection for the membrane filter press, we use special safety systems for the various membrane inflation media. Inflation pressures up to 24 bar, and in special cases even higher, are possible.
