    industrial filter press


    fully automatic filter press

    Auto Diaphragm Filter Press for sludge Dewatering | effluent treatment plant Pressure 1.2Mpa

    Our new diaphragm filter press are widely used in waste water or slurry treatment, industries from plating and metal finishing to chemical and food processing. Our filter Presses feature heavy duty steel construction with polypropene gasketed plates. These filter presses can be manufactured with manual or automatic closures, but always with a hydraulic cylinder for sure, high pressure closing. The filter pressescan be expanded for larger future capacity by building it in a larger skeleton with a distance piece.  Once you are ready to expand, you can remove the distance piece  and add the extra plates.


    The diaphragm filter press comprises a set of vertical, juxtaposed recessed plates, presses against each other by hydraulic jacks

    at one end of the set. The pressure applied to the joint face of each filtering plate must withstand the chamber internal

    pressure developed by the sludge pumping system.
    This vertical plate layout forms watertight filtration chambers allowing easy mechanisation for the discharge of cakes.

    Filter chlotes finely or tightly meshed are applied to the two groowed surfaces in these plates. Orifices feed the sludge to

    befiltered under pressure in the filtration chamber. They are usually placed in the center of the plates allowing a proper

    distribution of flow right pressureand better drainage of sludge within the chamber.Solid sludge gradually accumulate in

    the filtration chamber until the final compacted cake is formed. The filtrate is collected at the back of the filtration

    support and carried away by internal ducts.

    Filtration cycle

    The filter press is an intermittent dewatering process. Each press operation includes the following steps:

        Closing of the press: as the filter is completely empty, the moving head activated by the jacks calmps the plates.
        Closing pressure is self regulated through filtration
        Filling: During this short phase chamber are filled with sludge for filtration. Filling time depends on the flow of the
        feed pump. For sludge having good filterability it is best to fill the filter very quickly so as to avoid the formation
        of a cake in the first chamber before the last ones have been filled.
        Filtration: Once the chamber have been filled continuous arrival of sludge to be dewatered provokes a rise in
        pressure due to the formation of an increasingly thick layer of filter sludge on the cloths. This filtration phase can
        be stopped manually, by a timer or more convenientely by a filtrate flow indicator which issues a stop alarm when
        the end of filtration rate has been reached. When the filtration pump has stopped, the filtrate circuits and central
        duct, which is still filled with liquid sludge, are purged by compressed air.
        Filter opening: The moving head is drawn back to disengage the first filtration chamber. The cake falls has a result
        of his own weight. A mechanised system pulles out the plates one by one. The speed of plate separation can be
        adjusted to account to the cake texture.
        Washing: Whasing of clothes should be carried out every 15-30 processing oprations. For mid- or large units this
        take place on press using water sprayers at very high pressure (80-100 bar). Whasing is sincronized with separation
        of plates.

    Filtration capacity

    The production capacity of a filter press is somewhere between 1.5 and 10 kg of solid per m2 of filtering surface.

    every the filter press model the chamber volume and the filtering surface depend on the number of plates in the


    In practical terms pressing times are less then four hours. 
    Filtration time depends on:

    • cake thikness
    • sludge concentration
    • specific resistance
    • compressibility coefficient.

    One of the advantages of the filer press is that it can accept sludge with average filterability. It is always advantageous to

    optimally thicken sludge before filter press operations. Although sludge presenting a high filterability enables better production

    capacities, a filter press still accepts sludge with low conditioning precision. This tolerance means that the device offers

    greater owerall operational safety.

    The filter press is suitable for almost all types of sludge:

        Hydrophilic organic sludge: inorganic conditioning is often recommended to enable satisfactory cake release due to minimal
        aderence to filter cloth.
        Hydrophilic inorganic sludge: the filer press generally requires the addition of lime only.
        Hydrophobic inorganic sludge: it is very dense and ideal for the filter press. It is dewatered without any preliminary conditioning.
        Oily sludge: the filter press can be used to treat sludge containing light oils, the presence of grease can sometimes impair the
        smooth running of the filter; clothes have to be degreased at frequent intervals.
