The Chamber filter press or membrane filter presses have been used in a variety of 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.
A plate 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.
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

The production capacity of a filter press is somewhere between 1.5 and 10 kg of solid per m2 of filtering surface. For
every the filter press model the chamber volume and the filtering surface depend on the number of plates in the filer.
In practical terms pressing times are less then four hours.
Filtration time depends on:
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.
Pipe line diagraphm
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.
