Chamber Filter-Presses

Chamber filter-presses of different designs with vertically set polypropylene plates and filtration surface from 0,7 up to 2000m2.

Chamber filter-presses are the modern equipment for effective separation of solid and liquid phases of medium- and poor-pressing suspensions in chemical, mining, coal, ceramic, food (sugar) and other industries.

The main operation performed by a chamber filter press:
• filtration;
flushing of sediment;
drying the sludge;
scavenging collector;
discharge of sediment.

The other fields of application of filter-presses:

Food industry:
dehydration of grain mash;
production of starch, aspartame and their derivatives;
production of beer, wine, etc.

hemical industry:
mineral fertilizers;
copper sulphate;
sodium carbonate, carbon white, etc.

Mining industry, hydrometallurgy:
concentrates of metals (Fe, Cu, Pb, Zn, Pt, Sn, Co, Ni, pyrite, etc.);
washing and drying of metal sludges;
alumina, kaolin, chemically purified chalk, limestone, silicates, feldspar,
thickening of "tails", etc.

dewatering of residential sewage;
treatment of industrial waste waters of galvanic and chemical factories, etc.

As an example it is represented a chamber filter press of Joint Russian-Chinese manufacture with a filtration surface 150m2

The advantages of this filter are:

Full automation of the process of filtering based on microprocessor;
simple to operate and maintain automation;
hydraulic membrane wringing of sediment (not required compressor and receiver as in the case of a pneumatic wringing);
the washing device for regeneration of filtering cloth directly on the filter;
effective discharge device: filter discharge time reduced to 7 minutes;
increased to 50 mm depth of the chamber, which increases productivity by 10-12%;
you can adjust the speed of plates movement;
in addition filters can be equipped with "a light curtain»;
electronics of Siemens;
low price.

Filtration equipment is manufactured in strict accordance with national and international standards.

Standard series of polypropylene filter plates (chamber-filters, membrane filters with a fixed membrane,

membrane filters with a removable membrane): from 420x420 mm to 2000x2000 mm.

Plates allow to obtain a sediment`s thickness from 20 to 60 mm and work under pressures up to 3,5 MPa.

For separation of hot slurries (with temperatures above 60°C) plates are made with addition of special filler – non-alkaline fiberglass.

These filter plates are used by the leading manufacturers of filter-presses.
