Quick answer: Changzhou Senjie builds chamber (recessed-plate), membrane and plate-and-frame filter presses from 630 mm to 2000 mm plate size, in manual, semi-automatic and fully automatic versions, for mining tailings and concentrate, municipal and industrial sludge, chemical, food and stone-processing slurry.
How to use this catalog: choose the chamber filter press for general dewatering where a 60–75% moisture cake is acceptable; the membrane filter press when you need a drier cake or a shorter cycle; the plate-and-frame press for small batches, thin cakes or intact cake removal; and the tailings press or concentrate press for continuous mine duty.

Filter Press Catalog - Chamber, Plate and Frame, Membrane

Which filter press type should you choose?

The right filter press depends on how dry the cake must be and what the slurry is. The table compares the three main types Senjie builds.

TypeHow it dewatersTypical useChoose it when
Chamber filter pressFeed-pump pressure fills recessed chambers and forms the cakeMunicipal and industrial sludge, mining tailings, general dewateringYou want a simple, robust press and standard cake dryness is acceptable
Membrane filter pressFeed pressure plus a membrane squeeze stageConcentrates, chemicals, food, sludge with a strict moisture limitCake must be drier or the cycle must be shorter
Plate and frame filter pressSlurry is filtered between flat plates and hollow framesFine filtration, polishing, frequent cloth or paper changesFiltrate clarity matters more than cake volume

Filter press buyer questions

What is the difference between a chamber filter press and a membrane filter press?

A chamber filter press dewaters with feed-pump pressure alone. A membrane filter press adds a squeeze stage: after the chambers are full, a flexible membrane is inflated with air or water and presses the cake again, which gives a drier cake in a shorter cycle.

Which filter press type gives the driest cake?

A membrane filter press normally gives the driest cake, because the squeeze stage removes water that feed pressure alone leaves behind. Sludge conditioning, filter cloth selection and cycle time also affect the final moisture.

What information is needed to size a filter press?

Five figures: slurry volume per day, solids concentration, target cake moisture, operating hours per day, and particle size and pH. From these the cake volume per cycle, plate size and number of plates can be calculated.

Does Senjie also supply filter plates and filter cloth?

Yes. Changzhou Senjie Environmental Equipment Co., Ltd. supplies filter presses together with filter plates, filter cloth and feed pumps, so the press, plates and cloth can be matched to the same slurry.
