PP filter press, recessed filter press, chamber filter press

Recessed chamber filter presses are one of the most efficient ways to dewater and compact sludge into disposable cakes. Depending on the nature of the slurry, our filter presses are capable of dewatering sludge up to 30 to 60 percent solids. The sludge slurry is generally pumped into the press with an air diaphragm pump. The sludge slurry fills the recessed chambers and dewaters via the pressure from the feed pump. Filtrate passes through the media/filter cloth and continues out of the press. Our filter presses produce clear filtrates and high percentage solids.

Working principle,

The liquid solid mixture is pumped into the filter press, which is made up of a number of recessed filter plates forming chambers. The plates are supported in a fabricated steel frame and is held closed by a force exerted from a hydraulic ram mounted in the frame work at the end of the machine.

Each filter plate is covered by a filter cloth that retains the solid particles, but allowing the liquid to pass through and exit through the ports in the filter plate.

The particles retained gradually build up on the surface of the filter media and after a period of time eventually form a solid cake.

As the cake forms the pressure within the filter press the pressure rises as the filtrate has to pass through the already partially formed cake to exit the chamber. It becomes increasingly more difficult to continue pumping as the press is unable to accept more solids. At this point the feed pump is stroking infrequently and the filtrate flow from the filter press has considerably reduced or completely stopped.

At this point or at a predetermined filtration time or pressure being achieved the cycle is terminated and the fully formed filter cake is discharged.
