Chamber filter presses operate by compressing a series of filter plates and frames together to form a series of chambers. The chambers are then filled with slurry, and the liquid passes through the filter cloth and out of the press. Membrane filter presses, on the other hand, have a flexible membrane that is attached to the filter plate. When the chamber is filled with slurry, the membrane is inflated with compressed air, which applies pressure to the slurry, and the liquid is forced through the filter cloth and out of the press.

Membrane filter presses typically provide higher filtration efficiency than chamber filter presses. This is because the membrane can apply additional pressure to the slurry, forcing more liquid out of the filter cake. Additionally, the membranes can be washed during the filtration process to ensure that the cake is completely dewatered.

Membrane filter presses typically provide drier filter cakes than chamber filter presses. This is because the membrane can apply additional pressure to the slurry, forcing more liquid out of the filter cake. Additionally, the membranes can be washed during the filtration process to ensure that the cake is completely dewatered.

Membrane filter presses tend to have a smaller footprint than chamber filter presses. This is because they can operate at higher pressures, which allows for smaller filter plates and frames.

In general, membrane filter presses tend to be more expensive than chamber filter presses. This is because they require additional equipment, such as the inflation system for the membranes, and are typically more complex to operate.
