A Membrane Filter Press is fed in the same way as a chamber filter press. However, The increasing feed pressure ensures pre-compression and dewatering of the filter cake in the chamber. As soon as the feed pressure has reached the predetermined value (approx. 6-8 bar), the filter cake is squeezed again accordingly. The flexible membranes (e.g. filled with compressed air or water) press the filter cake solid onto the chambers’ entire surface, which compresses and thus expels free water over the filter cloth.
A membrane filter press has further configuration options to choose from to achieve an even higher filtration quality. These include, for example, filter cake washing, filter cake dry blowing, core rinsing and core blowing. During filter cake washing, however, the filter cake must be pre-pressed, which stabilizes the filter cake and thus prevents shrinkage cracks. After completion of the filtration process, the chambers are emptied. The closing pressure of the filter press is released, the filter press is opened, and the Cake is removed from the filter cloths. The filtration cycle is then repeated.
We manufacture membrane filter presses. The membrane squeeze plate is offered to suit up to 16 bar squeezing pressure. Due to additional liquid extraction from the Cake during the squeeze cycle, moisture in the Filter Cake reduces, and filtration cycle times are reduced compared to the conventional recess.
The machine consists of a larger plate and Automatic filter press with mechanical plate shifters. Corner feed plates are incorporated into the filter press design. The plate shifter moves the plates and allows rapid discharge of filter cakes accumulated in between the plates. And other is : Filter Cloth Selection
