Filter Plates: Vacuum Membrane Plates

For completely dry filter cakes!

Vacuum/Membrane filter plates have a chamber below the drainage surface that is inflated after the filter cake is formed. Heated water 175F°-230F° (higher temperatures may be used with metal cores) is pumped through this cavity, both inflating the membrane against and transferring heat into the filter cake.

A constant pressure is generated by water flow, which keeps the membrane face against the filter cake as it shrinks during the drying process. A vacuum applied within the filtration chamber draws out moisture from the filter cake and will, with sufficient time, produce a bone dry product.
