Advantages of  Variable Volume Membrane Filter Presses

Reduced Cycle Time

Conventional fixed volume filter presses filter only 75 to 80% of a given batch in the first 50% of the cycle time. If the plate stack is opened before the full cycle is complete, the result is a wet sloppy cake. The cycle of a variable volume membrane filter press, however, can be stopped at its most efficient point. By applying pressure to the membrane built into the filter plate, the cake is squeezed to produce a high-solids filter press cake in a significantly reduced cycle time.

Superior Cake Washing

The Avery variable volume membrane filter press improves cake washing efficiency and reduces wash time by applying a low-pressure pre-squeeze before the wash cycle is begun. This pre-squeeze produces a uniform filter cake, eliminating wash liquid channeling through cracks and less well formed areas of the cake.

High Cake Solids

By applying a high pressure membrane squeeze to the formed filter cake with pressurized fluid (up to 225 psi or higher), it is possible to produce a final cake with solids content from 50% to 100% greater than can be achieved with conventional fixed volume filter presses. This is important for obtaining maximum yield, where a high-value liquid is your product, or producing a high solid content cake, where it is critical to reduce moisture content.
