These support sheets can provide pre-coated support for any filter press. Use these sheets when you want to recover valuable materials or insoluble contaminants (such as protein deposits) in large-volume beverages or high-particle-load beverages. The so-called diatomaceous earth pre-coated plates use classic sheet and frame filters. The continuous formation of diatomaceous earth deposits on the surface of these support sheets represents an effective filter medium, which is an ideal choice for clarification, refining filtration, and removal of colloids. We provide multiple formats.
