Filter Press System

Filter presses are sometimes called "Plate-and-Frame Filters."The primary usage of a filter press is as a "fixed volume, batch pressure filter." As a fixed volume filter, it is built to hold a specific quantity of solids. The filter press may also be used as a "polishing" filter to remove minute quantities of solids from an in-fluent stream.

Sometimes it is the fluid, the filtrate, which is the product, in other cases the filter cake.
