filter press

A filter press is a piece of equipment used for filtration. It typically consists of a series of corrugated plates with a filter medium between them, all assembled in a framework. A suspension is forced under pressure into this assembly, causing solids to collect as a cake between the plates while the liquid passes through. Filtration itself is a process that separates solid particles from a liquid or gas using a filter medium. This process requires a filter medium, the fluid with suspended solids, a driving force like pressure, and a mechanical device to hold the medium and contain the fluid. Filter presses are a type of batch-operated pressure filter, often used when continuous filtration equipment isn't warranted.12
