Plate and frame filter press working principl:

The filter press is used for the separation of solids and liquids. Compared with other solid-liquid separation equipment, the filter cake after filtration has a higher solid content and excellent separation effect. The basic principle of solid-liquid separation is: the mixture flow through the filter media (filter cloth), solid stay in the filter cloth, and gradually stacked on the filter cloth to form a filter cake. And the filtrate portion permeates the filter cloth and becomes a solid-free solution.

With the filtration process, filter cake began to filter, mud cake thickness gradually increased, increased filtration resistance. The longer the filtration time, the higher the separation efficiency. Specially designed filter cloth can be retained particle size less than 1μm particles. In addition to the excellent separation effect and mud cake high solid content, but also provide a further separation process:

Box filter preess in the process of filtering can be combined with the filter cake for effective washing.
