Working principle of plate and frame filter press: used for separation of solid and liquid. The mud cake filtered by pressure filter has higher solid content and better separation effect. The basic principle of solid-liquid separation is: the mixed liquid flows through the filter media (filter cloth), and the solid stays on the filter cloth, and gradually accumulates on the filter cloth to form filter cake. The filtrate is not permeated by the filtrate.
