Abstract
A process and device for the filtration of solid-liquid mixtures, in particular, solid-liquid suspensions with readily sedimenting substances, uses a filtration device such as a rotary filter optionally operating at an overpressure and in a pressure vessel. The process primarily comprises producing a movement in addition to the natural or usual filtration movement of the or in the mixture. Conveniently, a filtration device and, in particular, with rotary filters in a pressure vessel, includes a partly open feeding device, in particular, a feeding pipe for the supply of mixture or suspension, and a device for additionally influencing the natural or usual filtration movement of or in the mixture or suspension for generating an additional flow of the mixture.
