Solid liquid separation is a standard task in modem chemical industry. Therefore various different technologies and equipment exist for this task. However, especially for cut sizes in the micron range all of the existing devices show drawbacks, e.g. regarding separation sharpness, throughput, yield of fines, etc. This article describes a novel device for solid-liquid separation with cut sizes in the micron range which was built to close the gap of solid-liquid separation equipment in the micron range. The operating principle and design concept of the device are explained, its separation performance for standard slurries and different operating conditions as well as degrees of freedom and optimisation strategy are outlined.
