Rotary Drum Filters

This machine is of the rotary drum filter type but the filtering medium is applied on the interior of the drum which acts as its own container The inner surface of the drum is divided into a series of fabric-covered panels each forming a face of a polygon inscribed within the cylinder The compartments thus formed connect individually with an automatic valve which in turn applies vacuum
