  • Patent number: 4867877
    Abstract: A waste removal and/or segregation system for removing liquid and solid waste simultaneously from waste-holding tanks or vessels. The solid matter in the waste is filtered or segregated into one holding area and the liquid waste placed in a separate holding vessel so that each waste material may be independently disposed of in accordance with current EPA requirements. A separation or filtration element is interposed between a conventional liquid waste removal system including a container for the liquid waste and the nozzle applied to the waste material containing both solid and liquid matter. This vessel has an inlet connected to the nozzle and an outlet connected to the vacuum source through the liquid waste storage tank. The novel vessel of this invention has a filtration system that permits the liquid waste to exit for independent disposal while retaining solid matter for independent disposal.
