A liquid solid separator tank has a motor driven recirculating belt having rollers placed therein processing a mixture of materials. The top belt brings wet materials into a collection trough having overflow weirs disposed externally. These weirs permit overflow liquids to flow down towards a main tank; then, a sump pump reintroduces water back into an influent basin to cleanse the mixture once again. Also, the action of a motor driven auger within the trough forces solids towards a dewatering box attached externally thereto. This box has a motor driven rotating cage mounted on moveable rollers and internally attached removable brushes that act to clean the outer surface of the cage as it moves in addition to a stationary high pressure wash. A shroud channels the influent liquid solid mixture towards a filtered water basin disposed directly underneath the lower belt portion permitting cleansed water to be removed therefrom.
