Abstract: A liquid recovery system and methods of recycling water from liquid-solid mixture such as slurry produced by pavement grinding machines, drilling fluid containing cuttings, and septage. The system includes a storage tank or a settling tank, a centrifuge in flow communication with the storage tank or settling tank, such as a hydraulic centrifuge, a solids storage component, and a cleaned liquid storage tank in flow communication with the centrifuge. The system may also include a porous conveyor belt for removal of large solids from the mixture prior to centrifugation and may also include one or more blowers directed at the porous conveyor.
