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.

Abstract: A mobile water recovery system and methods of recycling water from slurry produced by pavement grinding machines. The system includes a platform having a plurality of wheels, a slurry storage tank or a slurry settling tank, a centrifuge in flow communication with the slurry storage tank or slurry settling tank, such as a hydraulic centrifuge, a solids storage component, and a cleaned water storage tank in flow communication with the centrifuge. The system may also include an acidifier which may be located within the cleaned water storage tank. The acidifier may bubble engine exhaust through the cleaned water or may dispense a pH adjusting agent into the clean water storage tank.
