ABSTRACT:
A water recycle unit for producing clear water output from grey water input comprises an enclosed container which holds a relatively large volume of water within the container while the heavy materials of the grey water, such as sand and dirt, settle to a lower zone and the lighter materials, such as oil and fibers, rise to an upper zone leaving a central zone of clear water between the lower and upper zones. An internal gate within the container removes clear water from the central zone through the outlet in response to the inflow of additional grey water into the unit through the upper inlet. The outlet is located in a side wall above the level of the central zone of clear water, and the gate includes an inlet opening which is located in the central zone. The gate also includes a passageway between the inlet opening and the outlet for conducting only clear water from the central zone to the outlet. Internal, vertical partitions direct flow within the container and also prevent any turbulence produced by the incoming grey water from being mixed with the clear water existing in the central zone adjacent to the gate inlet opening. The water recycle unit also includes a clear water collector and filter box. This box is an enclosed structure which is preferably joined integrally to one side wall of the container. It includes a spillway for collecting the water which flows out of the outlet of the container and for directing that clear water through a filter.
