The separator device includes a receptacle with an upper first part and a lower second part separated by a plate. The receptacle further has an inlet port for waste water, a discharge port for separated waste water, discharge means for grease and/or sludge, and an overflow pipe establishing a connection between the receptacle first part and the receptacle second part. Waste water is supplied through the inlet port to the upper first part, and the waste water is allowed to undergo a separation by gravity, whereby a grease layer is formed on a separated waste water layer and a sludge layer on the plate. In order to achieve a high degree of separation, separated waste water is allowed to flow through the overflow pipe to the receptacle lower second part. Grease is removed from the grease layer and/or sludge from the sludge layer through the discharge means, and separated waste water is discharged through the discharge port.Field of SearchIncluding change of mainstream flow directionIncluding specified feature of settled solids removal Utilizing gravitational force Superposed compartments or baffles, e.g., parallel plate type Each with lighter constituent discharge Heavier constituent trap, chamber, or recess In sloping recess Downstream of separator In side wall of separator With discharge means for two or more lighter constituents Lighter constituent trap Gas vent or bypass With discharge port Within gravitational separator One unit supports another On different levels Level sensing Responsive to material level | |
