The invention relates to a method for separating grease from waste water by means of a separator device. The separator device comprises a receptacle (1) with an upper first part (5) and a lower second part (7) separated by an intermediate plate (6,6a). The receptacle is further provided with an inlet port (8) for waste water, a discharge port (18) for separated waste water, discharge means (10,25) for grease and for sludge, and an overflow pipe (12) establishing a connection between the first part (5) and the second part (7). Waste water is supplied through the inlet port (8) to the upper first part (5) and the waste water is allowed to undergo a separation by gravity, whereby a grease layer (GL) is formed on a separated waste water layer (WL) and a sludge layer (SL) is allowed to settle on the intermediate plate (6,6a). In order to achieve a high degree of separation, separated waste water is allowed to flow through the overflow pipe (12) to the second lower part (7) of the receptacle (1). Grease is removed from the grease layer (GL) and/or sludge from the sludge layer (SL) through the discharge means (10,25) and separated waste water is discharged through the discharge port (18). <IMAGE> |
