Abstract
A method and device for separating grease from waste water. 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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
