Abstract
An apparatus for separating an immiscible or insoluble fluid mixture into its components, namely, a less-dense component and a denser component, is described. The apparatus may be used in commercial kitchens to separate grease-oil/water mixtures into a grease-oil component and a gray water component, the grease-oil being diverted to a receptacle for subsequent disposal and the gray water component being directed to a drain or sewer. The apparatus may be described as a pump/separator when attached to a vacuum source or a pump to assist with filling. Additionally, a compressed gas source may be attached to the apparatus to assist with the discharge of the denser component and the less dense component. The apparatus may include a controller, such as a microprocessor, to coordinate filling, separation, and discharge. Parallel and serial arrangements of the apparatus are shown.
