ABSTRACT:
A mobile separator system for receiving and separating a mixed composition of oil, water, and sludge. The mobile separator system including a tank for holding the mixed composition, and a drain manifold that includes a plurality of drain pipes extending into the tank at varying elevations for allowing the drainage of water from the tank system. A vacuum source is attached to the top of the tank for carrying a vacuum within the tank to draw the mixed composition into the tank. The drain manifold is surrounded by a screen that allows the passage of water and oil, while preventing the passage of sludge through the screen into the drain pipes. A floating check valve is connected to each of the drain pipes to regulate the flow of water through the drain pipe. The floating check valve includes a valve element that has a density which causes the valve element to float in water and sink in oil. Therefore, when the valve element is surrounded by oil, the drain pipe will close and impede the passage of oil through the drain pipe. The water is then able to be drained using each drain pipe, with the highest pipe draining the water first, then the next highest, and so on until the water is drained from the tank.
