Abstract
A machine for separation two liquids of different densities from a mixture has a separation chamber with radially disposed fins that rotates about a central axis. The separation chamber has an outside wall with a first weir extending toward the central axis and spaced from the central axis a distance or radius that is less than the distance of the boundary between the two fluids in the separation chamber. The mixture separates into a first volume of the first fluid and a second volume of the second fluid. The first fluid exits past the first weir. The second fluid passes into a channel or volume and then past a second weir. The channel or volume is sized so that the angular momentum of the second fluid is conserved and develops a force to retain the first fluid and the second fluid in the separation chamber. The separation chamber is in a housing which contains a first collecting chamber to collect the first fluid and a second collecting chamber to collect the second fluid. Other arrangements are available to remove gas entrained in the mixture and solids such as sludge entrained in the mixture.
