Abstract:
1. An apparatus for separating a brine, comprising: a casing having a centerline, the casing comprising an axial feed port and an axial exhaust port, both ports being coaxial with the centerline; a rotatable centrifugal pump disposed within the casing and connected to a driver, the centrifugal pump having an axis of rotation at said centerline and the centrifugal pump configured to draw brine into the casing through the axial feed port; a tank communicating with the interior of the casing and configured such that brine from the axial feed port, when advected radially outward from the centerline by the centrifugal pump, collects and concentrates in the tank; a rotatable baffle disposed between the axial feed port and the axial exhaust port and spaced apart from the casing so as to define a high-shear radially inward sink flow passage for water from the brine to be extracted from the casing through the axial exhaust port; and at least one radio frequency bifilar pancake coil adapted to repel brine from flow in the sink flow passage into brine advected radially outward by the centrifugal pump when the apparatus is operative, the coil disposed above the sink flow passage.
