Claim 11:
12. The apparatus according to claim 10
wherein the centrate centripetal pump includes a substantially annular centrate pump opening, wherein centrate from the centrate pump chamber enters the centrate centripetal pump through the substantially annular centrate pump opening,
wherein the substantially annular centrate pump opening is radially disposed away from the axis a centrate pump opening distance,

wherein the centrate centripetal pump chamber is bounded vertically by a lower circular axially centered centrate centripetal pump chamber surface and an upper axially centered circular centrate centripetal pump chamber surface,
wherein at least one of the lower centrate centripetal pump chamber surface and the upper centrate centripetal pump chamber surface includes a plurality of angularly spaced, radially and vertically extending centrate chamber vanes, wherein the centrate pump chamber vanes extend radially outward from the axis and terminate outwardly from the axis at a centrate vane distance,
wherein the centrate vane distance is less than the centrate pump opening distance.
