Classification: CPC B  C | IPC B

Claim 7:
8. The apparatus according to claim 1
wherein the single use structure further includes:
a vertically extending concentrate discharge tube,
wherein during rotation of the bowl, the upper disc shape portion and the outer wall rotate relative to the concentrate discharge tube,

a concentrate centripetal pump, wherein the concentrate centripetal pump is
axially aligned with the core,
disposed coaxially about the feed tube,
vertically positioned above the centrate centripetal pump,
in fluid communication with the concentrate discharge tube, and
positioned in a concentrate pump chamber, wherein the concentrate pump chamber is in fluid communication with the separation chamber,

wherein during rotation of the bowl the upper disc shape portion and the outer wall rotate relative to the concentrate centripetal pump,
and further comprising:
an external concentrate pump, wherein the external concentrate pump is outside of the single use structure and is in fluid connection with the concentrate discharge tube,
a concentrate optical density sensor, wherein the concentrate optical density sensor is in operative connection with an interior of a concentrate discharge line, wherein the concentrate discharge line is in operative connection with the concentrate discharge tube and the external concentrate pump,
an external centrate pump, wherein the external centrate pump is outside of the single use structure and is in fluid connection with the centrate discharge tube,
a centrate optical density sensor, wherein the centrate optical density sensor is in operative connection with an interior of a centrate discharge line, wherein the centrate discharge line is in operative connection with the centrate discharge tube and the external centrate pump,
a controller, wherein the controller is in operative connection with the external centrate pump, the external concentrate pump, the centrate optical density sensor and the concentrate optical density sensor, wherein the controller is operative to control at least one of the external concentrate pump and the external centrate pump responsive at least in part to the concentrate optical density sensor and the centrate optical density sensor.
