Claim 11:
12. 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,
wherein the concentrate pump chamber is in fluid communication with the separation chamber through a substantially annular concentrate opening,
wherein the centrate pump chamber is in fluid communication with the separation chamber through a substantially annular centrate opening, wherein the substantially annular concentrate and centrate openings are coaxial and the substantially annular concentrate opening is disposed radially outward from the substantially annular centrate opening,
a continuous annular centrate dam,
wherein the annular centrate dam
extends in the separation chamber,
extends downward below the substantially annular centrate opening, and
is disposed radially outward of the substantially annular centrate opening,

a continuous annular concentrate dam,
wherein the annular concentrate dam
extends in the separation chamber,
extends downward below the substantially annular concentrate opening, and
is disposed radially inward of the substantially annular concentrate opening.
