Provided is a centrifuge media separator for separating blast particulate from fine particulate carried by air flowing from a blast cabinet and through the media separator. The centrifuge media separator comprises an upper panel, a lower panel, and an outer wall. The upper panel has a central opening formed therein. The outer wall is configured in a truncated logarithmic shape and which extends between the upper and lower panels. The outer wall has at least one particulate escape aperture formed therein. The upper panel, lower panel and outer wall collectively define a curvilinear air passageway having an inlet and an outlet. An air foil extends from the outer wall in to the air passageway. The distance than the air foil extends in to the air passageway is adjustable. The inlet is configured to allow a flow of air to enter the air passageway and circulate therethrough toward the outlet. The escape aperture is configured to exhaust the blast particulate out of the passageway. The central opening is configured to exhaust the fine particulate out of the passageway.

A method and apparatus for separating cell suspension into centrate and concentrate includes a solid wall rotatable centrifuge bowl (82). A single use rotatable core (88) is positioned in the bowl and bounds a cavity (90) which serves as a separation chamber. The bowl rotates about an axis (84). An inlet tube (92) and an outlet tube (102) extend along the axis in the bowl cavity. The centripetal pump (98) in the cavity is in connection with the outlet tube. The centrate discharge pump (120) is in connection with the outlet tube. A pressure damping reservoir (122) is fluidly connected between the outlet tube and the discharge pump. At least one control circuit (142) is operative to control the apparatus to maintain a positive pressure above atmospheric pressure within the cavity, so as to maintain the cell suspension away from at least one seal (106) that bounds the interior of the cavity.

The invention relates to a rotodynamic separator (30) for separating a liquid and a gas from a multiphase fluid, notably for use in the petroleum industry. This separator comprises a cylinder (12) freely rotating about an axis (xx), a substantially axial inlet (1) for the multiphase fluid, a liquid outlet (5) and a gas outlet (6). At least one vane assembly (15) arranged along axis (xx), in the direction of circulation (F) of said multiphase fluid, is installed and integral with cylinder (12). Vanes (15) are directed towards axis (xx) of cylinder (12). Furthermore, the inside diameter of vanes (15) decreases progressively, in the part of the separator located upstream from the outlet of the second phase, in the direction of circulation of the multiphase fluid, while remaining larger than the inside diameter of gas outlet (6).

A centrifugal separator includes disposable cartridge having a cylindrical bowl, a core tube assembly, and an annular piston disposed around the core tube assembly and inside the inner surface of the bowl. The disposable cartridge may be automatically loaded and withdrawn from the separator. Feed liquid is injected down the core tube assembly into the lower portion of the bowl, raising the annular piston, while the bowl rotates at high speed, separating solids from the feed liquid to accumulate along the inner surface of the bowl, while collecting clarified centrate as it exits the top of the bowl and through the core tube assembly. In a solids discharge mode, the annular piston is urged downward along a vertical axis to force accumulated solids from the bowl.
