Abstract: A component management apparatus for a bioprocessing system includes a frame having a plurality of segments, including at least a first segment and a second segment pivotably connected to the first segment such that at least the second segment is movable between a closed position and an open position, and at least one mounting bracket connected to the frame for connection of a bioprocess component.

Abstract: A method includes measuring, by a flow sensor (70), a flow rate of a permeate fluid (48) flowing through a filter (20) of a membrane filtration system (12). Further, the method includes receiving, by a control unit (86), the measured flow rate of the permeate fluid (48) and determining, by the control unit (86), a first flux rate of the filter (20) based on the measured flow rate of the permeate fluid (48). Furthermore, the method includes comparing, by the control unit (86), the determined first flux rate with a first predetermined flux rate. Additionally, the method includes operating the membrane filtration system (12), by the control unit (86), in a normal mode or a flux tolerant mode based on the comparison of the determined first flux rate with the first predetermined flux rate. The flux tolerant mode of the membrane filtration system (12) is further based on a determined normalized water permeability value of the filter (20).

Abstract: A bioprocessing system (100, 200) including a storage unit (102, 202) for storing a feed fluid (103, 203), a filter (106, 206) coupled to the storage unit (102, 202) via a feed path (104, 204), and a feed pump (114, 212) coupled to the feed path (104, 204). The bioprocessing system (100, 200) further includes a collection unit (102, 216) coupled to the filter (106, 206) via a downstream path (118, 218) and a turbidity sensor (134, 224) coupled to the downstream path (118, 218). Furthermore, the bioprocessing system (100, 200) includes a processing unit (136, 226) configured to receive an output from the turbidity sensor (134, 224) and determine a concentration of a product in a filtration fluid (121, 222) based on the output. The processing unit (136, 226) is further configured to monitor an operating condition of the filter (106, 206) on-line based on concentration of the product.
