  • Patent number: 11717790
    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).

  • Publication number: 20230193188
    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.

  • Publication number: 20220403318
    Abstract: The present subject matter discloses a bioreactor apparatus. The bioreactor apparatus comprises a bioreactor vessel configured to culture cells. The bioreactor apparatus furthermore comprises a sensor configured to measure Dissolved Oxygen (DO) in the bioreactor vessel. The DO measurements comprise a plurality of DO values recorded at, at least, a plurality of time instances during operation of the bioreactor apparatus. The bioreactor apparatus furthermore comprises a controller configured to obtain the DO measurements. The controller furthermore is to determine, in real-time or approximately real-time, an oxygen mass transfer co-efficient (kLa) associated with the operation of the bioreactor apparatus. Furthermore, the controller is configured to control, in real-time or approximately real-time, at least one cell culture parameter associated with the operation of the bioreactor apparatus based on the kLa.
