Figure 7 Large-scale pressure characterization results. Schematic representation of the experimental setup for the large-scale pressure characterization in water (A). Pressure transmitters (PT), flow sensors (FS), centrifugal pumps (CD) and peristaltic pumps (PP) are specified with subscripted letters according to their position (R: Retentate; F: Filtrate; A and AB: Additional sensors on filtrate side; H: Harvest). Picture of experimental setup (B). Large-scale crossflow ramping in TFF operation (C) and crossflow ramping with delta pressure control in HPTFF operation (D). Pressure measurements according to their position along the filter length are provided for TFF (E) and for HPTFF (F) at standard operation of 1470 s-1 shear, grey areas represent absolute fiber length.
