Data for "Development of a versatile testing apparatus for measuring hollow fiber membrane flux and permeance"

DescriptionThis dataset accompanies the publication "Development of a versatile testing apparatus for measuring hollow fiber membrane flux and permeance" and includes experimental data used to produce the figures in the article. The study presents a new device that can measure the flux and permeance of individual or multiple hollow fiber membranes in both the outside-in and inside-out orientations, partnered with a python-based open-source permeance analysis software. Additionally, the device is used to study compression and fouling of hollow fiber membranes in both outside-in and inside-out orientation in dead-end mode, with behaviour differences observed dependent on membrane orientation.Publication DetailsWhen using this data, please cite: Timothy Warner, Shrisha Srinivasa, Nathan Mullins, et al.
