On the rejection and reversibility of fouling in ultrafiltration as assessed by hydraulic impedance spectroscopy

[EN] The manifestation of critical fluxes in membrane filtration has typically served to set an upper value above which detrimental fouling events and a substantial increase of membrane resistance occurs. Despite the usefulness of critical flux concepts for conducting sustainable membrane processes,...
