Abstract
A standard flux-step method has been developed for assessing fouling in а membrane bioreactor operating at constant flux. Three keys parameters based on transmembrane pressure (TMP) were derived to depict fouling behaviour and identify the onset of fouling at the critical flux. The three TMP-based parameters all indicated roughly the same flux value at which fouling started to become significant. It was concluded that flux-step determination of the critical flux cannot be used to predict long-term TMP behaviour in real MBR systems, but nonetheless provides useful data on comparative fouling propensity.
