This research assessed membrane integrity monitoring methods for microfiltration (MF) and ultrafiltration (UF) membrane filtration processes. The project evaluated existing and newly developed methods for integrity monitoring using literature review and full-scale testing of the essential criteria of sensitivity, continuity, identifiably, reliability, and implementability. Recommendations are included. While this research was motivated by the USEPA's LT2ESWTR, the coverage and results have international applicability.... pressure decay testing, particle counting, and monitoring could be considered aquot; routineaquot; methods for detecting small to moderate levels of integrity breach; and bubble point, manual sonic, and manual pressure decay could be considered as aquot;diagnosticaquot; methods for ... When using membrane systems with air-backwash, this method should be considered as a candidate monitoring method (if not alreadyanbsp;...
