This powerpoint presentation begins by providing background information on the integrity monitoring methodology for microfiltration/ultrafiltration (MF/UF) membranes. The objectives of the study were to have a decision-aid tool for operators that:gives them the integrity level of their plant without having to disconnect all themodules; and, thatindicates whether the measured level effects plant effectiveness, requiring immediate repair. Methods included:developing a model that uses the air flow rate throughout a defect during theair pressure test for predicting the microbial Log Removal Value (LRV) of the unit;conducting challenge tests with MS2 phages with various calibrated defectson the membrane fibers at bench-scale in order to validate the model and the selectedassumptions; and,evaluating the validity of the model at full-scale. Includes figures.
