This powerpoint presentation begins by presenting project objectives that include the following: to determine the impacts of the ultrafiltration (UF)design on the hydrodynamics; and, to determine the consequences onthe fouling and the clogging. The methods included: develop and optimize CFD tool tocharacterize the hydrodynamics of an ultrafiltrationmodule by monitoring the distribution of inlet water in the connectionbox;assess results of the CFD modelingthroughout experimental trials by conducting apilot study for local pressuremeasurements; and,evaluate the impact of thehydrodynamic on the fouling propensity ofthe membrane module by monitoring thedistribution of flow along the fiber. Both the CFD results and the environmental results are presented. Presentation conclusions indicate the following: CFD results - hydraulic path heterogeneitieswithin the connection box, pressure head-losses inside thefibers provide a pressure equilibrium; experimental results -good correlation betweenCFD/experimental measurements; and, impact on membrane performances - fouling in the upper part,clogging in the lower part but only2% of fibers concerned. Includes figures.
