Compaction and fouling can now be characterized in-situ, in real-time using a noninvasive and completely nondestructive ultrasonic technique. Results indicate that the ultrasonic measurements are sensitive to the flow conditions in the separation cell and the fouling morphology on the membrane surface. Changes in the values of the ultrasonic parameters occur on the same time scale as the permeate rate-change data. There is no accepted theory that accounts for the morphology of the fouling layer developed during desalination. This study provides an important tool whereby the real-time information obtained will enable new models and theory for fouling to be developed.
