Introduces the basic principles of quartz crystal mierobalance with dissipation （QCM-D） and its advantages,reviews the application of QCM-D on membrane fouling studies which including the effects of different membrane material and fouling types on membrane fouling and cleaning. The application of QCM-D has realized the quantitative analysis and online monitoring the membrane fouling, which has provided the evidence for further studying the mechanisms for membrane fouling and fouling removal. In coming research, the QCM-D can be further applied to inspect the mechanisms for membrane adsorption and cleaning, study the theory which prevents fouling, find out the rational and scalable ways to accomplish the membrane cleaning, and improve the cleaning efficiency.
