Abstract: This paper reviewed the module types：shear enhancing mechanism，permeability characteristics and economic evaluation of rotary shear-enhanced membrane ?ltration process (RSEMF). The advantages and drawbacks of the process were analyzed. It is recommended that the application of laser surveying instrument and computational fluid dynamics should be adopted for flow field observation and shear enhancing mechanism analyzing，and the critical flux and speci?c energy consumed per m3 of permeate are useful to analyze the permeability and evaluate the advantages of RESMF. To improve the performances of RESMF，more researches that are detailed should be conducted to investigate shear rate enhancement，module structure simplification，effective membrane surface increase， speci?c energy consumption decrease and the system cost. In addition， development of new modules，treatment of special solution with high concentration and the integration of RESMF and other types of membrane modules should also be considered as important factors.
