A Review of Membrane Separation Process Enhanced by Shearing Force

Abstract

Due to the concentration polarization and membrane fouling, the application of conventional membrane separation technology is restricted. In order to reduce the concentration polarization and membrane fouling, the shear-enhanced process has become the focus of the current membrane technology. The shear-enhanced processes contain chiefly rotary tubular shear-enhanced process, rotary disc shear-enhanced process and vibratory shear-enhanced process. This article introduced the structures and work principles of the three shear-enhanced processes. Meanwhile, the problems and the prospect of the shear-enhanced process were provided in this article.
