Particle Deposition in Membrane Processes

膜过滤是对亚微米和微米(大约百万分之一米)范围内的颗粒和材料进行分离的主要技术。广泛使用这项技术的主要问题之一是由于颗粒的沉积而造成膜表面的污染(从而膜的有效性下降)。这是一个复杂的现象，需要合理地了解颗粒是如何从散体带到表面的，表面的蛋糕是如何形成和压实的，以及这些如何影响性能。本研究旨在对污垢进行全面的(实验和理论)研究。

Membrane filtration is a major separation technology for particles and materials in the submicron- and micron- size range (roughly one- millionth of a meter). One of the major problems in the widespread use of this technology has been the fouling of membrane surface (and hence the decline in the effectiveness of the membrane) due to the deposition of the particles. This is a complex phenomenon and requires a reasonable understanding of how the particles are carried from the bulk to the surface, how a cake at the surface forms and compacts, and how these affect performance. This research aims at a comprehensive (experimental and theoretical) study of fouling.
