| Abstract: | Membrane technology has been widely used in the food industries because of its excellent separation ability. But the fouling of membranes made the capability of infiltration flux and quotiety of the remanet changed, shortened the operation life. These greatly limited the membrane technology applications in food industries.In this article, the mechanism of membrane fouling and the influence factors of membrane fouling were introduced. The preventative measures and the cleaning methods of the recent research were also discussed in this paper. |
