Analysis of the Filtration Pressure in the Dynamic Filtration with a Rotating Cylinder Filter Media

通过对过滤装置内径向压力分布的分析 ,求出了过滤压差的计算式 ,清水透过实验表明 。

In rotary cylinder filtration, the filtration pressure was reduced accounting for the centrifugal pressure. The expression of the actual filtration pressure was given by the analysis of the pressure distribution in the radial direction. From the expression we could find that the filtration pressure was reduced, by improving the rotary speed, which was verified by the permeating experiment of pure water.
