流动结构对陶瓷管膜滤器过滤性能的影响

采用实验方法对内旋流式和十字流式陶瓷膜器作了水动力学研究。实验结果表明，内旋流陶瓷膜顺的过滤通量比传统的十字流工陶瓷管膜器的大得多，

Effect of Flow Fields within Tubular Ceramic Membrane Assembles on their Microfiltration Performance

The effects of different flow fields on filtration flux of tubular ceramic membrane assembles and the hydrodynamics in them are studied experimentally. It is shown from the experimental data that the filtration flux for assemble with inner swirling flow is much larger than that with traditional crossflow. Flow field of liquid would greatly influence the growth of filter cake on the membrane. Increasing the shear stress of liquid at membrane would enhance the filtration flux of assemble, with the treatment capability of the assemble increasing.
