Abstract： |
| Based on the force analysis of micro-particles，the size optimization model of flat crossflow membrane module was established by combining the reverse idea of shallow tank sedimentation theory, and the size of flat membrane module was confirmed by using computational fluid dynamics (CFD) technology to simulate the micro-flow field. Humic acid (HA), sodium alginate (SA), and bovine serum albumin (BSA) were chosen as model foulants of effluent organic matter (EfOM) to investigate the antifouling performance of the membrane module experimentally. The results showed that when the ratio of length, width and height of the membrane module was 40:30:1, the flux decline rate of the optimized membrane module for HA, SA and BSA decreased by 14%, 9.3% and 7.9% respectively in two hours compared with the original module. The membrane fouling resistance was lower than that of the original module, indicating that the optimized membrane module using force analysis had a good effect on flow field and membrane fouling control. |
