Optimal simulation of submerged hollow membrane fiber module

The optimization of hollow fiber membrane configuration is play a key role in controlling membrane fouling.The non-uniform distributed local flux on hollow fiber promote the fiber fouling development,so the axial flux distributed index Df is the objective function in this study.Base on the model of filtration through a hollow-fiber membrane,two-end permeate produced fiber configuration was optimized.The numerical simulation results indicated that lumen diameter and length influenced Df significantly.According to the experience of a commercial hollow fiber in practice,when Df was controlled 1%～3%,the fiber lumen diameter change from 0.6 to 0.8 mm,the fiber length of 0.66～2.06 m is the optimum range.
