Abstract：

A filtration mathematical model was successfully developed by complete mass balance and momentum balance to predict the local flux distribution along fiber. The effect of radial permeate flow on flow resistance was taken into consideration in the model. The effects of fiber length, inside diameter, average operating flux and membrane intrinsic resistance on local flux distribution were investigated using this model. The simulated results showed that there existed an effective working length of the submerged hollow fiber membrane at certain operating conditions. Furthermore, it was also found that the asymmetry of local flux distribution increased with the increase of average operating flux, fiber length and membrane intrinsic resistance, whereas it decreased with an increase in fiber inner diameter. This modeling plays a theoretical foundation for the optimizing and operating of hollow fiber membrane module.
