摘要:
通过对陶瓷膜错流过滤微米级颗粒悬浮液过程中颗粒的受力分析, 获得了可沉积在膜表面颗粒的临界粒径, 结合传统的 滤饼阻力模型, 可获得膜表面污染层的阻力, 从而计算出过滤过程的渗透通量。与实验结果相比, 模型的模拟结果良好。
Abstract:
A simple model was established to predict the permeating flux of suspensions including micro -sized particles in the micro -filtration process using ceramic membranes .The model was developed by incorporating the fouling mechanism for various sizes of particles together with conventional cake filtration theories .The resistance of deposit layer depends on the critical size of particles which may deposit on membrane surface , which was calculated on the basis of the forces analysis of particles in cross -flow filtration .It was found that the model was capable of representing experimental results .
