In this study, modeling and simulation of removing a common pharmaceutical contaminant by a hollow fiber membrane contactor (HFMC) were carried out. For this purpose, a model was presented for separation of ibuprofen from wastewater in the membrane contactor. The suggested model was developed by coupling the mass and momentum equations. The partial differential equations (PDEs) and the corresponding boundary conditions of the model were solved using the computational fluid dynamics (CFD) techniques. The results showed that the predictions of this model were in close agreement with experimental data obtained from the literature. Moreover, the effects of different design and operating parameters on the removal of ibuprofen were studied. The simulation results revealed that the removal of ibuprofen was increased by increasing the membrane porosity and the length of fibers. The ibuprofen removal efficiency was also enhanced up to 93.2 and 90.2% by increasing the inner radius and the number of fibers from 110 to 145 μm and 3,000 to 15,000, respectively. As a result, this study illustrates the successful development of the CFD model for prediction of ibuprofen removal using HFMC according to which removal efficiency of more than 95% was achieved.

使用中空纤维膜接触器去除布洛芬的计算流体动力学建模

在这项研究中，进行了通过中空纤维膜接触器（HFMC）去除常见药物污染物的建模和仿真。为此，提出了一种在膜接触器中从废水中分离布洛芬的模型。通过耦合质量和动量方程来开发建议的模型。使用计算流体动力学（CFD）技术求解了偏微分方程（PDE）和模型的相应边界条件。结果表明，该模型的预测结果与从文献中获得的实验数据非常吻合。此外，研究了不同设计和操作参数对布洛芬去除的影响。模拟结果表明，布洛芬的去除通过增加膜的孔隙率和纤维长度而增加。通过将内径和纤维数量从110增加到145，布洛芬的去除效率也提高到93.2％和90.2％微米和3,000至15,000。结果，该研究说明了成功开发出使用HFMC预测布洛芬清除率的CFD模型，据此，清除率达到了95％以上。
