建立了轴流中空纤维正向渗透(FO)组件的数学模型，并用NaC l-H2O体系的非稳态FO实验数据进行了验证。进料液(FS)和进料液(DS)浓度的最大偏差分别为0.7%和12%，实验结果与模型结果吻合良好。在不同的模块长度和操作条件下进行了模拟，分析了它们对渗透流量和功率消耗的影响。在仿真结果的基础上，建立了以组件长度、DS和FS压力、流量为决策变量的多目标优化模型，以获得FO流量和给水泵供电功率之间的最优Pareto。优化分析揭示了功率消耗与渗透流量之间的指数关系。最后，给出了用MOO最优Pareto优化FO对象性能的方法。
In this article, a mathematical model is developed for axial flow hollow fiber (HF) forward osmosis (FO) module and validated with unsteady-state FO experimental data of NaCl-H2O system. A maximum of 0.7 and 12% deviation in draw solution (DS) and feed solution (FS) concentration shows a good agreement between experimental results and model outputs. Simulations were carried out at various module length and operating conditions to analyze their effects on permeate flow rate and power consumption. Based on the simulation results, a multi-objective optimization (MOO) was formulated to get optimal Pareto between FO water flux and power supplied to the pump by considering the module length, DS and FS pressure and flow rate as decision variables. The optimization analysis revealed the exponential behavior of power consumption with respect to the permeate flow rate. Finally, a procedure to optimize the FO plant performance using MOO optimal Pareto is presented.
