The dataset describes theoretical data for the desalination of monovalent salt by reverse osmosis (RO) module. The two-dimensional mass transport model uses the solution friction theory to describe salt transport across the membrane. Model prediction was compared between the RO module computation with and without hydraulic pressure loss along the module length.<br>From a defined set of input parameters, the model output took the form of local salt concentrations (feed, membrane interface, and permeate), pressure (hydraulic and osmotic), cross-flow velocity, and fluxes (water and salt). We used a low salinity feed solution to compare brackish water membrane (BWM) and seawater membrane (SWM) module performance. A sensitivity analysis was also done on the membrane geometry and number of elements in a pressure vessel.<br>We use Maple V/Release 5 to perform numerical computations and transfer the data to an Excel sheet for plotting.

本数据集涵盖了采用反渗透（Reverse Osmosis, RO）组件脱除一价盐的理论模拟数据。该二维传质模型借助溶液摩擦理论描述盐分在膜两侧的传输过程。研究对比了沿组件长度方向存在水力损失与无水力损失两种情况下的反渗透组件模拟预测结果。
基于预设的一组输入参数，模型输出包含局部盐浓度（进料液、膜界面及渗透液）、压力（水力压力与渗透压）、错流流速以及通量（水通量与盐通量）。本研究采用低盐度进料液，对比了苦咸水膜（Brackish Water Membrane, BWM）与海水膜（Seawater Membrane, SWM）组件的运行性能。此外，还针对膜组件几何结构以及压力容器内的膜元件数量开展了敏感性分析。
本研究采用Maple V/Release 5软件完成数值计算，并将数据导出至Excel表格以用于绘图。
