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.本数据集收录了采用反渗透（RO）模块对一价盐进行脱盐处理的理论数据。该二维传质模型采用溶液摩擦理论描述盐分的跨膜传输过程，并针对沿模块长度方向存在水力压降与无水力压降两种工况下的反渗透模块计算结果，开展了模型预测值的对比分析。 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（BWM）与海水膜（SWM）模块的运行性能，并针对膜组件几何参数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完成数值计算，并将数据导出至Excel工作表中以用于绘图。
