ResumoA mathematical model of a reverse osmosis water purification system that can be used in process optimization studies is developed. A boundary layer flow model is used to relate water production rate to the operating pressure, Reynolds number, and membrane area. Cost equations that relate the capital and operating costs to the design variables are also developed. These relations are then used in economic analysis of several reverse osmosis systems. The results of computer simulation of single stage processes are presented. The model is believed to be accurate enough to describe the process and yet simple enough to be used in the simulation, design, and optimization of the process.
