A detailed model of spiral wound reverse osmosis membrane modules is developed. Cross-sectional spiral curves are reconstructed as a function of a winding angle. Asymmetric spatial variations in a folded membrane are observed. The proposed model is validated against experimental data. Geometric features are shown to have a great impact on overall process performance.
