Dilute single and mixed solute systems in a spiral wound reverse osmosis module Part II. Experimental data and application of the model

In Part I of this paper a system design model for a spiral wound reverse osmosis module was developed. The model allows for the choice of membrane mass transport model and describes material balances, pressure drop, and mixing in the feed channel. In the current paper this model is used to analyze data for single and mixed solute experiments with dilute aqueous alcohol solutions. A commercial FilmTec FT-30 brackish water spiral wound membrane …
