Dilute single and mixed solute systems in a spiral wound reserve osmosis module Part I: Theoretical model development

A model of a spiral wound reverse osmosis module for dilute single and mixed solutes in water, which accounts for the material balances, effect of mixing on mass transfer, and pressure drop throughout the module, has been developed. The membrane mass transport model, applicable at any point in the module, can be chosen independently of the design equations. Two membrane mass transport models are considered: the Kimura-Sourirajan Analysis (KSA) …
