Abstract
In this paper, a one-dimensional mathematical model based on coupled differential and algebraic equations
has been developed for analysing the separation mechanism of a N-nitrosamine in a spiral-wound reverse
osmosis process. The model is based on Spiegler and Kedem’s work on mass transport and Darcy’s law and
concentration polarization to analyse the pressure drop and mass transfer coefficient in the module feed
channel respectively. The model is built using the gPROMS software suite and validated using N-nitrosamine
rejection experimental data from the literature, obtained by using a pilot-scale cross-flow reverse osmosis
filtration system. Analysis results derived from the model corroborate experimental data.
