The classical solution-diffusion model,combined with the film theory,was then successfully applied to predict the performance of other three modules of larger size (suchasthe2.5″40″ and 4.0″40″ module sizes)
and/or made of a different membrane material (suchasLab-1). Inconclusion, the procedure proposed in this paper predicts the performance of a specific module by obtaining a limited number of experimental data for flat sheets and a1.8″12″ spiral-wound membrane module only (necessary to obtain the fitting parameters characteristic of the membrane and the module). Furthermore,with this procedure,it is not necessary to know a priori the spacer geometry,because the necessary information about the spacer geometry will be also obtained by regression of few experimental data.
