AB  - This paper introduces solute-solvent interactions onto a universal transport modeling approach that has been recently introduced for predicting RO membrane performance. The mathematical modeling framework utilizes chemical potential calculations rather than concentrations, and is based on the standard solution diffusion theory. Accounting for solute-solvent interactions were all based on a Maxwell-Stefan approach for reduced motion of particles in membrane pores. Overall, the proposed model is very effective in generating all the necessary parameters, especially for estimating the water permeability, as well as the various permeabilities associated with both, monovalent and divalent types of ion in the solution. Moreover, the effects of osmotic pressure on the respective species and water flux can be estimated. The proposed RO model was found to be very efficient in predicting the performance of various types of membranes, and its performance has been validated against available membrane performance data obtained from various sources. Since the attained model predictions are in very good agreement with actual membrane performance data, the proposed model can be considered as a very effective tool for use in commercial process simulator platforms.

AB  - U cilju proučavanja termodinamičkih svojstava binarne smeše limonen + hloroform eksperimentalno su određene gustine (ρ), viskoznosti (η) i indeksi refrakcije (nD) za ovu smešu. Eksperimentalna merenja su rađena u opsegu temperatura od 288,15 do 323,15 K na atmosferskom pritisku, za ceo opseg udela. Na osnovu eksperimentalno dobijenih rezultata izračunate su vrednosti 
dopunske molarne zapremine VE, vrednosti promene viskoznosti ∆η i vrednosti promene indeksa refrakcije ∆nD. Za izvedene vrednosti rezultati su dobijeni fitovanjem Redlich-Kister polinomskom jednačinom. Na osnovu ovih rezultata izvedeni su zaključci o međumolekulskim interakcijama u limonen + hloroform binarnom sistemu. Vrednosti dopunske molarne zapremine, kao i vrednosti promene viskoznosti i indeksa refrakcije pokazuju pozitivno odstupanje u celom opsegu molskih udela. Povećanje dopunske molarne zapremine pokazuje da je pakovanje molekula u smeši manje efikasno nego u čistim komponentama.
AB  - In order to study the thermodynamic properties of the binary mixture limonene + chloroform, the densities (ρ), viscosities (η) and refractive indices (nD) for this mixture were experimentally determined. Experimental measurements were performed in the temperature range from 288.15 K to 323.15 K at atmospheric pressure, for the entire range of composition. Based on the experimental results, the values of excess molar volume VE, the viscosity deviation ∆η and the refractive index deviation ∆nD were calculated. Additionally, the excess molar volume and viscosity and refractive indecies deviations were fitted with the Redlich-Kister polynomial equation. Based on these results, conclusions can be made on intermolecular interactions in the limonene + chloroform 
binary system. Values of excess molar volume, viscosity and refractive index deviations have shown a postive non-ideal behavior in the entire composition range. An increase in the values of exces molar volume indicates that the packaging of the molecules in the mixture is less efficient than in the pure components.
