Abstract: Various transport models have been developed to describe the transport phenomena through reverse osmosis membrane. Such models give relationship amongst the operating variables, such as rejection, flux and driving force and membrane parameters that may include the physical properties of membrane. Knowing membrane parameters, one can predict the performance of membrane with minimum number of experiments, and can be extended to whole range of operating parameters without performing experiments. The available models are based on two concepts. One is on the basis of irreversible thermodynamics, and the others on the transport mechanisms. At present, the membrane transport models are used with the experimental data to estimate the parameters involved assuming that the mass transfer coefficient is available in the literature. The disadvantages of the same were reported recently in the literature. In the present paper an attempt has been made to evaluate the various models available in combination with the film theory .The experimental data obtained on the membrane is used to estimate the membrane parameters and mass transfer coefficient simultaneously, which will have more relevance than the existing methods. With this combined method, the models are compared.
