Abstract

The models for the description of the performance of the reverse osmosis process for the behaviour of the boiler feed water were presented. The models developed were to predict the feed solution concentration and transmembrane pressure during the treatment process as the separation would involve the diffusion of solvent from the solution with more solvent to the solution with low solvent. The diffusion takes place as the impurities in the boiler feed water are diffused through the membrane employed in reverse osmosis process for treatment of boiler feed water. The operational parameters were obtained from the plant and serve as input data for the computer program developed using MatLab software. The model results showed agreement with previous studies with minimum deviation. The simulations showed optimum separation when the transmembrane pressure was about 180Pa with the reverse osmosis process adjusted to real rejection fraction of 0.4%. Also, the impurities as at this transmembrane pressure of 180Pa had been diffused completely to clean and clear solution through the membrane. Hence, total flux been adjusted in the reverse osmosis process for boiler feed water treatment at optimum of 178Pa would be the transmembrane pressure. This means that total flux is a better sensitive parameter to be used in the purification of boiler feed water for the diffusion of impurities from the boiler feed water since the transmembrane pressure was lower when total flux was used as adjustable variable.
