Abstract

Nowadays, shortage of potable water for drinking, agriculture and industry is presenting a plausible threat to humans and life as a whole. More than 98% of the water present on earth is ocean water, which is highly saline. Desalination techniques that are in common practice are electro-dialysis, multi-stage flash distillation and reverse osmosis etc. and all they are well established and applied on an industrial scale. Separation processes have been continually developing in the last decade in which solvent extraction appears to contribute largely in these processes. Solvent extraction can is said to have started in the 1940s and developed rapidly and played an increasingly important rate in hydrometallurgy. One of the prominent features in the development of modern science and technology in the cross-fertilization of ideas among different disciplines, in which the contribution of solvent extraction with other techniques has generated a number of new separation processes, which include: solvent impregnated resins, electrostatic extraction, super critical extraction, extraction chromatography, reverse micelle extraction, gel extraction, membrane solvent extraction and finally liquid membranes. In this context, liquid membrane (LM) technology has lately emerged as a new prospective membrane separation technique, which has been applied only recently and effectively to the desalination of saline water. LMs offer numerous advantages over solid membranes, including more rapid mass transfer, absence of pores which can be blocked or fouled, and low energy consumption. To this end, the present study pertains to investigating the effect of different LM configurations on the efficiency of salt removal from saline feed donor phase (DP) to the receptor phase (RP) across the organic LM phase, immiscible in either of the two phases. Four configurations have been studied in the present work.
