Disposal of high saline brines is a common and important problem in many industrial plants. These waste streams may be generated in large volumes in many different industries. It is well known that these concentrated brines cannot be desalted by using the conventional desalination technologies due to two crucial factors which are; cost and reliability. Moreover, these factors have limited the scope of choice of other desalination processes for such applications. Hence this paper is aimed at providing an ideal disposal method that is economically and technically capable of producing energy by mixing and then disposing of high saline brines into a large body of water, with least harm to the environment. In this paper, various concepts in the utilisation of salinity gradient power are discussed to highlight what kind of methods are being proposed around the world for the energy exploitation, and also several novel ideas were addressed in this study to present the possibilities of implementing the osmotic pow...
