Concentrate treatments in reverse osmosis desalination plants: Status and innovative proposals

Abstract

The rise of the population growth with the pass of the years cause the rise of raw materials such as water. Because of supply this huge demand for fresh water, the desalination plants increase the brine flows discharged, which causes a greater environmental impact. This project aims to carry out a study of the management of brines from the rejection of desalination processes by reverse osmosis. A collection of different bibliographic sources and an investigation of the state of art in this field is carried out, delving into the most common aspects, such as the direct elimination of reject brines, the minimization of them and, finally, their reuse.

The range of the project encompasses the bibliographic search, the drafting of the most interesting and important points in it and, finally, a simulation in MATLAB of a system that reuse the exhaust gases of a microturbine to increase the salinity of a brine.
