    Abstract: For supplying drinking water throughout the world, there has been a huge growth in the usage of desalination factories. Nevertheless, the formation of brine (concentrate) is a complete side of the working of the desalination factory and encounters serious ecological defiance due to its elevated salinity. Thus, a cost-effective and environmentally f... Show More
