Abstract

Seawater desalination is an alternative that can extend water supplies beyond what is available in the hydrological cycle, with a constant and climate-independent supply. Radical transformation in the way we use natural resources is central to meeting the needs of future generations. The growing desalination market across the world has thrown up the challenges of management of Brine and EoL (End-of-Life) membranes. For achieving sustainable desalination strategy, the current economy based on linear model has to be replaced with circular economy model through suitable technologies. Here in our study, we have carried out various process studies for brine management and membrane management for facilitating the value addition to desalination plants and facilitating the reuse and recycle for lower end applications. The process technologies based on these studies are presented in this engineering article. The coupling of recovery of technology trace metals from brine using Radiation Induced Grafted sorbents is highlighted. These process studies and technologies will help to incorporate principles of the circular economy for the sustainable development of desalination.
