Although water is essential for human survival and has always been critical to the social and economic growth of the world, it is unfortunately distributed irregularly worldwide and is threatened by countless source of pollution. Addressing the issue of water resources sustainability is extremely crucial for societies in order to maintain safety as well as social, ecological and economic progress. The issue of water scarcity has pushed the world to develop adequate technologies and approaches for sustainable water resources management. In addition, to seawater and brackish water, industrial and municipal wastewater are also considered to be important available resources that need to be taken into consideration to increase sustainability and at the same time to meet SDGs. Indeed, as the population grows, agricultural, domestic and industrial activities produce large amounts of wastewaters that can be treated and reused in variety of purposes considering circular economy philosophy. Nowadays, wastewaters are treated in order to be reused for industrial, agricultural and other domestic purposes. In this context, membrane technology is a preferred choice for treatment of water from different wastewater streams for reuse in a more sustainable way, taking into account the philosophy of circular economy and the targets set from UN. This review discusses the links between the concept of sustainability and the treatment of water resources, including wastewaters with membrane technology. It provides a tangible framework for presenting the relevant challenges and future prospects but also the benefits that will come. The practical results of the research serve as reference point for stakeholders, policy makers dealing with sustainable water development strategies considering SDGs and circular economy.
