AB The global challenges of water pollution and scarcity due to industrial demands and population growth, have generated alarming concern. The sixth sustainable development goal of the 2030 agenda highlights the need for availability and sustainable management of water and sanitation. To address these critical concerns, efficient water resource management is essential, and wastewater treatment plants (WWTPs) play a critical role. Municipal WWTPs are designed not only to mitigate pollution but also to protect environmental quality and human health and to take advantage of valuable resources such as water, nutrients and energy. As urban populations increase, WWTPs must adapt to changing environmental constraints and transition toward more sustainable and resilient treatment systems that prioritize low environmental impact and energy efficiency.Conventional wastewater treatment encompasses various physical, chemical and biological processes to remove solids, organic matter and occasionally nutrients from wastewater. While effective on conventional contaminants, it struggles removing emerging contaminants such as pharmaceuticals and hormones. Consequently, great efforts have been directed to the development of advanced wastewater treatment  technologies, such as membrane filtration, adsorption and advanced oxidation processes, to improve the removal efficiency of contaminants and nutrients. Membrane technology, in particular, has emerged as a preferred manner of recovering water from various wastewater streams, which holds promise for resource recovery and environmental sustainability.In this context, this thesis delves into the utilization of Forward Osmosis (FO) technology for the treatment of municipal wastewater. This technology makes possible to use the osmotic pressure of a salt solution as the driving force, instead of a mechanical pressure gradient as would be done in a Reverse Osmosis (RO) process. This results in considerable energy savings in favor of RO. Our study investigates the performance of different FO membranes and focuses on the remotion of emerging contaminants from wastewater, shedding light on the potential and challenges of this innovative technology.
