    Development comes with various constraints, and among the most pressing of the 21st century is the availability of conventional freshwater, driven by climate change and de mographic growth. In arid and semi-arid regions such as north Africa, the water crisis is imminent as projections show rainfall is expected to drop significantly by 2050. To cushion the impact and decrease regional vulnerability, desalination has emerged as a non-conventional alternative. Reverse Osmosis (RO) is the world’s lead desalination technology, it surpasses its con testant demineralization technologies [1] being the most energy efficient process. This dissertation is a case study of the UTE Desaladora plant located in Skikda, Algeria, producing 100 000 cubic meters a day through the RO process. Seawater Desalination (SWD) appears to be a necessity given the urgency of the matter, but also a challenge, the interdependency between water and energy, often referred to as water-energy nexus is the central concern of this work. In this context, we have conducted a comprehensive, multi-scenario craddle-to-gate Life Cycle Assessment (LCA) with a focus on three main impacts : Climate change : Global Warming Potential, Marine eco-toxicity, Fossil Fuel depletion

    Simplified CFD-Based Performance Evaluation of Reverse Osmosis Membrane for Seawater Desalination
    (National Higher School of Technology and Engineering-Annaba, 2025) FAROUKI Boutheina; KHERBECHE Selma; CHENITI Hamza (Encadrant)
    This work presented a preliminary CFD simulation of a simplified RO model, both the geometry and physical properties were intentionally simplified to reduce the meshing complexity thus computational coast , nonetheless the minimal 2d model still captured the essential phenomena relevant to our objectives which is a better understanding of the mechanical fluid behaviors within the membrane. The focus was shifted to investigate key dynamics including: velocity field, pressure drop, and solute concentration distribution .The simulation results revealed consistent patterns in velocity distribution and pressure trends, but lacked precision and didn’t capture the polarization of solute concentration ,rather capturing a homogeneous constant flow. In summary,this CFD study is a useful starting point and provides a solid foundation for further advanced and realistic RO simulations
