Dessalement
La technologie de dessalement transforme l'eau de mer en eau douce pour pallier la pénurie d'eau mondiale.

Le dessalement est la discipline industrielle et d'ingénierie qui consiste à éliminer les sels et les minéraux dissous dans l'eau de mer ou les eaux souterraines saumâtres pour produire de l'eau douce potable ou d'irrigation. Il approvisionne aujourd'hui plus de 100 millions de personnes dans des régions souffrant de stress hydrique au Moyen-Orient, en Afrique du Nord, sur les côtes asiatiques et, de plus en plus, en Europe du Sud et en Amérique.

Reverse osmosis (RO) dominates current installed capacity, pushing saline feedwater at high pressure across thin-film composite polyamide membranes whose selectivity, fouling resistance, and boron rejection rates remain active material science research fronts; thermal processes — multi-stage flash distillation and multi-effect distillation — retain relevance where waste heat from power generation is available as a cost-free energy input. The field’s central engineering constraint is specific energy consumption: state-of-the-art RO plants with pressure exchanger-based energy recovery now approach the thermodynamique Pour le dessalement de l'eau de mer, les exigences minimales orientent la différenciation concurrentielle vers la longévité des membranes, la conception des prises d'eau et la gestion du concentré de saumure, en tenant compte de la toxicité des rejets et des conditions marines. écosystème L'impact attire un contrôle réglementaire de plus en plus strict.

Emerging process architectures — forward osmose, membrane distillation, capacitive deionization, and graphene oxide or aquaporin-based membranes — target niche feedwater chemistries or off-grid renewable-powered configurations where conventional RO economics break down.

Les publications et les brevets répertoriés ci-dessous couvrent l'ensemble de ce spectre, depuis la synthèse des membranes et l'ingénierie des modules jusqu'à la thermodynamique des systèmes, la valorisation de la saumure, le couplage des énergies renouvelables et les évaluations hydrogéologiques des sites qui déterminent la viabilité des installations :
