Bei der Entsalzung handelt es sich um die industrielle und ingenieurtechnische Disziplin der Entfernung gelöster Salze und Mineralien aus Meerwasser oder brackigem Grundwasser zur Gewinnung von Trinkwasser oder Süßwasser in Bewässerungsqualität. Mittlerweile werden über 100 Millionen Menschen in wasserarmen Regionen im Nahen Osten, Nordafrika, Küstenasien und zunehmend auch in Südeuropa und Amerika mit Wasser versorgt.
Umgekehrt Osmose (RO) dominates current installed capacity, pushing saline feedwater at high Druck 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 thermodynamisch minimum for seawater desalination, shifting competitive differentiation toward membrane longevity, intake design, and brine concentrate management, where discharge toxicity and marine Ökosystem impact attract tightening regulatory scrutiny.
Neue Prozessarchitekturen - Vorwärtsosmose, Membrandestillation, kapazitive Deionisierung und Graphen Oxid- oder Aquaporin-basierte Membranen - zielen auf Nischenspeisewasserchemie oder netzferne, mit erneuerbaren Energien betriebene Konfigurationen ab, bei denen die Wirtschaftlichkeit konventioneller Umkehrosmoseanlagen versagt.
Die unten aufgeführten Veröffentlichungen und Patente decken das gesamte Spektrum ab, von der Membransynthese und Modulentwicklung über die Systemthermodynamik, die Soleverwertung, die Kopplung erneuerbarer Energien bis hin zu den hydrogeologischen Standortbewertungen, die die Rentabilität von Anlagen bestimmen:
