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) dominiert die derzeit installierte Kapazität und fördert salzhaltiges Speisewasser mit hoher Geschwindigkeit. Druck Dünnschicht-Polyamid-Kompositmembranen, deren Selektivität, Foulingresistenz und Bor-Rückhalterate weiterhin Gegenstand aktueller materialwissenschaftlicher Forschung sind, spielen eine wichtige Rolle. Thermische Verfahren – mehrstufige Entspannungsverdampfung und Mehrfacheffektverdampfung – behalten ihre Relevanz, wenn Abwärme aus der Stromerzeugung als kostenlose Energiequelle zur Verfügung steht. Die zentrale technische Herausforderung in diesem Bereich ist der spezifische Energieverbrauch: Moderne Umkehrosmoseanlagen mit druckwärmetauscherbasierter Energierückgewinnung erreichen mittlerweile nahezu die angestrebte Effizienz. thermodynamisch Mindestanforderungen für die Meerwasserentsalzung, wobei sich die Wettbewerbsdifferenzierung auf die Langlebigkeit der Membranen, die Konstruktion der Einläufe und das Management des Solekonzentrats verlagert, wo die Toxizität der Abwässer und die Auswirkungen auf das marine Ökosystem von den Behörden immer strenger geprüft werden.
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:
