20.500.12556/RUL-186027 Eksperimentalna analiza vpliva kavitacije na delovanje membranske destilacije Experimental analysis of cavitation on membrane distillation performance Pitna voda je ključna za obstoj človeka in ostalih življenjskih oblik. Zaradi veliko dejavnikov, med drugimi tudi antropogenih, postajajo njeni viri vse bolj obremenjeni in izčrpani, v mnogih delih sveta pa se zaradi tega že dolgo čutijo posledice, ki otežujejo človeške življenjske pogoje. Ena izmed rešitev za to problematiko je razsoljevanje morske vode, za to pa obstaja več tehnoloških procesov, med katere spada tudi membranska destilacija. Najpomembnejša komponenta procesa je membrana, ki je podvržena akumulaciji snovi na njeni površini. Proces zaradi tega pojava čedalje slabše deluje, v tem delu pa smo preverili ali je mogoče uporabiti kavitacijo za blaženje posledic akumulacije. Pokazali smo, da je to mogoče in da lahko izboljšamo delovanje procesa tudi pri čiščenju zelo slane vode, pri čemer je pomembna pravilna implementacija kavitacije v sistem. Raziskovalno delo je vsebovalo zasnovo in izdelavo laboratorijske merilne postaje, ki je omogočala izvajanje meritev pretoka destilata skozi membrano z in brez uporabe kavitacije. Posebna pozornost je bila namenjena izbiri primernega materiala na delu postaje, kjer je potekal odvod kondenzata. Drinking water is crucial for human existence and other lifeforms. Due to many factors, including anthropogenic, its sources are becoming increasingly strained and exhausted, with many parts of the world facing the consequences that are worsening human living conditions. Among the solutions for this problem is seawater desalination, for which many technological processes exist, one of which being membrane distillation. The most important part of the process is the membrane, which is prone to accumulation of materials on its surface. This hinders the process and the focus of this thesis was to check, whether it is possible to alleviate the effects of material accumulation with the use of cavitation. We proved it possible and that improving the process is feasible even when cleaning highly saline water, with the correct implementation of cavitation being crucial. The research included design and construction of a laboratory measurement station, which enabled measurements of distillate flux across the membrane with and without the use of cavitation. Special attention was devoted for the choosing of an appropriate material to be used in the condensate-draining part of the station. membranska destilacija kavitacija merilna postaja kondenzat membrane učinkovitost procesa membrane distillation cavitation measurement station condensate membranes process efficiency true false false [L.
