Uvajanje hidrodinamske kavitacije v postopek čiščenja komunalne odpadne vode

Gostiša, Jurij (author), Dular, Matevž (mentor), Hočevar, Marko (co-mentor)

Hidrodinamska kavitacija je zaradi mehanskih, termičnih in kemijskih učinkov označena kot metoda z visokim potencialom uporabe v procesu čiščenja odpadne vode. Kljub velikemu številu znanstvenih objav je tehnologija še v povojih, kar pripisujemo pomanjkanju načinov učinkovite generacije, ki je predmet doktorskega dela. V delu je zasnovan nov koncept rotacijskega generatorja hidrodinamske kavitacije s topimi kavitacijskimi elementi ter predstavljen razvoj na laboratorijski in pilotni ravni.

• Title: Incorporation of hydrodynamic cavitation into wastewater treatment

Abstract

Due to its mechanical, thermal, and chemical effects, hydrodynamic cavitation is characterized as a process with high potential for use in the wastewater treatment. Despite numerous scientific publications, the technology is still in its infancy, which we attribute to the lack of methods for efficient generation, which is the subject of a doctoral thesis. In the thesis, a new concept of a rotary generator of hydrodynamic cavitation with blunt cavitation elements is designed and the development at laboratory and pilot scale is presented.
