Čistírny odpadních vod v horských oblastech
Frank, Ivo ; Plotěný, Karel (oponent) ; Hlavínek, Petr (vedoucí práce)
Cieľom diplomovej práce je spracovať prehľad technológií používaných pri čistení odpadových vôd v horských oblastiach ako na Slovensku, tak aj v zahraničí. Súčasne diplomová práca mapuje spôsoby čistenia vôd používané na vybraných objektoch v oblasti Vysokých Tatier. Na objektoch s nevhodnou technológiou bude navrhnuté vhodnejšie riešenie spomedzi skúmaných technológií.

Elimination of nanoplastics by cavitation and advanced oxidation processes
Kluknavská, Júlia ; Burda, Radim (oponent) ; Rudolf, Pavel (vedoucí práce)
The Present Thesis deals with nano and microplastics pollution of the environment and with possible elimination thereof. The thesis includes a research and an experimental part. The research describes the issues of micro and nanoplastics in terms of their formation, dispersion into the environment and into the living organisms. The research part concludes with description of current solutions of micro and nanoplastics elimination from the wastewater. The current wastewater treatment solutions are in particular based on filtration method which by definition may not be absolute. There was an assumption pronounced that using CaviPlasma device may render elimination of micro and nanoplastic from wastewater. The aim of the thesis was to experimentally verify that assumption. Test sample used was the suspension of water and polyamide particles which was subsequently exposed to the cavitation and plasma discharge. The experiment did not result in elimination of particles, nor visible disruption thereof. However, it was shown that plasma discharge may initiate the agglomeration of the particles to such an extent that continuous structures of microplastics are observed. This phenomenon may potentially be beneficial for microplastics filtration.
