Abstract

Mikroplastični delci so globalni problem, katerega smo se začeli zavedati šele v zadnjem času, zaradi njihove majhnosti, nepravilnih oblik, ter različnih materialnih lastnosti je njihova detekcija zelo problematična in predstavlja svojevrsten izziv. To magistrsko delo v prvem koraku zajema pregled do sedaj uporabljenih tehnologij za detekcijo mikroplastike. V nadaljevanju pa opisuje zasnovo in konstruiranje optičnega merilnega sistema, ki omogoča merjenje delcev mikroplastike v toku vode. Ves postopek je razdeljen na faze, ki zajemajo razčlenitev problema, snovanje idejne zasnove, izdelavo konceptov rešitev in njihovega vrednotenja, izbiro najboljšega koncepta/rešitve, 3-D modeliranje, izbira najprimernejše tehnologije za izdelavo in v zadnji fazi izdelavo merilnega sistema. Izvedena je bila meritev na predpripravljenih vzorcih, ki smo jih po velikosti razdelili na tri podskupine. V zaključku je bila izvedena evaluacija rezultatov ter primerjava med klasično metodo merjenja pod mikroskopom in zasnovanim optičnim sistemom.

Secondary title:	Measurement of microplastic particles size in water flow
Secondary abstract:	Microplastic particles have become a global problem, but their small size, irregular shapes, and varying material properties make detection extremely difficult. In this master's thesis, the author presents an overview of technologies currently used for microplastic detection. The thesis then outlines the design and construction of an optical measuring system capable of detecting microplastics in water flow. The process is divided into several phases, including problem analysis, conceptual design, solution concept creation and evaluation, selection of the best concept/solution, 3-D modeling, selection of suitable manufacturing technology, and measuring system production. To test the system, pre-prepared samples were used, divided into three subgroups based on size. Results were evaluated and compared to the classic method of measuring under a microscope. This work represents an important step towards improved detection and monitoring of microplastics, addressing a crucial environmental issue.
