Proizvodnja plastike se iz leta v leto veča in s tem se veča tudi količina odvržene plastike. Le-ta botruje k nastanku mikroplastike. V nalogi smo identificirali koncentracije in vire mikroplastike, predstavili različne metode filtracije, analizirali membransko filtracijo in različne vrste membran ter identificirali trenutno najboljšo tehnologijo. Ugotovili smo, da je učinkovitost membran visoka, vendar odvisna od velikosti in oblike delcev mikroplastike. Potrebne so pogoste menjave membran, saj so le-te so podvržene mašenju in obrabi. Plastic production is increasing yearly and so is the amount of discarded plastic. This contributes to the formation of microplastics. In the final thesis, we identified concentrations and sources of microplastics, presented different filtration methods, analyzed membrane filtration and different types of membranes, and identified the current best technology. We found out that the membranes removal efficiency is high but depends on the size and shape of the microplastic particles. Frequent replacement of the membranes is necessary, since they are subject to fouling and abrasion. |
