Využití nanovlákenných struktur ve filtraci
Žákovič, Peter
In this diploma thesis, we focused on the filtration of wine, the type of filtration and the filtration methods currently used in the literary section. Further, filtration materials, which are used in wine filtration and, last but not least, the use of nanoparticles in viticulture and winemaking, have been described. In the practical part, commercial filter types were used, namely Cartridge filter C11 with nanofibrous filter membrane RIFTELEN N15-2 and RIFTELEN N15-5, which we compared with the Zambelli plate filter, in which we used filter plates HOBRAFILT S15N and HOBRAFILT S30N. In particular, we compared the content of free and total sulfur dioxide, wine turbidity, protein turbidity and polyphenols in wine. From each type of unfiltered and filtered wine, we put the samples in bottles of 750 ml and left overnight in the cellar. The next day we analytically measured each variant sample. All results were then statistically processed and evaluated with recommendations for practice and further investigation.
