Monitoring the effectiveness of the Hosov water treatment plant technology on the quality of drinking water
Gloc, Tomáš ; Látal,, Milan (referee) ; Biela, Renata (advisor)
This bachelor thesis deals with the monitoring of the effectiveness of the Hosov water treatment plant technology on the quality of drinking water, where an analysis of the received data was performed with a subsequent calculation of the efficiency for the technological line of the Hosov WTP in the periods of interest. The theoretical part is processed in the form of research regarding the necessary knowledge and context (resources, legislative limits, technological treatment processes) in contrast to water treatment. In the practical part, two periods of interest were chosen. The first comprehensive time period from the beginning of 2020 to the end of 2022 and the second time period, where the years 2012, 2019 and 2022 were chosen through a longer time interval. For the periods of interest, 6 indicators were monitored (color, turbidity, nitrites, CHSKMn, iron and manganese). Monitoring the concentration of indicators in raw water in selected periods enabled the assessment of changes in the quality of resources over the years. Concentrations of indicators in raw water and then in treated water were used to calculate and evaluate the overal efficiency of the technological line of Hosov WTP.

Microplastics in Drinking Water
Čermáková, Lenka ; Novotná, Kateřina ; Peer, Petra ; Janda, V. ; Pivokonský, Martin
The research was focused on microplastics occurring in water sources and in drinking water. Recently, the topic of microplastics in water is very up to date. However, most of the studies are focused on quantification of microplastics in sea water, sediments or surface waters, which are not a source of raw water for drinking water treatment, and at the same time the most of studies deal with the analysis of particles in the size range of 0.3 - 5 mm. The subject of the present study was to quantify microplastics from 0.2 μm in raw and treated water from three unnamed water treatment plants in the Czech Republic and to determine their size distribution, shape and material composition. It has been found that the number of microplastics ranged from 1414-7006 L-1 particles in raw water and 305-921 L-1 particles in treated water. Microplastics smaller than 10 μm were the most plentiful in both raw and treated water samples. Fragments clearly prevailed at two of the water treatment plants and fibres together with fragments predominated at one case.
