Analysis of water age in the water supply network of a selected area
Pellarová, Tereza ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor thesis deals with the issue of water age in drinking water distribution system. The theoretical part discusses the factors influencing the age of water and the quality of delivered water, and also the way in which the age influences the quality of water. Furthermore, the methods of age determination are mentioned, as well as indicators of high age. The consumption of mains water and water prices in Europe are also discussed. The practical part of the thesis focuses on the analysis of the age of water in the water supply system. The data needed for the analysis was obtained by means of the EPANET 2.2 tool, in which simulations were performed for periods with different water consumption, including the annual average, summer (July, August) and winter (January, February). After the simulation, the data were entered into MS Excel and then statistically processed and evaluated. The aim of the practical part was to find the correlations of the factors acting in the network. The age/velocity and age/flow rate were examined in the water main sections. The relations between age/consumption from the nodes and age/pressure were examined in the nodes of the network. All data were monitored within the constant age intervals occurring in the municipality´s shared water supply system.

Removal of metabolites of pesticides from groundwater during treatment for drinking water
Vaněk, Michal ; Repková, Martina (referee) ; Král,, Pavel (advisor)
The diploma thesis deals with the evaluation of the efficiency of pesticide metabolite removal at a water treatment plant. In the introduction, a research on the issue of pesticide substances in raw water, their removal during the treatment to drinking water and the basic classification of pesticides is made. The thesis includes an introduction to the issues at a specific water treatment plant, technological changes at the water treatment plant, tabulated and graphically processed measured values of pesticide metabolites in groundwater source and drinking water. In the conclusion of the thesis, individual pesticide metabolites are discussed, their sorption on granular activated carbon is assessed and conclusions are drawn.

Evaluation of the impact of technical and technological adjustments to the water treatment plant on the quality of treated water
Jedličková, Ivana ; Látal,, Milan (referee) ; Kučera, Tomáš (advisor)
The subject of this bachelor thesis is the evaluation of sequential technical and technological changes of water collection and modification at a specific water treatment facility – the water treatment facility in Ivančice. The first part of the thesis explains the basic terminology such as technological processes of the water treatment plant, types of water treatment facilities, the range of different types of water based on its quality and technologies that can be found at the water treatment plant in Ivančice. The next two chapters describe the water treatment process before and after intensification. The primary focus is on raw water collection, the quality of both raw and treated water, and the water treatment technology. The last part of the paper offers multiple comparisons of the original and renovated facility and recommendations for improving the operations of the renovated water treatment facility. The final evaluation was carried out based on the information collected mainly by visiting the facility in person, and other sources.

This thesis solves sanitary equipment installation and design of distribution of gray water in the hotel. Designed building has three floors and basement. On the first floor there are a restaurant, bar, conservatory, sanitary facilities and kitchen facilities. In the second and third floor are rooms for guests. In the basement there are storages, laundry room, engine room and other rooms, which are important for operation. The theoretical part is focused on familiarization with the theme of gray water, their division and possibilities. The practical part of applied knowledge on the subject at. The work also includes the calculation of return on this technological system.

MONITORING OF URANIUM IN DRINKING WATER IN THE SOUTH MORAVIAN REGION AND ITS ANALYSIS.
Hanusková, Vendula ; Doležalová Weissmannová, Helena (referee) ; Ing.Dita Janečková, (advisor)
The determination of uranium in samples of the enviroment was considered for liquadeted chemical toxicity of uranium and it is impossible to leave out a potential occurrence in drinking water. The purpose of this diploma thesis was the monitoring of preselected public water supplies in the South Moravia and post action analysis of those samples. That was all on the basis of the requierement of the Regional Hygiene Station. For determination of trace concentrations of uranium in drinking waters the method ICP-MS (Inductively Coupled Plasma with Mass Spectrometry) was chosen. All of the results were then summarized and evaluated. At the end are proposed feasible solutions and precautions for public water supplies operators.

Application of membrane technologies for the production of drinking water from the effluent from the WWTP
Minich, Marek ; Mergl, Václav (referee) ; Repková, Martina (advisor)
The Master’s Thesis deals with the application of membrane technologies in the production of drinking water from the effluent of a municipal wastewater treatment plant (WWTP). There were two types of pressure-driven membrane processes selected – ultrafiltration and reverse osmosis, to achieve water production of the required quality. For the needs of the diploma thesis, an already existing pilot-scale membrane unit of the ASIO TECH Company l.t.d. was used. There were 44 physical, chemical and microbiological parameters observed to assess the quality of the produced water and also the input water (effluent from the WWTP). None of the afore mentioned parameters exceeded the limit values, more specifically the highest limit values issued by the Decree 70/2018 Coll. However, the produced water cannot be considered as drinking water because of its low mineralisation. Before its potential application in practise, it is therefore necessary to choose an appropriate method of remineralisation as well as to follow all the other legislative requirements for the drinking water, which have already been out of the scope within the Master’s Thesis.

Criteria for drinking water for breeding medical leeches
Krýslová, Jana ; Řezáčová, Veronika (referee) ; Komendová, Renata (advisor)
This bachelor thesis deals with the issue of breeding leeches with regard to the quality of the water in which it is bred. It focuses on the comparison of individual criteria of drinking water taken from different sources of drinking water (Letovice, Brno and the surroundings of Brno). The sources of these waters are from Vír and Březová, or they are mixed in a certain ratio. Selected indicators of drinking water quality were measured in individual water samples using UV-VIS spectrometry, flame photometry, turbidimetry and volumetric methods. Rajec baby water, purchased from the retail network, was selected as a comparative sample. From the obtained data it was found that the values of water hardness have the greatest influence on the success of leech breeding. It is generally known that too hard water does not benefit the leech, and therefore it dies. For the other determined parameters, it was not possible to prove whether they have a significant influence on the breeding of leeches and its death.

Determination of pharmaceuticals in drinking waters using HPLC
Králová, Radka ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
The aim of the diploma thesis is the determination of macrolide antibiotics in drinking water by using of high performance liquid chromatography. Erythromycin and clarithromycin were selected such as representative macrolides due to frequently prescribed pharmaceuticals in this time. Solid phase extraction (SPE) by using of Oasis HLB cartridges was applied for pre concentration and purification of chosen analytes in real samples of drinking water. Optimalization of method and analysis were performed by using of high performance liquid chromatography with mass spectrometry detection (HPLC-MS). The suitable method was selected for determination of macrolides in real samples taken from two sources of drinking water, the interception of water in Litovel and Černovír Olomouc.
