Water temperature in the water supply network
Veniger, Jan ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor thesis deals with the analysis of water temperature in the water supply network of the municipalities of Kanice and Řícmanice. These are municipalities located in the South Moravian Region, in the district of Brno-venkov. First, the available literature that was used in the data processing is described. For the purpose of temperature measurements, the Astacus technology used by Voda Brno, s.r.o. for controlled flushing of water pipes was used. Furthermore, the water temperature distribution along the length of the pipeline on individual parts of the water supply lines is described. In the last part of the paper the influence of the assessed factors on the water temperature is discussed.

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.

Use of Renewable Energy Sources for Water Recovery
Patera, Jan ; Vojtek, Martin (referee) ; Baxant, Petr (advisor)
The bachelor's thesis deals with a summary of the basic theory for obtaining water from air humidity and it‘s following treatment in order to meet the hygienic regulations of drinking water. It presents the basic principles usable for obtaining water from the air, also presents the basic principles, including a basic overview of existing equipment for obtaining water from the air. It defines ideal conditions for obtaining water using atmospheric water generators. In a specific locality is determined a proposal for the water yield with energy performance during the year. Furthermore, the work deals with the use of renewable resources in obtaining water and the possibility of its subsequent treatment.

Strategy of Entrance of Company on Foreign Market
Gebauerová, Jaroslava ; Plšek, Martin (referee) ; Zich, Robert (advisor)
This thesis deals with strategies for firms entering the foreign market. In the theoretical part of the work the various strategies and their pros and cons are discussed, together with the dynamics of entering a new market. The analytical part of the work comprises an analysis of the Austrian market and an internal analysis of the company AQUAL Ltd. selected for the practical application. Its SWOT analysis and description of its entrance to a foreign market according to the SMART method are performed. Proposals are given the gradual development of the strategy of entrance, including the reasons for choosing a mixed strategy, and aspects of the operation and management of the company abroad are described; important is the definition of activities of the manager for Austria. Finally, conclusions are given summarizing the prerequisites and expected benefits of the entrance, the goals fulfilled and the contributions provided in this work.

Assessment of the effectiveness of filter material DMI-65 on removing metals from water
Konečný, Jiří ; Hrich, Karel (referee) ; Biela, Renata (advisor)
The first chapter of diploma thesis discusses about various water processes which remove metals and metalloids compounds from water. A substantial part is devoted to filter materials, which include a new filter material DMI-65. Comprehensive chapter discribes characteristics, proporties and practical application of filter material DMI-65. The next chapter describes the process of pilot testing of material DMI-65 in the water treatment plant in Ivancice. At the end of the diploma thesis, the laboratory test of filter material DMI-65 is described, including the description of particular metals that are removed from the water and the compresion of the filter materiál DMI-65 with other selected filter materials.

Improvement of Manganese Separation in Drinking Water Treatment
Bartoš, Ladislav ; Janda, Václav (referee) ; Hlaváč, Jaroslav (referee) ; Dolejš, Petr (advisor)
The submitted paper covers manganese comprehensively. The introduction provides an overview of its basic physical and chemical properties. Its compounds are discussed individually, including their preparation, production, and practical uses. Furthermore, a list of analytical methods in which manganese is involved in the form of its compounds as reagents is included. The same section includes an overview of analytical methods whereby manganese and its compounds are detected, primarily in water industry processes. Attention is paid to manganese as a non-negligible constituent of the various parts of the environment. The section on manganese’s biogenic properties is interesting from the viewpoint of its toxicity as well as its role as an important biogenic element, indispensable primarily for mammals. The subsequent chapters discuss the various methods which are suitable, under specific conditions, for separation in the treatment of surface and underground water aimed at producing drinking, process, or industrial water, where a minimal concentration of this metal is required. The impact of the physical/chemical conditions which influence the efficiency of separation in a manner ranging from non-negligible to principal, is discussed further on. Given the specifics of treatment of surface [and] underground water, the chapters provide more details on the processes suitable for specific types of matrix and specific conditions. Next chapters sum up many years of the author’s observations and experiences in the various parts of the water management system, from the raw water source to treatment to distribution, focusing on surface and underground water separately. Last chapter describes the construction of a water treatment plant model, its launch and calibration, and the tests focused on separating manganese by way of coagulation using aluminium and iron sulphate.

Properties of fine sediments in the water supply network
Dukát, Petr ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
This bachelor’s thesis deals with properties of fine sediments which occur naturally in water supply pipes. With focus on issues of fine sediments samples literature search was made and measurement methodology, which enables better understanding the behavior of sediment in the water supply network, was determined. During controlled pipes flushing, samples of fine sediments were taken from selected water pipes sections and under laboratory conditions sedimentation test, using measurement methodology, was made. Sedimentation test included the measurement of turbidity for the time necessary to meet the limit value of turibidity given by the government regulation for drinking water. Results of this thesis are important input information for simulating the spread of high turbid water in the water supply network during a turbidity event.

Quality of drink water in Moravian-Silesian region
Diblíková, Michaela ; Navrátilová, Jana (referee) ; Omelková, Jiřina (advisor)
The objective of this work was determination of quality of waters made and spent in Moravskoslezský region by methods using Morava a. s laboratory. At interval from 2005 to 2006 was provided by the statistic analysis of accoplishments, that the maximum of pollution is microbial origin firstly by bacteries of Enterobacteriaceae tribe (coliform bacteries a E. coli). Chemical pollution was mainly provided by amonia ionts and by nitrates. It can may be contamination effect of inside or surface flows by fertilizers or septic tank wastes infiltrative.
