Using flotation in water treatment plants
Litschmann, Patrik ; Kučera, Tomáš (referee) ; Biela, Renata (advisor)
The bachelor thesis processes the principle of dissolved air flotation (DAF), its history, modifications and parameters. It also describes efficiency in removing cyanobacteria, algae and turbidity on surface sources. Additionally, the experience with flotation is described at the first separation stage in the Czech Republic and abroad. It has turned out that pre-project preparation, model tests and pilot tests are absolutely crucial for dissolved air flotation. Finally, flotation with sedimentation is compared in terms of flocculation, coagulation, sludge and their economic impacts.

Evaluation of the Technical State of Water Treatment Plants
Přecechtěl, Karel ; Slavíčková,, Kateřina (referee) ; Kučera, Tomáš (advisor)
The subject of this thesis is to create evaluation criteria of technical condition of water treatment plants. The thesis is divided into four parts. In the first part of this thesis are presented evaluation systems by performance indicators drinking water treatment plants, which are then applied in real time. There are detailed descriptions of individual performance indicators. Each evaluation conducted certain period of time. After the expiry of the period under review was to evaluate and create charts to display results. In the next chapter the thesis focuses on the identification data. First, it was necessary to find out all necessary information about the water treatment plant. Necessary information means information relating to building construction, human resources, mechanical parts, technological equipment and other entities with links to the operation of the water treatment plant. All these data were sorted for better overview and facilitate setting evaluation indicators. The third part of this thesis is focused on the development of indicators that are used to determine the current status of the water treatment plant. As a first step was established 19 indicators used to evaluate the condition of the entire water treatment plant. Followed by a description of the individual indicators and then determine the individual evaluation criteria. In the last part of this thesis was carried out by the proposed criteria on selected water treatment plants. They were selected three water treatment plants located in the Czech Republic, which held a personal tour of each water treatment plant. This was followed by an overall assessment of the technical condition of water treatment plants.

Technical and technological audit of the water treatment plant
Jedličková, Tereza ; Svoboda, Pavel (referee) ; Kučera, Tomáš (advisor)
The aim of the submitted diploma thesis is the implementation and evaluation of the technical and technological audit of water management systems of water treatment plants – concretely Plzeň Water Treatment Plants. Part of its audit is a description of potable water production, including the evaluation of the TEA Water treatment plant, evaluation of quality assurance of raw and produced drinking water, analysis of costs and pricing costing, personnel evaluation, care of the plant and draft measures for better working of the whole system. The work also focuses on the characteristics, history and the past reconstruction and more detailed description of the individual cleaning stages of the selected water treatment plant in Pilsen. The audit itself was preceded by the study of current legislation, namely the Law No. 274/2001 Coll. and Decree No. 428/2001 Coll. The diploma thesis also describes performing laboratory analyzes in an accredited laboratory of Plzeň Water Treatment Plants.

Water Treatment Plants Innovation Opportunities
Zelený, Zdeněk ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
This master´s thesis deals with the possibilities of innovation process water treatment. Specifically, to explore the use of sodium water glass and nanoiron in removing heavy metals from raw water at the drinking water treatment. For the comparison was used traditionally used coagulant, particularly liquid aluminum sulfate. The introductory part deals with the possibility of modifying the surface water during the treatment process such water into potable water. This chapter is a description of the quality of raw water used, then the description of currently used separation processes. Furthermore, they are described and commonly used types of treatment plants. Conclusion The introductory section deals with traditional coagulants and form a suspension. Another part of this master´s thesis has been devoted to the possibilities of innovation in the treatment of raw waters as drinking water, describes the options and features of the use of water glass and nanoiron. The following section describes the experimental part of this thesis. It is followed by the experimental results. The last chapter summarizes the acquired knowledge and commented on the measured values of the experimental part. This work also shows several specific projects using innovative technologies presented.

Use of membrane processes in water treatment
Spratková, Aneta ; Kučera, Tomáš (referee) ; Biela, Renata (advisor)
This bachelor thesis contains a description of the basic properties of membrane technologies. It deals with the membrane process used in the water treatment for drinking water, especially pressure driven and electrically driven membrane processes. Also included are specific examples of water treatment plants where these technologies are used. The examples are from the Czech Republic as well as worldwide.

Water Treatment Plants and their Failure Modes
Baranová, Zuzana ; Anderle, Lukáš (referee) ; Kučera, Tomáš (advisor)
The aim of this thesis was to conduct a survey in selected water treatment plants to identify possible faults with which treatment providers may encounter. Within the thesis has been visited these treatments: ÚV Troubky, ÚV Hosov, ÚV Příkazy, ÚV Černovír. Further was performed evaluation of the collected information, specification and frequency disturbances occurring on those premises.

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.

The impact assessment of water treatment plants on water quality in the recipient
Kunert, Michal ; Benešová, Libuše (advisor) ; Šťastná, Gabriela (referee)
Watercourses influenced by anthropogenic activity increases in recent years and streams lose their natural character. This situation is critical particularly in small streams with minimal flow rates. The present work deals with the assessment of streams affected by discharges of treated wastewater from small waste water treatment plants. The results showed that in case of average flow in the recipient none of the monitored waste water treatment plants do not negatively affect the stream. Problems can occur when snow melts, when the lower temperature of the flowing water in the wastewater treatment plants negatively affect biological cleaning processes.
