Progressive methods for waste water treatment
Doležalová, Adéla ; Konečná, Eva (referee) ; Vondra, Marek (advisor)
This bachelor thesis contains a description of progressive separation methods for wastewater treatment. It deals with the basic principles of separation methods, including membrane processes, sonolysis, ozonization, photolysis and photocoalysis. Their strengths and weaknesses are also described. Part of the thesis is also evaluation and comparison of individual technologies with regard to their practical applicability.

Additional Treatment of Drinking Water at the Point of Consumption
Hrubý, Ladislav ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
This bachelor’s thesis deals with problem of pollution in drinking water during its transport towards consumers. It particularly deals issues with heavy metals such as lead, copper and sums up methods which can be used when trying to remove such metals at water connections or taps. Next, particular filter materials are described together with processes that happen during filtration. Finally, a short experiment has been performed for finding out the most appropriate filter material.

Water Treatment Plants in the Czech Republic
Pavlů, Tomáš ; Vašalovská, Petra (referee) ; Kučera, Tomáš (advisor)
The thesis is aimed on establishing of well arranged catalogue of selected water treatment plants in the Czech Republic, with special regard to basic information about particular plants. The first part is focused on general information about Czech water treatment plants, followed by water treatment categorization using several criteria, and the most commonly used water treatment technologies in the Czech Republic. The fourth part of the thesis is concentrated on data acquisition and its evaluation. Last but one part is represented by description of the individually visited water treatment plant. Finally, the thesis is completed with a catalogue of basic information about selected water treatment plants.

Using the tertiary degree for water treatment
Kovačíková, Kristýna ; Kučera, Tomáš (referee) ; Biela, Renata (advisor)
Bachelor thesis will deal with water treatment options with greater pollution, when it is necessary to include after the secondary degree even the tertiary degree. It will be create an overwiev of equipments, which are suitable under certain conditions as tertiary degree and will be worked out a study with using of this degree. As part of this work is to create an overview facilities that are suitable under certain conditions, such as tertiary degree and next a study of water treatment with the use of this degree. The study designed middle water treatment plant and two sedimentation tanks, four european and three active carbon filters.

Study of water treatment plant from surface source
Inwald, Petr ; Látal,, Milan (referee) ; Biela, Renata (advisor)
The first part of the thesis deals with water sources and methods of drinkable water treatment. This section describes the technologies used for two-stage water treatment from a surface source. The second part deals with study of the new drinking water treatment plant from a surface source for Adamov town. The work documents the current state of the existing water treatment plant and describes used technology with a design flow Q = 30 l s-1. In the next part of thesis is design of two variations of new technological line with a design flow Q = 10 l s-1. The first variation is one-stage water treatment with pressure filters as the main separation stage. Two-stage water treatment is designed for the second variation, in which the first stage of separation are clarifiers and the second stage are pressure filters. Thesis includes drawing documentation of designed pressure filters and clarifiers, technological and height scheme of both variations.

Application of cavitation in industrial processes
Hamar, Oliver ; Tancjurová, Jana (referee) ; Rudolf, Pavel (advisor)
The bachelor thesis deals with the research of the application potential of cavitation technologies in various industries. Thanks to its properties, cavitation seems to be a promising tool for streamlining a large number of industrial processes in several aspects. The first part deals with the theoretical description of the cavitation phenomenon, its negatives and methods of their detection. The second part focuses on the analysis of possible usage areas of cavitation technologies and the ways of generating the cavitation, focusing on current research and findings in the area of hydrodynamic cavitation application.

Adsorption of natural organic matter (NOM) on granular activated carbon in the treatment of drinking water
Le Duc, Duy ; Mega, Jaroslav (referee) ; Dolejš, Petr (advisor)
In the first part of this thesis the methodic of lab trial was studied, which will be useful for studying adsorption of natural organic matter by activated carbon. As an optimal method of testing adsorption characters jar testing was chosen. Again as an indicator of organic contamination, it was decided to use permanganate chemical oxygen demand (in Czech CHSKMn) will be used. In the second part of this thesis the adsorption characters of eight types of granular activated carbon were studied. Those granular activated carbon came from two world produces, from company NORIT five type of granular activated carbon were tested: NORIT GAC 1020, NORIT PK 1-3, NORIT GAC 1240, NORIT ROW 0.8 SUPRA a TOD NORIT ROX 0.8 and from company Chemviron Carbon three types of granular activated carbon were tested: F100 FE11120A, F400 FE11210A a TL830 FE2028B. Batch kinetic tests of natural organic matter adsorption were conducted with all types of granular activated carbon at first. For description of sorption not only the batch kinetic tests and duration needed for setting equilibrium were observed, but also the process decreasing of concentration of natural organic matters to the value of equilibrium concentration known as adsorption equilibrium was followed.

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.

Sludge management of water treatment plants
Ševčíková, Ilona ; Bogáňová, Ida (referee) ; Biela, Renata (advisor)
This bachelor thesis deals with sludge management of water treatment plants. The aim of the thesis is to analyse posibilities of sludge treatment and describe sludge management in specific cases. This writing is divided into theoretical and practical part. Theoretical part deals with principles of water treatment, creation of sludge in water treatment plants with different number of separation stages, quality of sludge, sludge treatment, elimination or using of sludge. Practical part describes sludge management of six specific water treatment plants in the Czech Republic.
