The application of chlorine for public swimming pool water disinfection
Wagnerová, Andrea ; Svoboda, František (referee) ; Biela, Renata (advisor)
The bachelor thesis focuses on issues surrounding disinfectants of swimming pool water. The dissertation examines various chlorine based disinfectants as well as chlorine free disinfectants. Part of the thesis compares advantages and disadvantages of different possibilities of securing hygienic swimming pool water. Several complexes of public swimming pools in Brno and its neighbourhood were visited in order to examine the methods of disinfection, which are currently used at those swimming pools. Disinfectants based on chlorine are currently used the most for swimming pool water.
Specific substances in drinking water sources
Konečný, Jiří ; Kučera, Tomáš (referee) ; Biela, Renata (advisor)
In this bachelor thesis I dealt with specific substances which occures in sources of drinking water and pollutes quality of water. Especially its heavy metal, sulfur compounds, nitrogen, phosphorus and other. In this thesis I deal with possibilities about remove of these substances by using various methods, especially absorption on filter materials. These thesis is focused on using absorption on suitable materials for reduction of concentration arsenic and cadmium in drinking water. In first part I‘ve characterized subtances which occures in the water and outlined a way to remove them. Second part is focused on laboratory observation to efficiency of removing arsenic and cadmium on sorption materials.
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.
Removal of Specific Pollution in Water Treatment
Tázlerová, Radka ; Vašalovská, Petra (referee) ; Kučera, Tomáš (advisor)
The present work deals with the specific problem of pollution in drinking water sources and potential removal of these substances in water treatment for drinking water. Attention was focused on hormones, pesticides and heavy metals. There have been reports of their properties, occurrence, impact on the environment and humans.
Removal of different species of phytoplankton by dissolved air flotation
Sukopová, Martina ; Mega, Jaroslav (referee) ; Dolejš, Petr (advisor)
The work evaluates the efficiency of dissolved air flotation (DAF) in removal of various kinds of phytoplankton. As absolutely necessary in the process of water treatment proved the agglomeration phase, or coagulation and floculation. This phase neutralizes the particles so that they can fasten air bubbles. The efficiency of this process depends on several variables, though: the kind of coagulant used, dose, coagulation pH, duration of floculation and its intensity, recycle ratio and the polymer use in coagulation. The particle size volume distribution and the volume of organic matter in raw water also have certain influence on phytoplankton removal. Dissolved air flotation is currently the most suitable method of phytoplankton removal. It can remove 93-98 % of blue-green algae and even 99-99.9 % of algae. The efficiency of flotation was also compared to sedimentation for the economic reason. In the process of water treatment, the sedimentation is now being replaced by flotation.
Removal of iron and manganese from ground water sources
Lízalová, Zuzana ; Kučera,, Tomáš (referee) ; Biela, Renata (advisor)
The thesis deals with removal of iron and manganese from ground water in drinking water treatment. The aim of the thesis is to describe the possibilities of removing iron and manganese from ground water, including an overview of the specific devices used by water technology companies for removing iron and manganese from ground water sources.
The Photo-Degradation of Organic Pollutants Using Sulphonated Phtalocyanines of Zinc and Aluminium in Semi-Industrial and Industrial Reactors
Hejda, S. ; Bůžek, D. ; Klusoň, Petr
The main aim of the work was to test the photocatalytical cleaning of organically polluted waters in a semi-industrial reactor, to optimise the reactors parameters (e.g. flow, initial concentrations of pollutant and catalyst, reaction mixture volume, etc.) and then to test the reactors for 4-chlorophenol (as a model substrate) decomposition.
