Design of WWTP at locality with extreme demands on quality of treated wastewater
Krupica, Radek ; Vachovec, Roman (referee) ; Hlavínek, Petr (advisor)
This diploma thesis deals with the wastewater treatment technologies by means of which high quality of the treated wastewater is attained, especially with regard to removing nutrients. The introduction of the thesis contains, among others, descriptions of the reserves in the Czech Republic where it is extremely important to insist on the highest quality of the discharged wastewaters. Then follows a summary of the quality requirements on the discharged wastewaters as stipulated in the legislation. Furthermore, I analyse the impact of the nutrients – nitrogen and phosphorus – on the environment and the principles of their removal from the wastewaters. In the next section I concentrate on the technological processes by means of which the required quality of the wastewater is achieved. The conclusion includes a list of technologies used as the tertiary wastewater treatments with emphasis on membrane technologies. The second part of my thesis is a study of a project of a wastewater treatment plant (WWTP) with membrane technology for the villages of Sloup and Šošůvka located within the protected landscape area of Moravian Karst.

Brown Coal Power Plants in Czech Republic
Šperka, Radim ; Šnajdárek, Ladislav (referee) ; Špiláček, Michal (advisor)
The thesis describes brown-coal power plants in the Czech Republic. The first part discusses brown coal as a mineral raw material, its mining in the Czech Republic, the impact of mining on the environment and ecological territorial limits.. The second part deals with the Thermo-dynamic working cycles in the power plant. Also deals with various technological parts of brown-coal power plant, including equipment and procedures for the cleaning of exhaust gases. The last part describes the most important individual brown-coal power plants in the Czech Republic, their brief history, the technical parameters and the planned service life.

Microfauna of the activated silt from the biological sewage disposal plant in Kroměříž region.
Hrudíková, Radka ; Illková, Kateřina (referee) ; Omelková, Jiřina (advisor)
Bachelor thesis deals with the description and evaluation of micro fauna of activated sludge biological sewage waste water in Kromeriz region. Furthermore, morphological description and evaluation of sludge flocs. The thesis describes the types of biota (biocenosis), which may occur in the activation tanks. There are also mentioned other incidental methods of sewage treatment such as mechanical, chemical and physicochemical methods. The experimental section describes the experiment procedure, apparatus and methods use for assessment of activated sludge. In the results the data are processed into the synoptic charts and the accompanying tables. At the end the results are evaluated.

Denitrification in soils with different nutrient inputs
ŘÍHOVÁ, Gabriela
The aim of this thesis was to estimate denitrification activity in four agricultural soils which are managed differently regarding type and amount of fertilizers. Potential denitrification, soil respiration and denitrifying enzyme activity were determined in laboratory experiments. In additional experiment, the impact of changes in soil pH on denitrification characteristics was studied.
