Energy Optimization of WWTP
Frank, Ivo ; Sousedík, Milan (referee) ; Hlavínek, Petr (advisor)
Objectives of this bachelor thesis are to offer a brief tutorial on how to proceed with the energy audit of the wasterwater treatment plant and offer energy-efficient and economical alternatives to the technologies and equipment currently used for mechanical and biological wastewater treatment processes. Chapter with practical part of the thesis deals with possible applications of retreived knowledge on to operations of WWTP Mikulov in order to optimize its energy efficiency.

Control and visualization of sewage treatment plant
Monček, Matej ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
The theme of this bachelor thesis was to introduce with wastewater treatment plant issue and design adequate control system. There is short historical overview in the introduction and acquaintance with reason of creation the specific issue. Which is wastewater treatment plant. In the next parts is description of water treatment, technological analysis acquaint with technological base and used Technologies and preliminary design of graphical and functional parts of control program SIMATIC S7-300.

Possibilities of using small hydroelectric power plant in the wastewater treatment plant
Krúpa, Lukáš ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This bachelor’s thesis focuses on the possibilities of using small hydroelectric power plant in wastewater treatment plant. The first part is theoretical and describes the theory of wastewater treatment plants, small hydro power plants, turbines and generators. The seconds part focus is to describe the design of small hydro power plant. It begins with description of location then continues with calculation of Banki turbine and ends with generator selection. The last part deals with an economic evaluation, which includes estimating of the investment costs, the price of saved electricity and determining the estimated return on investment. In conclusion the thesis compares the ways of using the produced electricity.

The draft of family house with focus on the ecological water management
Stupavská, Jaroslava ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The aim of my work is an optimal design of a detached house focused on ecological management of rainwater and household waste water. The work is divided into four parts: the first part deals with the design of the family house, the second part describes water as a medium used in households, in the third part I am dealing with packed home waste water treatment plants, and in the last, the four part, I approach the issue of root waste water treatment plants. My priority is the design of the family house with a water – saving solution. For the designed family house in Velká nad Veličkou, sewage treatment is provided by a vertical root waste water treatment plant, accumulation in the pond together with the filtered rainwater and their reuse in the facility as service water and in the garden irrigation. In the practical part of water management is the design of a sludge management facility. As the grassland is located around the house, a suitable irrigation solution is the location of the sprayers. Thanks to this type of solution, it is possible to save considerable money in management of drinking water and also to improve the microclimate site where the designed family house was built. In my work I wanted emphasise each household is able to efficiently and economically handle rainwater and waste water that can have a great impact on the water cycle in nature.

Assessment of the efficiency of wastewater treatment plant using ecotoxicity tests
Urminská, Barbora ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
The possibilities of environmental pollution control are increasing and more advanced wastewater treatment methods are being emphasized, as well as more specific control of contaminants presence in treated waters. That is why it becomes relevant to perform not only chemical analysis but also ecotoxicological bioassays as the means of evaluation of biological effects caused by wastewater discharges to ecosystems. No wastewater treatment plant is able to treat the water perfectly – it can only decrease the pollution level to an acceptable value. Therefore it is important to find out if the treatment process is sufficient to provide a satisfactory decrease of ecotoxicity and also what effects to the organisms in recipient will be caused by wastewater discharges. The thesis is focused on the evaluation of wastewater ecotoxicity. In the experimental part of the thesis, wastewater samples were collected at four wastewater treatment plants in the Czech Republic. At one of them also the sludge samples were taken. The aim was to evaluate the efficiency of wastewater treatment by selected ecotoxicological bioassays. The results have shown that the efficiency of wastewater treatment plants with secondary treatment is sufficient to reduce acute toxic effects to the minimum. Average toxicity removal was over 80 % at three of four evaluated wastewater treatment plants. At the fourth WWTP it was 41 %, however, at this WWTP high efficiency of treatment is not necessary.
