Energy performance of wastewater treatment plants
Čížová, Barbora ; Bogáňová, Ida (referee) ; Hluštík, Petr (advisor)
The retrieval part of the bachelorś thesis deals with legislation concerning energy audit and energy audit processing at wastewater treatment plants. Further work is aimed at assessing the energy performance, energy optimization and operation of energy self-sufficiency wastewater treatment plants. The practical part is focused on the comparison of the specific energy consumption for wastewater treatment in Koprivnice. The aim is to assess the energy performance of the selected indicators. This is an assessment of the m3 of waste water, kg BOD5 removed and the number of population equivalent.

Assessment of the impact of different types of RES in the power system
Zmeškal, Pavel ; Matoušek, Antonín (referee) ; Mastný, Petr (advisor)
This thesis deals with usage of each kind of RES under conditions of Czech republic and their usage at areas placed in. Consequently supplied RES output power at time and its influence on reliability of supply in EPS CZ. Way of operation of RES from point of view of requirement on regulation and control of operation of EPS is more studied on operation of different kinds of wind power plants, which due to its variable output power affects not only EPS CZ. At final caption, economic influence of RES to EPS is reviewed as a unit, increasingly claims on regulation, increasingly benefit on support of RES. All these influences increase price of electricity for end user.

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.

Fuel for internal combustion engines
Vrbický, Jiří ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
This thesis is concerned with basic features of fuels for internal consumption engines, especially their influence on thermal efficiency. It also introduces dividing of fuels and their compare in ecologic, economic and technologic side. It is concerned convectional fuels (gasoline, diesel oil) and alternative fuels (nature gas, bottled gas, hydrogen, biodiesel, biogas, methanol and ethanol).

Design of Biogas Cleaning Technology
Šrámek, Zbyněk ; Milčák, Pavel (referee) ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
Thesis aims to design suitable technology for biogas treatment so that its output can be used as a fully equivalent fuel for vehicles. First part introduces reader into an area of biogas treatment. Second part describes in detail chosen method, technology of membrain separation. In third part, current conditions in Czech republic were discussed. Fourth part adresses the aplication of membrane technology into existing biogas station via side-standing reaserch container. The end of the thesis is focused on selection and proper desing of blower, which will be transporting raw biogas from biogas fermenters into research container.

Disintegration of sludge thickened by flotation
Veverka, Jakub ; Jecha, David (referee) ; Houdková, Lucie (advisor)
The main topic of this thesis is a research of influence of disintegration of sewage sludge on the production of biogas during the process of anaerobic fermentation. The theoretical part deals with issues and specific methods used during the process of waste water cleaning, furthermore it contains simplified description of waste water treatment plants and particular devices. The number of ways of processing sewage sludge and its potential utilization id also discussed. Following parts of the thesis analyze in detail my own process of anaerobic fermentation including important factors influencing this process. Comparison of aerobic and anaerobic fermentation and ecological perspective on the issue are included in this part. Another important part of the thesis deals with disintegration and description of the disintegration methods and devices. The fundamental part implies the analysis of the executed experiments. Experiments analyze the growth of biogas during anaerobic fermentation depending on the disintegration of sewage sludge. After that the evaluation of the experiments is stated together with economical calculations of the disintegration process executed in laboratory conditions.

Production of biogas as an automotive fuel from renewable materials
Frühbauer, Zdeněk ; Houdková, Lucie (referee) ; Dlabaja, Tomáš (advisor)
The aim of this thesis is to specify and summarize possibilities of biogas production as a motor vehicle fuel by using the renewable energy sources. In the first part of the thesis there are the data concerning biogas, its production and chemical composition. An important part of the thesis is a description of current most used methods of cleaning which adjust biogas to quality of natural gas. The important part of this thesis is to introduce some of already working projects and to get knowledge about possibilities of making biogas from biologically decomposable material as a renewable energy source. The close of the thesis deals with energy, economy and ecological audit too and values biogas through all angles which decide about its using in larger size in the car industry.

Electricity generation from biogas
Kovář, Martin ; Houdková, Lucie (referee) ; Pavlas, Martin (advisor)
The main goal of this bachelor thesis is an analysis and description of a combined production of thermal and electrical energy from biogas. Biogas belongs to the category of renewable energy. The first part is devoted to the biogas production. There are also described its properties and its comparison with other alternative fuels. The second part describes the principles of available cogeneration systems and their parameters. Design and analysis of a cogeneration system for a given biogas plan. Evaluation the economic aspect of cogeneration.
