Problems with sulphur and silicon in biogas
Holub, Radim ; Jecha, David (referee) ; Beňo, Zdeněk (advisor)
The main objective of this bachelor’s thesis is a description of a composition of biogas (BG) and contained undesirable components, which include especially sulphur and silicon compounds. In an introductory chapter is given a definition of the biogas, principle of its creation, chemical composition and a share of undesirable components. In following chapters are described single undesirable components, their properties and negative impact on parts of equipment using biogas. The following are the methods to reduce the critical concentration values of these components or their complete removal from biogas. In the thesis are also given practical solutions to eliminate these undesirable components.

Utilization of biodegradable waste
Švec, Jan ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The aim of this paper is to summarize the current situation of the problem using biodegradable waste. The introductory chapters deal with descriptions of different types of biodegradable waste. The main part describes ways of handling this waste. For various types of waste are listed by their most appropriate treatment and further use. Emphasis is placed on legislation dealing with that waste legislation on the processing equipment.

Design of Sludge Disintegration Unit
Brtna, Filip ; Beňo, Zdeněk (referee) ; Boráň, Jaroslav (advisor)
The target of the first part of this diploma thesis is focused on the problems relating to the sludge production from the wastewater treatment plant and subsequent sludge treatment. In this thesis complete process of the wastewater treatment is described. Predominantingly is described the process in digestion tanks, therefore stabilization process, whereas the paper is focused on sludge pre-treatment (disintegration) of waste activated sludge before stabilization. The second part of this thesis is focused on the design of the disintegration unit for the wastewater treatment sludge in assist with experimental data. According to measured and fixed parameters the unfired pressure vessel has been designed. On the vessel has been further realized the strength calculation, the heat balance and the economic balance.

Comparison of aeration elements
Stříž, Michal ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
The content of the thesis is to compare the aeration elements used in the aeration tank for biological treatment of wastewater. In order to compare, the work contains description and explaination of: ? basic division of functions and some aeration systems, ? transfer of oxygen, ? the use of pure oxygen instead of air, ? placement of aeration elements into the activation tank. Since the aeration elements are plentiful, work is focused on the most widely used pneumatic and mechanical aeration systems.

Biogas composition
Čekanová, Adéla ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
Content of the submitted bachelor thesis is a description of biogas chemical composition with following analysis of each unit, especially majority units, with use of different gas analysis methods. Main emphasis is set on biogas units which have undesirable effects while using it as energy source and on possibilities of removing them using set technologies. In larger scale the bachelor thesis is concerned with teoretical possibilities of removing sulphur from biogas and following methods used in work experience.
