Design of equipment for thermo mechanical pre-treatment of biodegradable waste
Kolařík, Ivo ; Jedlička, Filip (referee) ; Beňo, Zdeněk (advisor)
The main objective of this master’s thesis is to develop design equipment for thermomechanical pre-treatment of biodegradable waste. An important aspect of the design is taking into account current legislation, sanitary conditions for determining the pre-treated biodegradable material, which also serves as a raw material for biogas production. So the device will be used to monitor the impact of thermomechanical pre-treatment of biodegradable waste for biogas recovery. The following describes the processes of anaerobic decomposition of biodegradable materials and technology, whose main task is intensification of anaerobic decomposition of organic materials. The theoretical work are given various methods of processing and utilization of biodegradable wastes, focusing on kitchen waste and sludge from sewage plants. The next section describes the various factors that may affect the stability of the process of biogas generation. This also results in yield and chemical composition of biogas. A key part of this master’s thesis is to develop technical documentation and an approximate calculation of the hot slurry.

Hydrogen Production from Biomass
Ožana, Ferdinand ; Beňo, Zdeněk (referee) ; Houdková, Lucie (advisor)
First part of this master´s thesis decribes the basic properties of hydrogen, its utilization in industry and economy. Greater attention is focused on the possibilities of hydrogen produciton. Next part describes anaerobic fermentation and optimum conditions for hydrogen production. The main part of the thesis deals with posibility of hydrogen production in an experimental laboratory unit using brewer´s grains as a primary material. The experiment was aimed to find suitable process conditions for hydrogen production. The quantity of produced gas and his quality depending on the amount of brewer´s grains and frequency of the dosage was observed. Based on the experiment, some recommendations are proposed for further research. An automatic feeding system is the most important of them. It will improve the quality of experimental work. A separate chapter is devoted to the automatic feeding system.

Anaerobic digestion of sludge from pulp and fodder yeast production
Řezáč, Jaroslav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
The thesis aims to identify suitable and in the locality available raw materials to a commnon fermentation with sludge from pulp and fodder yeast production in company Biocel Paskov a.s.. Introductory chapter briefly describes the mechanisms of penetration of the sludge itself. The following section deals with origin, chemical composition and properties of biogas. The factors affecting the production of biogas are described. A key part of this thesis is a performance of sludge fermentation test and selected mixed substrate. Acquired knowledge is evaluated and the optimum composition of input raw materials with regard to maximum, but also economic recovery of biogas selected. Further, on the basis of obtained data a rough draft of biogas station is done, icluding its energeic and economic balance.

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.
