Biodegradable waste
Dřímal, Jiří ; Niesner, Jakub (referee) ; Beňo, Zdeněk (advisor)
The goal of this bachelor is introduction with the issue of using biodegradable waste (BDW) in the EU. The introductory chapters are focused on the description of the different types of BDW. There are described ways of processing of this waste and their use. The emphasis is on mapping the current condition of treatment of biodegradable waste with it in the EU and the CR.

Biological pretreatment sewages water
Veselý, Václav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
Bachelor's thesis deals with waste water purification at the stage of pre-inflow of water into the biological waste water treatment plants. It is divided into two parts, a theoretical and calculation. The theoretical part deals about sewage water and the method of biological treatment. Design proposal is part of the activation tank for quantity EO.

Losses in a pipe line because of the flow of mixed substratums
Vlasák, Bohdan ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
Introductory part of this thesis is aimed on theoretical description, principle and building of biogas stations, which require solution of many different problems. A specific group of the problems concern transport of mixed substrates of different concentrations both in and outside the area of biogas station. A major part of the substrate transport is done by pumping it in pressure pipeline. Experimental work consists of design and description of a measuring circuit. Graphic characteristics for water and gas loss levels are drawn from the measured readings. Multiples of pressure losses by flowage of substrates with different levels of dry basis are graphically expressed with a help of correction coefficients.

Utilisation of biomass in the Czech Republic
Galčáková, Alena ; Beňo, Zdeněk (referee) ; Bělohradský, Petr (advisor)
The bachelor’s thesis deals with the issues of biomass utilization in the Czech Republic. The introduction generally summarizes the sources of energy. Next follows the discussion about biomass as one of the alternative source of energy. The main part of the thesis focuses on the facility, namely on the boiler house, which utilizes the biomass as fuel. The facility provides the heat to the major part of town Bystrice nad Pernstejnem with almost nine thousand inhabitants. In the conclusion it is mentioned economical and ecological summary of the boiler house.

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.

Legislature of the waste disposal and utilization of biodegradable materials
Pešl, Milan ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The aim of this work is to give information about the issue of legislation of disposal and reuse of biodegradable waste. Legislation in the field of bio-waste in the Czech Republic and the EU is grouped into various laws and guidelines which describe particular conditions of the dumping of wastes, their subsequent processing and reuse. In this work, the definition of BDW, its composition and the current state of dealing with this type of waste in the EU and the Czech Republic is mentioned. Different methods of processing biodegradable waste, which include incineration, composting and anaerobic digestion, their advantages and disadvantages are described in this work. There are also introduced examples of BDW in the EU and the Czech Republic there.

Production of ethanol from renewable materials
Čmaradová, Miroslava ; Beňo, Zdeněk (referee) ; Houdková, Lucie (advisor)
This Bachelor thesis focuses on the production of ethanol from renewable resources, in particular alcoholic fermentation. Briefly mentioned is the waste legislation. Closer described the materials from which the ethanol produced and can be broken down properties and behaviour of ethanol. Briefly describes the history of the production of ethanol. It is further discussed the current form of the production and use of ethanol.

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.

Heat balance of anaerobic part of sewage treatment plants
Řezáč, Jaroslav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
This thesis is focused on anaerobic stabilisation of sewage produced by sewage treatment plant. Mesophilic stabilisation was chosen for the sewage treatment plant . In the first chapter, main attention is dedicated to general treatise on sewage treatment plant. Anaerobic process of stabilisation, digestion tank and some of the medium are characterised there. Next chapter is dealing with thermal balance for selected version of sewage stabilisation. A proposal of digestion tank and thermal insulation is also made there. Further, heat exchanger, boiler and combined heat and power unit are projected.
