Treatment of waste from biogas plants
Budín, Oto ; Frýba, Lukáš (referee) ; Vondra, Marek (advisor)
This bachelor thesis is focused on options of treatment of waste from biogas plants. The first part of this thesis describes biogas plants and its working. The main target of the thesis deals with waste from biogas plants – its creation, properties, composition and application. The thesis also includes an overview of legislative and environmental restrictions applying to the treatment of waste from biogas plants. The bachelor thesis also comprises an information about biogas plants Stanoviště.

Proposal for measures to increase the efficiency of particular biogas station "Měčín" in the district Klatovy
MACH, Stanislav
The thesis is mainly aimed at agricultural biogas stations. The theoretical part is focused on agricultural biogas stations operation and the use of generated waste that is produced there. The practical part describes the economy, technology and the operation of the agricultural biogas stations Měčín. Further, the thesis suggests some measures to increase the efficiency by selecting appropriate substrates and especially the utilization of waste heat, which is not significantly used by the company.

Proposal for measures to increase the efficiency of biogas station Obora
NOVÁKOVÁ, Renata
In my thesis, entitled "Proposal for measures to increase the efficiency of biogas station Obora" in the theoretical part deals with factors affecting the efficiency of biogas plants. The practical part focused on the specific biogas plant solves the technological and economic aspects of the station. It also deals with waste heat produced during electricity generation, feedstocks, the use of digestate and biogas station linked with the adjacent farm. The thesis also discusses the problems with which the biogas plant in Obora meets, which have significant impact on the efficiency of the biogas plant.

select suggestions for increasing the efficiency of biogas plant in Koloměřice.
ČERVENKA, Pavel
In my bachelor thesis I will try to introduce the topic of importance and operation of biogas plants. The theoretical part focuses on the entire operation of biogas plants, types of biogas plants, the inputs and outputs and processes. The goal of the practical part was to describe the biogas plant in Koloměřice, make out the processing of by-products and select suggestions for increasing the efficiency of biogas plant in Koloměřice.

The use of the reactor with sludge cloud and external biomass separator for methane production from the substrate for Biogast Plant
ŽIVNÝ, Jakub
The aim of the study was to compere the reactor with sludge cloud and external separator biomass in different modes. This typ of reactor is principally used in wastewater treatment and in this work was designed for production of biogas from biosmass, commonly used in agricultural biogas plants. The reactor assembly was prepared in the laboratory of the available glass flasks, connected by rubber tubing and mixing pump. The entire device was immersed in a water bath heated thermostat. For the purpose of this work was used samples from biogas Týnec near Dobrovice at Mladoboleslavko. The reaktor was injectable liquid portion, formed after adjusment method IFBB (Integrated Generation of Solid Fuel and Biogas from Biomass). The principle of this method consists in separating the liquid and solid components of biomass. Operation of the reactor was carried out in three stirring models: without stirring, medium stirring, intensive stirring. Further, the operation was compared at 40°C and 53 °C in a mode without stirring. This monitoring is carried abut for five hours. The specimens was taken every hour and after drying to COD (determine chemical oxygen demand), which expresses the degree of degradation of organic matter. The results show that the laboratory devie model stirring does not show. However, the temperature change from 40°C to 53°C showed an increased degradation of organic matter.

Biogas Plant and its impact on the environment.
MACH, Marek
In my work I try to bring the topic of meaning and operation of biogas plants and their possible noisy burden on the surrounding environment, especially in populated parts of the municipalities in which the biogas plants are located. The theoretical part is focused on all traffic biogas, from their division, despite possible inputs and outputs, and the processes that happen inside the station. The theoretical part also contains noise that can be issued for machinery undisturbed environment. The practical part of this work was to measure the noise emitted by the station at full capacity, and if possible under all operating conditions, such as management of raw materials and export of digestate. From the measured values, we will try to determine if stations do not affect the life of the surrounding communities and their residents.

The apply digestate at operate of biogas plant agricultural type
ČÁPOVÁ, Aneta
Comparing inputs needed to operate biogas stations, this Bachelor paper focuses on the composition of digestate and on its use in five examined stations. The paper is split into two sections: theoretical and practical. The theoretical section, i.e. a summary of relevant literature, explains the basic concepts and other issues related to the biogas proper, biogas generating stations, substrates and digestates. The practical section deals with experimental data obtained from the five stations. The data were acquired through a questionnaire wherein the stations' operators described their facilities while specifying the parameters; substrates applied; methane yield figures; results of digestate analyses; and their methods of application.

Production and usage of biogass in South Bohemia
KALINOVÁ, Lenka
The bachelor's thesis deals in particular with comparison of biogas production in individual biogas stations in the South Bohemian Region. In addition, the thesis describes fundamental parameters such as year of commissioning, installed electric output, installed thermal output, input material and employed technologies. Based on the foregoing information, it is possible to conclude that the individual biogas stations have a positive impact not only on the utilization of the produced biogas for energy purposes but also on the environment, waste degradation, reduction of the risk of contamination and acquisition of high-quality fertilizer.
