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.

Dependence of Sludge Thermal Pre-treatment on its Dewatering
Žerava, Zdeněk ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
The first part of the thesis is focused on the problems related to sludge and evaluates sludge disposal from waste treatment plants. The thesis mentions factors influencing method selection of sludge disposal as well as it compares sludge disposal in the Czech Republic and in the other states of the EU. It describes a complete waste treatment line and sludge disposal in the area of sludge treatment and disposal. It deals with sludge disintegration and describes the most effective methods of disintegration. The second part of the thesis describes an experimental part of disintegration of waste treatment sludge. An experiment was conducted in the school laboratory in a way of thermal disintegration in the double-surface pressure tank. The disintegration was conducted to temperatures of 60 °C, 90 °C, 120 °C, 150 °C, and 180 °C. We monitored dependence of the sludge dry residue content on disintegration temperature as well as content of suspended solids in liquid fraction (FUGAT). It was possible to choose optimal temperature of disintegration in accordance with processed results.

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.

The influence of disintegration of the input material for the production of methane by anaerobic fermentation
Herman, Pavel ; Frýba, Lukáš (referee) ; Houdková, Lucie (advisor)
This master‘s thesis deals with the influence of disintegration of brewer's grains for the production of biogas by anaerobic fermentation. The first part introduces us with the issue of biodegradable wastes. There are given their characteristics, ways of handling with them and legislative restrictions associated with them. In other sections there is a detailed description of anaerobic fermentation itself, including characteristics of biogas. Then there is issue of disintegration during fermentation including a list and characteristic of some disintegration methods. The main part of the thesis consists of description of the experiments on which it is observed increment of biogas based on the disintegration of brewer's grains and the evaluation of the individual experiments including the calculation of economic of the disintegration in laboratory conditions.

Sludge pretreatment and its further utilization
Němec, Jan ; Dlabaja, Tomáš (referee) ; Elsässer, Thomas (advisor)
The thesis deals with methods of pre-treatment (disintegration) of sewage sludge, which offers an opportunity for better operation of a waste water treatment plant. The introduction is aimed at sewage water and sludge dividing, and then at their characteristics. In this thesis a current state of sludge disposal within the reference to the legislature and how to divide the methods of disintegration is also marked. Afterwards a description of selected methods of sludge disintegration, their comparison and the applicability of thermal disintegration to pasteurization of sewage sludge is included.

Brexit and its implications for European integration
Hecht, Petr ; Kučerová, Irah (advisor) ; Plechanovová, Běla (referee)
The diploma thesis Brexit and its implications for European integration uses the method of explanatory case study in an effort to analyze the causes and impacts of the Great Britain's withdrawal from the European Union. The thesis therefore examines the historical context of the complicated relations between Great Britain and the European Communities from their formation in the 1950s to the present, which ultimately led to the historic step of United Kingdom's withdrawal from the EU on 31 January 2020. The thesis then maps the negotiations regarding the Withdrawal Agreement and the future arrangement of mutual relations, which took place between 2016 - 2020. The effects of the UK's withdrawal from the EU on the composition and functioning of the European institutions and the impact of the changes on the remaining member states are also analyzed. In addition, the work presents possible arrangements of economic relations between the two parties, which are currently the subject of negotiations between the UK and the EU during the transitional period from 1 February 2020 to 31 December 2020. Lastly, the thesis works with the White Paper presented by the European Commission in 2017 in order to analyze five possible scenarios for the future development of European integration. For this, the thesis...
