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.

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.

The impact of the debt crisis on monetary integration in Europe
Pecho, Maroš ; Čajka, Radek (advisor) ; Hinčica, Vít (referee)
The bureaucratic structures of European Union, Eurozone etc.; deal with the issue of monetary integration these days. This point was achieved, because of the beginning of debt crisis, which has erupted in 2009. In this thesis is a clear explanation of monetary integration in general, hers costs and benefits and also historical development within the framework of monetary union in Europe. The emphasis is placed on creation reasons of debt crisis, with detailed description and interpretation of the global imbalances principle, applied on Eurozone members. In the part discussing global imbalances are stated PIIGS states and their main task within the framework of debt crisis. The most important part is the part, noticing the concrete steps in European integration deepening such as formation of stability mechanisms -- EFSM, EFSF, ESM; continues to preparation of formation named as bank union; introduction of financial transaction tax etc. The might and theoretical solutions, like Eurobonds or disintegration of Eurozone, are also included. The last paragraph sums up impact of debt crisis on integration processes.
