Sludge Utilisation from Pulp and Paper Plant
Zemanová, Kateřina ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
The contens of diploma thesis is description of paper and pulp production and analysis of contemporary problems with disposal of sludges rising on industrial waste water treatment plant. Accent is focuses on description of waste water treatment technique, characteristics of rising sludge and the ways of his liquidation in particular plant for pulp production. Fundamental part of this project is evaluation of power and economics balance of current sludge technology in company Biocel Paskov a.s. and suggested sludge management technology. Balances are based on data gained from measurement in laboratory and on data gained from literary research.

Cleaning of biogas by the PSA (pressure swing adsorption)
Navrátil, Petr ; Houdková, Lucie (referee) ; Leštinský, Pavel (advisor)
The topic of this master thesis is upgrading of biogas. As a mixture of gases produced during anaerobic digestion, contains methane which is highly energy valuable gas. But also other substances that we want to remove. We will present the motivation for upgrading biogas and the possibility of separation, generally the pressure swing adsorption method. The key parameter of this technique is the choice of a suitable adsorbent. This is possible based on the knowledge of adsorption processes, therefore, is also described below. The objective of this thesis is to determine the parameters of the pressure swing adsorption metod. To do this it is necessary to determine the adsorption capacity of the adsorbent, measure breakthrough curves of carbon dioxide and methane, and determine the pressure drop of solid bed, etc. As a result we can finally make a balance and evaluate the applicability in practice.

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.

Radioactive Waste in Hospital Facilities
Bradáč, Antonín ; Houdková, Lucie (referee) ; Tabasová, Andrea (advisor)
The thesis is focused on a little-known issue of institutional waste produced by hospitals, the creation, collection and subsequent disposal. This thesis described the distribution of waste from various aspects, especially the characteristics and their subsequent use in the effective elimination. This thesis deals with not only this issue, but trying to get closer to negative impact of ionizing radiation on the human body, not only in the current level of radiation protection, but also in terms of the historical development of different sources and work with them, especially in connection with the use of ionizing radiation in normal human activity but also through the list of nuclear accidents. The practical part of this thesis compares the three types of hospitals primarily on the basis of a personal meeting with the heads of various departments involved in the management of institutional waste, and materials derived their visit. Specifically, the hospital Atlas and Tomas Bata Regional Hospital (both situated in Zlin) and specialized workplace Masaryk cancer institute in Brno.

Hydrogen Production from Biomass II
Matějka, Pavel ; Lisý, Martin (referee) ; Houdková, Lucie (advisor)
This master thesis continues the master thesis Výroba vodíku z biomasy. In that work were performed first experiments of hydrogen production from beer less by dark fermentation. Further experiments will continue based on previous experiments. For the energy balance were used results from [1] and data obtained from literature searches, because the results of the experiments were not entirely satisfactory. Energy balance was calculated for a laboratory fermenter to evaluate the efficiency of energy obtainable from the hydrogen produced by fermentation in a dark laboratory conditions. It was compared the yield given in [1] and yield derived from a literature review. The conclusion presents recommendations for further research.

Treatment of waste gases polluted by freons
Frydrych, Tomáš ; Houdková, Lucie (referee) ; Dvořák, Radek (advisor)
This thesis inquire into experimental decomposition of freon R-22 (CHClF2 - chlorodifluorometan) for different process conditions, by the help of pilot experimental unit in heavy laboratories DEPARTMENT of process and enviromental engineering Brno. This unit can decomposition waste gas, as the case may be combustion gas by the thermic oxidation or catalytic oxidation. Ground was in theoretical research, in which had been executed decomposition of freon R-22 in laboratory. In terms of experimental work were to be execution states for decomposition of freon R-22, next will be decomposition of freon R-22 by catalytic oxidation on catalyst Pt/Al2O3 and consequently this experiment will be analyse. Part of this thesis is exploration of facts basic way to decomposition of freon R-22, accounting of experimental unit and discussion of results.

Mathematical model of solar drying of sewage sludge
Ficza, Ildikó ; Houdková, Lucie (referee) ; Hájek, Jiří (advisor)
Solární sušení je mimo jiné energeticky nenáročná a tudíž vysoce ekologická cesta pro zpracování kalů z malých čistíren odpadních vod. Výsledkem tohoto procesu je produkt, který je velmi dobře použitelný v zemědělství jako přírodní hnojivo. V rámci této práce bude sestaven zjednodušený dynamický model sušení vrstvy kalu s jednou prostorovou souřadnicí. Tento model bude diskretizován pomocí vhodné numerické metody a bude provedena jeho implementace do výpočtového programu v prostředí MATLAB.

The Production of Wastes in Nové Město na Moravě
Švehlová, Tereza ; Houdková, Lucie (referee) ; Tabasová, Andrea (advisor)
The work deals with the analysis of waste site in town Nové Město na Moravě. The theoretical part contains a general view of waste management, distributed according to different perspectives, basic concepts and waste management legislation. The practical part is the analysis of waste in this area in 2009, 2010 and 2011, which is supplemented by processing the results of a questionnaire created by me.
