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.

Biogas plant design
Kocián, Oldřich ; Pěček, Jan (referee) ; Houdková, Lucie (advisor)
The diploma thesis is focused on possibility of usage biologically decompostable wastes in the biogas plant. The first part of this thesis describes principal production of the manure gas and as well concrete biogas plants, where are shown different approaches and technologies. The main target of the thesis is based on biogas plant design for manipulation with biologically communal wastes from VUT v Brno and chosen parts of Brno. To the proper design of the biogas plant precede evaluation of accesible wastes from choosen localities. Since we consider wastes from households, the way of collection of those wastes is designed. The thesis also consider economic balance and assesment of the biogas plant. Investment costs are predicted, process costs are evaluated and as well profit from selling of the electric energy is consider, profits from charges for manipulation with wastes and profits from selling of compost.

Methods of sewage sludge thermal treatment
Rosendorfová, Lenka ; Pavlas, Martin (referee) ; Houdková, Lucie (advisor)
The first part of this diploma thesis targets in the formation of summary of methods of sewage sludge thermal treatment. Sludge is dangerous material rising from water treatment. Original water pollution is concentrated in sludge. Spectrum of the different methods of sludge disposal is very vast, thermal methods belong to the most advanced ones. Nowadays, legislative rules and regulations make more restrictive, hence sludge disposal is problematic because of economic and ecological view of point. The second part of this diploma thesis is dealt with perspective sludge management at the Central Waste Water Treatment Plant Prague concerning sludge drying and consequent sludge incineration.

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.

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.

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.

Biomethane treatment in European region
Gutovský, Jan ; Houdková, Lucie (referee) ; Niesner, Jakub (advisor)
The main aim of this thesis is to provide information about biomethane production and its use in Europe. The thesis contains a brief description of the production of biomethane and a summary of the basic processing methods. The following section discusses the current utilization of biomethane in selected European countries. It focuses on describing the state of technology and regulations in these states.

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.

Hydrogen production from renewable sources
Balko, Michal ; Kropáč, Jiří (referee) ; Houdková, Lucie (advisor)
The goal of this bachelor's thesis is to make a summary of actual hydrogen production possibilities both from fossil fuels and from renewable sources. First part deals with production by steam reforming of natural gas and water electrolysis. Next comes the production from biomass by photofermentation and fermentation. Attention is paid especially to input materials and process conditions. In the end chosen processes of production are compared by their energy intensity found out by simplified calculation.

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.
