Industrial wastewater in Czech republic
Sikora, Petr ; Konečná, Eva (referee) ; Vondra, Marek (advisor)
The aim of this bachelor thesis is to provide a comprehensive insight into various aspects of industrial wastewater production in the Czech Republic. In addition to studying industrial wastewater in general, it also focuses specifically on winery wastewater. Wine production represents an alternative to another drink very popular among many Czechs – beer. To better understand this topic, the thesis combines a summary of theoretical knowledge with up-to-date statistics regarding production and emissions of industrial wastewater using data provided mainly by Ministry of the Environment of the Czech Republic, Czech Statistical Office, and Pollutant Release and Transfer Register. The results can be used for monitoring the development of quality and quantity of wastewater emissions during recent decades, as well as responses to various influencing events and factors. An overview of important legislation documents regarding this topic is included as well, followed by a brief selection of emission standards.

Water Quality Monitoring in the Selected Water Supply System
Janišová, Marie ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
The aim of the bachelor thesis is to assess the quality of the water in the water supply system and the influence of the distribution system on the quality of the transported water. The first part of thesis defines the theoretical basis on which it is based on practical part. The next part contains information about the area, the distribution systém and water analyzes. This is followed by its own series of water analyzes and the analysis of the resulting values of water quality indicators. The last part of the thesis evaluates the influence of the network on the water properties and has been designed measures to eliminate the adverse effects of the water supply.

Removal of selected metals from the water
Pěkný, Mojmír ; Vybíralová, Pavla (referee) ; Biela, Renata (advisor)
In my thesis I focused on the problem of removal of some heavy metals from water. Heavy metals cause deterioration of quality of water sources and bring about a need of complicated water treatment technologies. In particular it is the case of mercury, arsenic, cadmium, lead, chromium and nickel. This diploma thesis focuses on the utilization of adsorption using suitable adsorption materials to reduce concentrations of nickel in drinking water. At the same time it investigates the effectiveness of these materials in the process of removing iron and manganese from water. The first part of my thesis presents an overview of these metals. I write about their occurrence, its forms, properties and significance. The second part of the work focuses on the laboratory observations of the effectiveness in removing iron, manganese and nickel from water. The description of the used sorptive materials is also included.

Water quality analysis using colorimetry
Kovaldová, Eliška ; Zumberg, Inna (referee) ; Čmiel, Vratislav (advisor)
This bachelor's thesis deals with the analysis of water quality using colorimetry. Part of the work is an introduction to the physical and chemical parameters of water, as well as optical methods, which include photometry, spectrophotometry and colorimetry, and an introduction to regression analysis. These methods and analysis are followed by a practical part by measuring pH, nitrate and water hardness using a spectrophotometer and an AS7262 visible light sensor with a SparkFun development board. At the end of the work there is a comparison of absorption spectra, calibration curves and linear regression parameters of both methods.

Comparison of chemical oxygen demand and total organic carbon for the determination of organic carbon content in water
Tobolková, Eva ; Načeradská, Jana (advisor) ; Novotná, Kateřina (referee)
Chemical oxygen demand (COD) and total organic carbon (TOC) are determinations that are used to summarize the organic pollution of waters. However, these determinations do not provide the same information about the content of organic substances in waters. COD is an oxidation method and different substances react differently to this determination. TOC is more accurate as an indicator of organic pollution. Therefore, their ratio will be different for waters with different compositions. This work focuses on evaluating the advantages and disadvantages of determining COD and TOC and comparing their ratios in waters with different compositions. The goal of the work was also to determine whether it is appropriate to introduce coefficients for converting COD and TOC for different types of water. Based on the literature search, it was found that the determination of TOC provides more accurate information on the content of organic pollution in all types of water. The determination of COD by the dichromate method is important for wastewater, mainly due to the estimation of the proportion of degradable pollution. The COD/TOC ratio for municipal waters is relatively stable due to their similar composition, and the determination of the conversion coefficient is possible. This does not apply to industrial...

Comparison of mechanical and biological wastewater treatment plants in terms of financial costs and environmental impact
Winkler, Ondřej ; Výskala, Miloslav (referee) ; Aigel, Petr (advisor)
The aim of this bachelor thesis is to analyse and compare the operating costs and quality of water discharged at mechanical-biological and root wastewater treatment plants. In the first part, the bachelor thesis deals with theoretical knowledge in the field of wastewater treatment. There is legislation related to WWTPs, types, quantities, and transport of wastewater, it also describes the process and technology of water treatment and, finally, the management of waste generated during treatment and its treatment. The following chapters are devoted to economic indicators of wastewater treatment plants as well as pollution indicators. This part forms the transition between the theoretical and practical part of the bachelor thesis. We will learn here what are the costs of operating the treatment plant and how these costs will be reflected in the calculation of sewerage. We will also learn here which pollution indicators are measured as part of the quality of wastewater discharged from the WWTP. In the following part, the bachelor's thesis deals with the analysis and comparison of the already mentioned costs of operation and quality of discharged water at different types of wastewater treatment plants. The analysis was performed at four root and six mechanical-biological wastewater treatment plants in a total of four districts. The conclusion of the bachelor thesis belongs to the global comparison within the Czech Republic and the evaluation of the goals of the bachelor thesis.

Removal of lead and other metals from water
Šopíková, Lucie ; Vybíralová, Pavla (referee) ; Biela, Renata (advisor)
This work covers the topic of metals and semimetals in water. It is divided into three parts. First, each element is characterized by its properties and behavior in water. Incidence in the environment, utilization and effects of intake on human body are described for each element. Second, means of elimination from water are introduced. Different chemical, mechanical and biological methods are discussed. In greater detail, precipitate method, cementation, electrochemical processes, sorption and biosorption are reviewed. Third, hands-on filtration experiment of polluted water with the help of different filtration materials is included. This experiment was done in a laboratory belonging to the Institute of Municipal Water Management, Faculty of Civil Engineering, Brno University of Technology.
