Assessment of the effectiveness of filter material DMI-65 on removing metals from water
Konečný, Jiří ; Hrich, Karel (referee) ; Biela, Renata (advisor)
The first chapter of diploma thesis discusses about various water processes which remove metals and metalloids compounds from water. A substantial part is devoted to filter materials, which include a new filter material DMI-65. Comprehensive chapter discribes characteristics, proporties and practical application of filter material DMI-65. The next chapter describes the process of pilot testing of material DMI-65 in the water treatment plant in Ivancice. At the end of the diploma thesis, the laboratory test of filter material DMI-65 is described, including the description of particular metals that are removed from the water and the compresion of the filter materiál DMI-65 with other selected filter materials.

The Research on Regeneration of the Filter Material, used in the Soil Filters and Constructed Wetlands
Burešová, Hana ; Rozkošný,, Miloš (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis consists of two basic parts. The first research part creates an introduction to the root zone wastewater treatment plants. It contains mainly causes of filter environment colmation and its theoretical solution methods, which are further solved in the laboratory. The master’s thesis attempts to find a simple way, which would in future be possible to evaluate the rate of sedimentation of the sludge material, which causes filtration environment colmation. Results of developed methodology will be used in practice by washing colmated filtration material, respectively colmatant separation in sedimentation tank. The thesis focuses to verify the possibility flocculation and mineralization of sludge, which adheres to the surface of the filtration material. The solution lies in the observation of sedimentation rate (after previous dilution) using by the turbidimetric method, based on the beam-column passage through muddy water. The results show that it is not critical ambient temperature, but the time effect of natural mineralization in combination with moisture (dry matter concentration, the amount of water). The present thesis evaluates the possibilities and application method, leading to the natural regeneration of the filtration material exposed to natural climatic conditions.

Filtration of foundry alloys
Šíma, Jakub ; Láník, Boris (referee) ; Tomek, Ladislav (advisor)
Presented bachelor work deals with filtering of casting alloys. This issue is described with focus on the importance of filtration, the requirements placed on filters, a description of the filtering mechanisms, the influence of using filters on the melt flow, types of filters and options include filters in the gating system of casting. The second part contains case studies of the use of ceramic foam filters in foundry and analysis of samples taken from a particular casting.

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.

Water filtration and filter materials
Moravčíková, Světlana ; Talašová, Lucie (referee) ; Biela, Renata (advisor)
This bachelor thesis deals with water filtration. Primarily it describes slow sand filtration and rapid sand filtration. For these types of filtration, the filtration mechanisms, filtration cycles, filtration regeneration and filter layout are described in more detail. In case of the rapid filters, the most commonly used types of drainage systems are summarized. Further there is a brief introduction of diatomite filters and membrane processes used in water industry. The next chapter contains most commonly used filter materials along with their basic properties. Practical part of the thesis focuses on assessment of efficiency of selected filter materials in the removal of pollution.

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.

Specific substances in drinking water sources
Konečný, Jiří ; Kučera, Tomáš (referee) ; Biela, Renata (advisor)
In this bachelor thesis I dealt with specific substances which occures in sources of drinking water and pollutes quality of water. Especially its heavy metal, sulfur compounds, nitrogen, phosphorus and other. In this thesis I deal with possibilities about remove of these substances by using various methods, especially absorption on filter materials. These thesis is focused on using absorption on suitable materials for reduction of concentration arsenic and cadmium in drinking water. In first part I‘ve characterized subtances which occures in the water and outlined a way to remove them. Second part is focused on laboratory observation to efficiency of removing arsenic and cadmium on sorption materials.
