Options removal of micropollutants with water treatment processes
Zdražilová, Alena ; Bogáňová, Ida (referee) ; Biela, Renata (advisor)
This diploma thesis is engaged in problems of micropollutants removal by water treatment process. The first part aims to define single micropollutants, possibilities of their removal in laboratory and micropollutants removal on water treatment plant. In the second part, there is data evaluation of water analyses on factual water treatment plant. Also there is description and evaluation of experiment, which aims to pesticide removal from river by using filtration across granulated active carbon.

Possibilities of removing metals from drinking water sources by water treatment processes
Marzinová, Kristýna ; Látal,, Milan (referee) ; Biela, Renata (advisor)
In my diploma thesis I focused on the issue of metals, their occurrence in drinking water sources in the Czech Republic and the possibility of their removal by water supply processes. Heavy metals degrade the quality of water resources, so more complex water treatment technologies are needed. The first part describes the metals, their properties, their significance and occurrence in water, then the possibility of removing metals using water supply processes. In the practical part of the diploma thesis I performed a laboratory experiment to remove iron, manganese and nickel by adsorption on selected filter materials, which are Filtrasorb F100, Filtrasorb F 400, Bayoxide E33 and GEH. The experiment was used to compare the effectiveness of selected sorption materials.

Evaluation of the benefits of reconstruction at the water treatment plant
Zikudová, Markéta ; Nováková, Jana (referee) ; Kučera, Tomáš (advisor)
The subject of this bachelor thesis is a comparison and evaluation of the condition of the Nudvojovice water treatment plant before and after the reconstruction. The bachelor thesis gradually describes the basic concepts and general principles of treatment of raw water for drinking water. Specifically, the work describes the methods of raw water collection, technologies used in treatment plants, water quality indicators and types of water treatment plants. The work also describes in detail the Nudvojovice water treatment plant before reconstruction, which took place in 2018 and after. The work is mainly focused on the collection of raw water, changes in treatment technology and the quality of raw and treated water. The work also presents other than implemented solutions for drinking water treatment and then compares the status of the original and reconstructed water treatment plant in various respects.

Evaluation of the efficiency of a pilot ultrafiltration unit
Zelinová, Kristína ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
The first part of this bachelor thesis deals with a summary of current knowledge about membrane technologies and their application in drinking water treatment. There are listed different types of membranes and classification of membrane processes. Further on, there are defined operation processes that are related to their use in water treatment plants and there are also listed some of the water treatment plants in the Czech republic, where these technologies were or are still being used. In the second part if this thesis, there is described a situation in a village Poniky, in Slovak republic, which suffers from seasonally increased turbidity on one of their drinking water sources. The owner of the water supply system has an intention of treating this water quality problem by using a membrane technology. This thesis presents and evaluates results from the first membrane tests executed on the affected water source.

Monitoring drug removal efficiency from water by selected adsorbents
Moravčíková, Světlana ; Talašová, Lucie (referee) ; Biela, Renata (advisor)
This diploma thesis deals with the efficiency of removal of pharmaceuticals from drinking water by selected adsorption materials. The first part describes sources of pharmaceuticals in drinking water and possible ways of contaminating water by pharmaceuticals. Subsequently, the pharmaceuticals most commonly found in the environment - nonsteroidal anti-inflammatory drugs, antibiotics, psychiatric drugs and sex hormones - are described in more detail. Next, the thesis describes the processes used for removal of pharmaceuticals. These are activated carbon adsorption, membrane processes and advanced oxidation processes. The last chapter of the theoretical part of the thesis deals with water treatment plants, where the technologies for removing drugs are already in operation. In the practical part of this thesis an experiment was performed and evaluated, for a purpose of comparing the efficiency of selected sorption materials in the removal of diclofenac from water. Filtrasorb F100, Bayoxide E33 and GEH were used.

Evaluation of the impact of technical and technological adjustments to the water treatment plant on the quality of treated water
Jedličková, Ivana ; Látal,, Milan (referee) ; Kučera, Tomáš (advisor)
The subject of this bachelor thesis is the evaluation of sequential technical and technological changes of water collection and modification at a specific water treatment facility – the water treatment facility in Ivančice. The first part of the thesis explains the basic terminology such as technological processes of the water treatment plant, types of water treatment facilities, the range of different types of water based on its quality and technologies that can be found at the water treatment plant in Ivančice. The next two chapters describe the water treatment process before and after intensification. The primary focus is on raw water collection, the quality of both raw and treated water, and the water treatment technology. The last part of the paper offers multiple comparisons of the original and renovated facility and recommendations for improving the operations of the renovated water treatment facility. The final evaluation was carried out based on the information collected mainly by visiting the facility in person, and other sources.

Drinking water treatment plant Koryčany - used technology and their changes from the actuation to nowadays
Konečná, Veronika ; Mergl, Václav (referee) ; Mega, Jaroslav (advisor)
Bachelor's thesis describes the problems of drinking water treatment with regard to specific technology used at Koryčany drinking water treatment plant which covers about 13 per cent of drinking water production in Hodonín district and supplies about 20 thousand people. Technology used at Koryčany drinking water treatment plant and their changes over the years of its existence (from 1959 when the original project was developed until nowadays) were depicted using archives and other available sources. The drinking water treatment plant was designed originally as four-stage (partial decarbonization, clarification, filtration, dechlorination). Decarbonization was left out before completion and dechlorination was skipped during reconstruction in 1971. Since then there were two more reconstructions (in 1991-1993 and 1998-1999) but the technology remained two-stage (clarification, filtration) so far.

Comparison of various modifications of coagulating tests
Vymazalová, Kamila ; Dolejš, Petr (referee) ; Mega, Jaroslav (advisor)
In the theoretical part of diploma thesis is elaboreted literary search relating to problems with using of various modifications of coagulation tests. The experimental part of diploma thesis is focused on comparison of three types of coagulation tests during treatment of model water with increased content of humic matter. Concretly was compared classic jar test, modified jar test and centrifugation test. As a coagulant was used ferric sulphate. The efficiency of treatment was tested under various conditions (temperature, time of fast mixing and intensity of slow mixing). Information capability of results was evalueted on the basis of absorbance by 254 nm and 387 nm, residual concentration of iron and dichromate value. Obtained results were numerically processed and they are presented in the form of tables and graphs.
