Volatile organic compounds are mostly found in the water as contaminants of human origin. Theoretical part of the thesis is focused on characteristic and occurence of volatile compounds. At the same time it also deals with possibilities of their qualification and quantification. Extensive description have been focused to static head-space technique combine with solid phase microextraction. The objection of the experimental part was gaining experience with operating the device/instrument used for measuring. After locality selection could begin sampling and their analysis.

The diploma thesis deals with treatment of surface waters containing humic substances. The most often used method of surface water treatment is coagulation with subsequent separation of aggregates. In this study, only perikinetic coagulation phase was studied. It is the phase when aggregates are formed by the Brownian motion only, i.e. without mixing. Separation of the formed aggregates was made by centrifugation. Coagulation tests were made under the laboratory conditions with model humic water. Humic substances were added from a concentrate, which was taken from a natural peatbog. The influence of temperature on the coagulation process was studied, ranging from 5 to 22 °C. Chitosan (natural biopolymer) was used as coagulant. In present, it is not used in Czech water treatment practice yet. No effect of temperature was observed when chitosan was used as coagulant. Influence of temperature was also studied with the use of aluminium and ferrous sulphates, which are used in common praxis as coagulation reagents. Influence of the temperature was observed and is in agreement with previously reported data of pilot-plant experiments by other researchers. Spectroscopic methods were used to evaluate the coagulation efficiency and determine residual concentration of aluminium and ferrous coagulant. Chemical oxygen demand (COD) was determined for optimal doses. At first, coagulation tests were made under the laboratory temperature. This tests determined optimal aggregation time and optimal coagulant dose under low temperature. Afterwards, all coagulants used were compared at given temperatures.

In the first part of this thesis the methodic of lab trial was studied, which will be useful for studying adsorption of natural organic matter by activated carbon. As an optimal method of testing adsorption characters jar testing was chosen. Again as an indicator of organic contamination, it was decided to use permanganate chemical oxygen demand (in Czech CHSKMn) will be used. In the second part of this thesis the adsorption characters of eight types of granular activated carbon were studied. Those granular activated carbon came from two world produces, from company NORIT five type of granular activated carbon were tested: NORIT GAC 1020, NORIT PK 1-3, NORIT GAC 1240, NORIT ROW 0.8 SUPRA a TOD NORIT ROX 0.8 and from company Chemviron Carbon three types of granular activated carbon were tested: F100 FE11120A, F400 FE11210A a TL830 FE2028B. Batch kinetic tests of natural organic matter adsorption were conducted with all types of granular activated carbon at first. For description of sorption not only the batch kinetic tests and duration needed for setting equilibrium were observed, but also the process decreasing of concentration of natural organic matters to the value of equilibrium concentration known as adsorption equilibrium was followed.

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.

This master´s thesis deals with the possibilities of innovation process water treatment. Specifically, to explore the use of sodium water glass and nanoiron in removing heavy metals from raw water at the drinking water treatment. For the comparison was used traditionally used coagulant, particularly liquid aluminum sulfate. The introductory part deals with the possibility of modifying the surface water during the treatment process such water into potable water. This chapter is a description of the quality of raw water used, then the description of currently used separation processes. Furthermore, they are described and commonly used types of treatment plants. Conclusion The introductory section deals with traditional coagulants and form a suspension. Another part of this master´s thesis has been devoted to the possibilities of innovation in the treatment of raw waters as drinking water, describes the options and features of the use of water glass and nanoiron. The following section describes the experimental part of this thesis. It is followed by the experimental results. The last chapter summarizes the acquired knowledge and commented on the measured values of the experimental part. This work also shows several specific projects using innovative technologies presented.

This thesis describes possibilities removal of iron and manganese from the water. The first part of the thesis describes the sources and forms of iron and manganese in water, the health limits and possibilities removal of iron and manganese from the water. Contact filtration and materials used for contact removing of iron and manganese are described in more detail. The second part describes using materials Birm, Greensand and Semidol in practise. There i also described the experimental removing of iron and manganese by these three materials.

The aim of the thesis is Kateřinice water treatment plant technical condition assessment and ascertained malfunctions elimination project. The documentation is enclosed. Essential part of the thesis is concerned with calculations and variant solutions of the object reconstruction and water treatment technology. Technical drawings of the water treatment plant are included. All the data was processed in accordance with valid laws and standards. The water treatment plant will be restored to its functional state on the grounds of the designed solution.Therefore permanent high quality of drinking water will be guaranteed for the inhabitants of Kateřinice.

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.

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.
