Diploma thesis deals with assessing of effectiveness removing pecticides of reconstructed water treatment plant. In the introduction ismade a short research focused on pesticides, their getting into sources of drinking water and possibilities their removing by water supply processes. As part of this work are assessed effectiveness of this processes for removing pesticidal substances on specific water treatment plant and its sources of drinking water. Is made description of technology water treatment plant before and after the reconstruction, measured data of concetration pesticides in the sources and in the output from water treatment plant is processed to the tables and to the graphs. In conclusion are assessed effectiveness of the new technology for removing selected pesticidal substances and their metabolites.

In it´s theoretical part, my master thesis handles selected softwares for wastewater treatment mathematical modelling. It summarizes and compares availible softwares on the market, it´s use, advantages and disadvantages. The practical part deals with an exemplar evaluation of selected wastewater treatment plant according to Czech normative standards and evaluation of the same wastewater treatment plant per mathematical model created in WEST program. The assembly of a wastewater treatment plant model consisted of studies, creation of the layout, insertion of provided data, calibration and model evaluation.

The thesis deals with the design and assessment of all supporting parts of a cast-in-place reinforced concrete sewage tank in a wastewater treatment plant. The thesis includes a technical report, static analysis, drawing documentations, construction process and visualization. The drawing documentation consists of shape and reinforcement drawings of supporting parts.

The diploma thesis is focused on the possibilities of drainage of waste water and its subsequent liquidation in the village of Kamenný Malíkov. The aim of this diploma thesis is the elaboration of variant solutions for drainage of Kamenný Malíkov. Furthermore, the proposal for wastewater treatment, the economic comparison of variants and the recommendation of the unsuitable variant. The diploma thesis deals with the proposal of predominantly gravitational way of drainage of waste water in combination with the pressure, due to incline terrain in the village. Each eventuality has wastewater treatment method designed.

The aim of diploma thesis was finding of the method for the determination of drug residua in sewage sludge from wastewater treatment plant. Selected sulfonamide and diaminopyrimidine antibiotics, which are used in human and veterinary medicine, were selected as target comopounds. They are discharged to the sewer systems together with the urine and faeces and enter the sewage treatment plant, where they are not completely removed. They can be found in treated waste water or in sewage sludge. They can enter to the environment, where they can induce negative effects on organisms in soil and water ecosystem. An optimized method was used for identification and determination of these antibiotics in real samples from the large-scale waste water treatment plant in Brno-Modřice and from the waste water treatment plant situated in the area of Veterinary and Pharmaceutical University Brno. Antibiotics were extracted from sewage sludge by ultrasonic and by pressure solvent extraction (PSE). Waste water and sewage sludge real samples were concentrated and cleaned by solid phase extraction (SPE). For determination these antibiotics high performance liquid chromatography with diode array detector (HPLC - DAD) was used.

The aim of this thesis is to determine the presence of pharmaceuticals in wastewater from several wastewater treatment plants (WWTPs) with different number of equivalent persons and different treatment technologies. Five sulfonamides were chosen for a determination due to their wide usage in human and veterinary medicine practice. The specific compounds are sulfamerazine, sulfamethazine, sulfapyridine, sulfathiazole a sulfamethoxazole. For the determination of those sulfonamides, an UHPLC/DAD analytical method was chosen and optimized. There was also a need for optimization of SPE extraction method, especially a sample volume optimization. 250 mL was chosen as an ideal volume of wastewater sample for SPE. The optimized method was used for determination of sulfonamides in real wastewater samples from WWTP in Podivín, Pohořelice, Hustopeče, Valtice, Lednice and Mikulov. Average concentrations of pharmaceuticals in influent and effluent wastewater samples were in a range of 0,1 – 1 µg/l. The concentration of sulfonamides was mostly found higher in influent samples and lower in effluent samples. It can be said that a partial recovery of sulfonamides on WWTPs was observed.

The possibilities of environmental pollution control are increasing and more advanced wastewater treatment methods are being emphasized, as well as more specific control of contaminants presence in treated waters. That is why it becomes relevant to perform not only chemical analysis but also ecotoxicological bioassays as the means of evaluation of biological effects caused by wastewater discharges to ecosystems. No wastewater treatment plant is able to treat the water perfectly – it can only decrease the pollution level to an acceptable value. Therefore it is important to find out if the treatment process is sufficient to provide a satisfactory decrease of ecotoxicity and also what effects to the organisms in recipient will be caused by wastewater discharges. The thesis is focused on the evaluation of wastewater ecotoxicity. In the experimental part of the thesis, wastewater samples were collected at four wastewater treatment plants in the Czech Republic. At one of them also the sludge samples were taken. The aim was to evaluate the efficiency of wastewater treatment by selected ecotoxicological bioassays. The results have shown that the efficiency of wastewater treatment plants with secondary treatment is sufficient to reduce acute toxic effects to the minimum. Average toxicity removal was over 80 % at three of four evaluated wastewater treatment plants. At the fourth WWTP it was 41 %, however, at this WWTP high efficiency of treatment is not necessary.

The thesis deals with energy demands of wastewater treatment plants. The content is focused on inclusion of membrane modules to the wastewater treatment process. Two possible options of wastewater treatment are compared; first, convetional mechanical-biological wastewater treatment plants with activation and installable tank; on the other hand, plants with activation with membrane module. In the practical part, three possible options of intensification are suggested. In the first part, new mechanisms for the plant are projected, in the second part, the energy demands of this tecnological equipment are treated, and in the last point, the item bugget is processed. The comparison of investment and operating costs is made in the conclusion of the thesis.

The aim of the Diploma Thesis is to propose an assessment of energy-consuming criteria of wastewater treatment plant. We focus on formation of energy questionnaire that is used to evaluate the wastewater treatment plant according to the criteria, and subsequently indicate which processes increase energy consumption. Verification of proposed energy-consuming criteria was carried out with the data of an existing wastewater treatment plant.

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.
