The subject of this thesis is make analysis water system in the pavilion of reptiles in the Zoo Brno, with an emphasis on environmental sustainability, local fauna and flora. It is propose specific technical and technological resolutions to reduce the economic and energy performance of the pavilion. The design primarily needed to respect the needs of the animals, but also high aesthetic and educational function of the pavilion.

Thesis: Sanitation installation in a hotel with health resort The unit has 6 floors, it is partly with a cellar. The 1st floor is intended for spa purposes, the floors 3-5 serve as the acommodation area and in the 6th floor there is a machine room. The theoretic part is focused on the water problematics, on the type of sewages, including the labeling of their colors, and the following secondary use of the sewages. The next step is the choosing of the appropriate obtion. The project concerns the sanitation installation in a hotel with health resort.

This thesis solves sanitary equipment installation and design of distribution of gray water in the hotel. Designed building has three floors and basement. On the first floor there are a restaurant, bar, conservatory, sanitary facilities and kitchen facilities. In the second and third floor are rooms for guests. In the basement there are storages, laundry room, engine room and other rooms, which are important for operation. The theoretical part is focused on familiarization with the theme of gray water, their division and possibilities. The practical part of applied knowledge on the subject at. The work also includes the calculation of return on this technological system.

The main topic of the work is water. Intermedial installation consisting of objects and video.

Libya as many other regions under arid climates suffer from inadequate water resources to cover all the needs of this rapidly developing country. Increasing water amounts for population supply, agricultural irrigation and use for industry are needed. As groundwater is the main water source in the country it represents a natural resource of the highest economic and social importance. Conceptual and numerical models were implemented in a regional scale to show how the natural situation has been changed after heavy groundwater abstraction having occurred in the last decades in the northwestern part of Libya. Results of the numerical model indicated that the current zones of depression in piezometric surface could have been caused by smaller withdrawn amounts than previously estimated. Indicated differences in assessed withdrawn groundwater volumes seem to be quite high and might influence considerably the future possibilities of groundwater use in the study region. 6

The main aim of the thesis is to propose or initiate how the technology of sewage treatment in village Dyjákovičky can be modified or upgraded. Special attention is paid to the legislative aspects and the efficiency and conditions of treated wastewater (effluent) that goes back to the recipient. Integral part of the thesis is classification of types of wastewaters and most frequent technologies used for wastewater treatment in small or medium size wastewater treatment plants using specific methods of mechanical pretreatment and biological processes. The technology equipment used in Dyjákovičky is described into details. In response to main aim of the thesis, the actual state of the equipment as well as the state of the whole wastewater plant are assessed in order to identify the main risks and threats. Identification of risks and threats also reflects the presumed demographic and legislative development of implementation of technological and operational measures to improve the parameters of treated water into the recipient.

The thesis is focused on measuring of water quality and phytotoxicity of sediments. In first part is described legislation related with water and ponds and also is determined the terms associated with this topic. Furthermore is characterized location and described places of taking samples. Samples were taken in quarterly periods and then evaluated in laboratory of Mendel university Department of Applied and Landscape Ecology. In following part are specified procedures of evaluation taken samples and evaluation results monitored parameters (amount of dissolved oxygen, pH, temperature, conducti-vity, chemical oxygen demand, quantity of nitrates, nitrogen and phosphor). Phytotoxicity was evaluated by test phytotoxicity through the Phytotoxkit.

The diploma thesis is focused mainly on water quality and water protection on Vranov Water Reservoir. The Vranov Dam is located on the Dyje River in the Znojmo District of the South Moravian Region, near the town of Vranov nad Dyjí. The first part of my work – literary research – is focused on the water pollution problem. Preliminary chapters deal with the industrial and agricultural pollution – pesticides. We discuss the issue of eutrophication and related aspects - nitrogen, phosphorus and Nitrate Directive. Moreover we deal with acidification, acid rain and the presence of drugs in the waters. The following chapter "Characteristics of the area of interest" describes the catchment area and the Vranov waterworks. In the practical part we work with analyzes obtained from Vodárenská akciová společnost, a. s. and Povodí Moravy, s. p. Selected indicators of water quality are evaluated and graphically depicted. We compare the results with the relevant orders and with the expert articles in the discussion, elaborate a risk analysis and evaluate the existing protective measures.

The thesis deals with the analysis of medicaments residues in sewage sludge specifically a selected group of analgesics. The analgesic residues (ibuprofen) were determined in the taken inflow, outflow and activated sludge samples and subsequently analyzed by SPE extraction and LCMS method. Obtained data are compared with sewage disposal plant in Brno-Modřice. From the obtained results is clear that a smaller sewage disposal plant does not mean the same as a worse sewage disposal plant. The analyzed data are related to the sewage disposal plant depending on the number of population equivalents. In the practical part of my thesis are introduced especially two sewages disposal plant, namely the waste sewages disposal plant in Třebíč and in Čáslavice, where the possible percentage degradability of medicaments in wastewater is determined according to the obtained laboratory results.

This thesis deals with measuring of water quality and phytotoxicity of sediments in the Opatovice reservoir which is situated in Vyškov, in the South Moravian Region. The first part of thesis is literary research and it is focused on related legislation, types of water, protect of water, reservoirs of water, sediments, water quality and ekotoxikology. The second part is focused on Opatovice reservoir. There is a destription of nature conditions of reservoir and its technical specifications. Last part is evaluation of selected indicators of water quality and evaluation of phytotoxicity of a sediment sample. The results of thesis shows that Opatovice reservoir has not problems with water quality and its sediment is not phytotoxic.
