Předkládaná práce se zabývá způsobem ohřevu teplé vody v novém bytovém domě. Teoretická část práce se věnuje jednotlivým způsobům ohřevu teplé vody, popisuje zásobníkové i průtokové způsoby ohřevu, přičemž hlavní důraz je kladen na variantu se zásobníky teplé vody. Hlavním cílem práce je posoudit dvě nabízející se řešení zajištění ohřevu vody ve zvoleném objektu, tedy elektrické zásobníkové ohřevy v jednotlivých bytech a centrální ohřev teplé vody nepřímo napojeným na plynové kotle, a vyhodnotit výhodnější variantu.

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.

Czech Republic is called roof of the Europe, several rivers rise here and many of them flow away and continue to other countries. That's why I find, that’s extremely important to manage out water sources properly and carefully, because for example the weather has a huge impact on our limited sources and can affect them especially in a dry periods. These issues can be improved by finding a use for used water, good storm water management as well as using greywater. In my diploma thesis, I'll be mainly focused on an overall water management in an ordinary family house. It has two parts as theoretical part and practical part. The theoretical part is then split into another three parts. The first part covers a storm water management, the second is about waste water management. The third explains greywater management. In practical part of my diploma thesis, there's my study of not disposing rain water into a drain with other waste water, but making both waters useful. In this my particular subject in village called Plesnice, is projected a waste water treatment plant. Treated water will be accumulate together with rain water. Accumulated water will be used for irrigation. For a waste water treatment is projected a constructed wetland with vertical flow (down flow reed beds) and facility for sludge management. This is example of extensive technology. Irrigation system consists of storage tank with mechanical pre-treatment and pump valve shaft, sprinklers for lawns, drip irrigation decorative surfaces and everything is controlled by a control unit. Thanks to irrigation and rainwater remains in effect, which is important for local microclimate and save drinking water. This study is an example of that in water management is not necessarily a need for global action, but you can start with individuals and individual houses, which in total could have a significant effect on water retention in the landscape and to slow down and reduce the peak flow in rivers.

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.

This work deals with the design, realization and testing of the system for regulating the temperature of the water in an industrial environment using three-way mixing valve. This system can work autonomously, but also can be controlled by a superior control system. Created temperature regulation can be adjusted and controlled by a computer using control software.

The thesis is focused on the design of the new heat source of the existing building. The first part deals with the heat sources and fuels used in the Czech Republic. The second part includes design of three variants of heat sources: gas boilers, cogeneration unit with the electric boilers and cogeneration unit with gas boilers. The individual variations are also evaluated in terms of user comfort, space requirements or economy of operation. The third part includes measurement and evaluation of internal environment of the dining hall.

This diploma thesis deals reconstruction of sanitation installations in an apartment building in Brno. It is a multi-storey building which is intended mainly for living. The theoretical part deals individual ways of preparation hot water in the apartment buildings. The experimental part deals measurement consumption hot water in the apartment building. Calculating and design part contains a proposal of sewerage system, piping system and linking up of the object on present engineering systems. The diploma thesis also focuses on possible options and re-quested specifics. The diploma thesis was arranged in accordance with present-day valid norms and regulations.

Due to eutrophication of aquatic environment, massive growth of algae and cyanobacteria occurs and the seasonal algal bloom is formed. Drinking water treatment plants have to deal with the increased amount of cells as well as organic compounds produced by algae and cyanobacteria (so-called AOM). Moreover, the presence of AOM causes a reduction in the efficiency of coagulation, which is an essential process in drinking water treatment. To increase coagulation efficiency, supportive methods, such as ozone oxidation, are added usually prior to coagulation. While many studies focused on the ozonation of algal and cyanobacterial cells, little is known about the effect of ozonation on AOM. This diploma thesis focused on the evaluation of the effect of ozonation in combination with coagulation on the removal of cellular organic compounds (COM) produced by cyanobacteria Microcystis aeruginosa. The effect of ozonation before or after coagulation on COM removal was investigated. The degradation of microcystins, which are naturally contained in the COM sample, was also monitored. Various ozone doses (1 - 10 mg/L) were tested at three pH values - 5, 7 and 9. Two coagulants were utilized - aluminium sulphate and ferric sulphate. Ozonation removed COM negligibly. However, eliminated microcystins, the degradation...
