Technology of wastewater reuse
Velikovská, Kristýna ; Raček,, Jakub (referee) ; Hlavínek, Petr (advisor)
This diploma thesis presents the knowledge of wastewater reuse. The theoretical part of the thesis describes types of wastewater (greywater, brownwater, and yellow-water) and their characteristics. Further, the theoretical part describes the possibilities of re-use of wastewater as a source of water in detail, including treatment technology, and the heat recuperation from wastewater. The practical part of the thesis uses gained knowledge for designing a greywater treatment and heat recovery technology of grey water in an apartment complex.

Proposal for the use of gray water in the swimming area "Kraví hora" with a view to completion of the wellness center
Běloušková, Pavla ; Plotěný, Karel (referee) ; Biela, Renata (advisor)
Greywater is the leftover water from baths, showers, hand basins and washing machines only, what implies that it is free of faeces and urine. Greywater can be recycled as processing water (whitewater) for toilet and/or urinal flushing or landscape irrigation. Energy recovery from greywater looks also very promising. The subject of this thesis is short research on the issue of the use of greywater in the first part, the following chapter provides examples of the use of greywater in practice. Practical part of thesis provides suggestion of use of greywater and their heat potential in swimming area Kraví hora with regard to completion of wellness centre. This part also includes economical analysis of suggested recycling.

Sanitary technical installations and gas pipeline in the hotel
Ševčík, Jan ; Wierzbická, Helena (referee) ; Vaščáková, Alena (advisor)
Diploma thesis deals with design of sanitary and gas instalation in hotel building. It is hotel with four floors and basement. Theteoretical part is focused on grey water treatment systems and possibility of their use in the building. The Computational part and project includes design of sanitary and stormwater sewer, water supply system, gas installations a their service pipes to current utility lines.

Plumbing Systems with Low Water and Energy Consumption
Nikrmajer, Vojtěch ; Vrána, Jakub (referee) ; Bárta, Ladislav (advisor)
The thesis deals with energy-saving plumbing systems. It is divided into three parts: task analysis, applications theme on the building and experiment. In the first part are described the possibilities of saving water and energy in the plumbing systems. The second part contains a comparison of some variants of saving solution water supply system and sanitary drainage system at the hotel. Part of the experiment investigates the water consumption for washing hands in addiction: the pressure in the water supply system and the type of mixing valves.

Possibilities of saving measures in swimming pool operations
Litschmann, Patrik ; Pivoda,, Bohuslav (referee) ; Biela, Renata (advisor)
The diploma thesis deals with the current knowledge in the field of saving measures in swimming pool services. The theoretical part describes the typology of swimming pools and subsequently deals with the technological aspect, including heat management. Furthermore, the theoretical part describes in detail the possibilities of saving measures in public swimming pool operations, especially in sanitary facilities, including reuse of wastewater from showers as a water source, or heat recovery from wastewater. The knowledge from the theoretical section is then applied in the practical part, where saving measures are proposed on the public swimming pool.

Methodology of use greywater in the selected objects
Raček, Jakub ; Pollert,, Jaroslav (referee) ; Stanko,, Štefan (referee) ; Raclavský, Jaroslav (advisor)
The concept of reusing wastewater in buildings has recently become more important. This is due to change in climatic conditions and reduction of the yield of water resources. Greywater can broadly be defined as not extremely polluted wastewater coming from basins, showers, baths, kitchen sinks and washing machines. The concept based on the use of alternative rate sources wouldn't need same strict parameters as drinking water. Dissertation engage in collecting greywater from basins, showers and wash machines separately from the other more polluted domestic wastewater at the dorms, the laundry machines, the hotels, detached houses, the swimming pools, the office buildings and other buildings. The research showed that membrane filtration meets all needed parameters of water quality and can be used in house systems where we use cleansed white water to flush toilets, watering garden or grass areas. There is still a lack of experience and documentation for such system of operation in our country. Systems of use of greywater in selected objects are detaily solved in my dissertation directed at system proposal.

Rainwater infiltration
Kračman, Martin ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor´s thesis is to define legislative options of infiltration, retention and drainage of rainwater for household in Czech republic. Thesis describes not only rainwater, but also waste water, the quality and usage of them both. Furthermore, the?amount of usable grey water in household is defined. Then the systems for retention waste water and rainwater are desribed as well as technical principles of their design and purification of rainwater. In the final part od this thesis, the systems for usage of?rainwater and grey water are designed. Finally, the designed systems are evaluated and their feasibility is assessed.

Possibilities of using gray waters
Bogáňová, Ida Antonie ; Raclavský,, Jaroslav (referee) ; Biela, Renata (advisor)
Greywater is waste water from washbasins, showers, baths, kitchen sinks, dishwashers and washing machines. This can be treated to gain so-called white water, which can for example be used for flushing toilets and urinals, watering greenery or for cleaning. The subject of this diploma thesis is to state the possibilities for utilisation of greywater. In the first part of this thesis, research will be elaborated on the given topic. In the following chapters, I would like to state examples of the possibilities for utilisation of greywater. The practical part should consist of design of a system for treatment of greywater in a specific building.

Greywater Treatment by Membrane and Sand Filtration
Velikovská, Kristýna
Greywater reuse is a significant part of urban wastewater with low values of physical, chemical and microbiological pollution indicators. Therefore, reusing greywater is an effective approach of sustainable water management. This paper deals with greywater treatment membrane methods leading to reusing greywater, presenting obtained values of testing sand filtration and microfiltration and ultrafiltration membrane modules.
