Membrane Bioreactor Technology for Greywater Treatment in the Laboratory and Real Conditions
Velikovská, Kristýna
Wastewater reuse is one of the signs discussed topics leading to sustainable water management. Separation and recycling of wastewater already at the level of households and other residential or operational buildings could be considered as a key approach of modern conceptual development concerning the perception of waste as a resource. The aim of this paper is to present and compare the results from testing membrane technology (membrane bioreactor, MBR) for greywater treatment in the laboratory and real conditions water reuse at the household level.

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.

Reuse of wastewater in multifunctional buldings
Skřička, Jakub ; Úterský, Michal (referee) ; Hlavínek, Petr (advisor)
This diploma thesis presents reader with current knowledge in the field of gray wastewater reuse. The theoretical part describes the current state of water in the world, thus characterizes wastewater and describes its treatment. Further, this section describes the possibility of obtaining thermal energy from wastewater. At the end of the theoretical part, the reader is presented with some existing buildings in the Czech Republic that use the wastewater re-use technology system. In the following practical part, all the knowledge from the theoretical part are applied for a concrete project of construction of a graywater re-use technology system in the area of Vlněna in Brno city.

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.

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.

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.
