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.

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.

The Sanitary Instalation in Retirement Home
Minář, Lukáš ; Vrána, Jakub (referee) ; Wierzbická, Helena (advisor)
The goal of this diploma thesis is the design of the sanitary installations and gas main in the pension for pensioners. The building has three floors above ground and one underground floor. The building will be covered with a hiped roof. On the first floor there is the technical background of the building, Reception and kitchen with dining room. The basement is located just below the kitchen and serves as a cloakroom for kitchen staff. The building will be designed to use as much non-potable water as possible in the form of rainwater, which will be collected from the roofs. The theoretical part deals with the use of non-potable water as operating water in buildings. The calculation and project part deals with the gravity sewer system, plumbing and gas main in the 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.

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.

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.
