Comprehensive water management in a family house without connection to the wastewater disposal system
Plhák, Jiří ; Kriška-Dunajský, Michal (referee) ; Hyánková, Eva (advisor)
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.

All-embracing water management in a residential object in a Pařezov village
Királ, Martin ; Hubačíková,, Věra (referee) ; Hyánková, Eva (advisor)
This diploma thesis deals with sound water management and is divided into theoretical and practical part. The theoretical part is divided into three main chapters. The first part focuses on rainwater, its quality characteristics and utilization. The second chapter focuses on the management of waste water, its properties, the amount of waste water and natural ways of wastewater treatment. The last chapter is devoted to the gray waters and their utilization. The practical part focuses on the study of the draft comprehensive management of sewage and rainwater in the village Pařezov district Domažlice. It focuses on wastewater treatment using constructed wetlands, using rainwater for irrigation and infiltration of the remaining water.

Monitoring and evaluation the first year of operation of the vertical flow filter in constructed wetland
Vláčil, Lukáš ; Kriška-Dunajský, Michal (referee) ; Pumprlová Němcová, Miroslava (advisor)
This Bachelor’s thesis evaluates the one-year operation of a new type of vertical filter bed in the constructed wetland in Dražovice. This evaluation will be used to compare the efficiency of treatment – ammonia nitrogen removal – in the Dražovice constructed wetland before reconstruction (the installation of the vertical filter) and after the reconstruction. The introductory part deals with the theoretical research summarizing expert information and learnings, in order to provide insight into the issue of constructed wetlands and vertical filters in particular. Individual technological installations are described and the operating principle of constructed wetland technology is explained. The practical part of the thesis describes and evaluates the treatment efficiency of the vertical filter installed in the Dražovice constructed wetland in 2016. The results evaluation focuses on two indicators: N-NH4+ and CODCr in the period between January 2017 and May 2018.

Technology to increase hydraulic conductivity of constructed wetlands
Pobořil, Jan ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
Constructed wetlands are one of alternative solution wastewater treatment. Compared to conventional wastewater plants have many advantages. For example it´s technology saving construction, low operating costs, cleavability diluted wastewater and little or no need for electrical power. There are many publications dealing with Natural Ways wastewater treatment or even constructed wetlands. I decided to look for a thesis on one of the key processes – clogging bed media. The thesis is focused on ways to prevent clogging of bed media, mitigate the consequences and technology to increase hydraulic conductivity of constructed wetlands. The main test method is improving drainage parameters using pulsed filling and emptying of the bed media. This method is a very effective way to achieve quality requirements for effluent water from the treatment plant. Another test method is based on the injection of air into the media bed and sludge extraction using a specially modified industrial vacuum cleaner or pump.

Occurence of organic pollutants in constructed wetlands
KUTHANOVÁ, Eliška
Constructed wetlands are wetlands designed to improve the quality of water. In this work, four representatives of typical organic pollutants in Constructed wetlands are studied : DEET, cotinine, coprostanol and galaxolide as the representatives of insecticide, alkaloid,faecal sterol and musk compound respectively. Moreover three different types of extraction techniques : aqueous two phase extraction (ATPE), liquid-liquid extraction (LLE) and stir bar sorptive extraction (SBSE) - are investigated with respect to the overall extraction yield regarding the above mentioned compounds.
