The floating islands technology for wastewater treatment
Kohut, Rafael ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
Importance of proper water treatment is well described in the European Water Charter. However, considering incessant population growth and role of water as a key raw material in all industries and agriculture, we can say that its availability and quality is endangered. To improve the quality of water and water ecosystems, the strategy of renewal of wetlends is being presented as relevant. Except for natural wetlands there is also a variety of artificial ones, which are trying to simulate because of their treatment conditions. This is one of the main reasons why application of floating wetlands raises a great interest nowadays. In at least seventeen countries all around the world the surveys were conducted to define efficiency of this method for purifying of waters. Despite these efforts, the assesment of the reliable evaluations still remains a large research gap. The purpose of this thesis is to present and describe results of a month´s measurements of efficiency of usage of floating wetlands for refinig of wastewater stabilization pond of root zone wastewater treatment plant in the climatic conditions of the Czech Republic.

Treated Waste Water Irrigation
Kohut, Rafael ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis deals with the issue of simulation of treated wastewater irrigation by the HYDRUS 2D software. The first part of the thesis is designed as a theoretical research of academic information and knowledge. It aims at introducing the issue of treated wastewater utilization for the purpose of the irrigation. Furthermore it provides basic theoretical information on numeric simulation of the dissolved materials motion and transport in the soil. The last chapter of the theoretical part describes the calibration of the simulation by the HYDRUS 2D software. The second part of the thesis is devoted to the formation of filtration columns placed in the chosen site of the root zone wastewater plant. Within the filtration columns the automatic irrigation was formed and set off. Measuring of humidity in filtration columns was taking place for 81 days as well as the water sampling after the flow through the soil horizons. On the grounds of the measuring results the calibration of numeric simulation was carried out by the HYDRUS 2D software. The last part of the thesis presents the applications through the extending and alternation of the modelled setting. The main aim of the thesis is to calibrate the model and propose a general solution to advancement at realization of irrigation details when using the treated wastewater for the purpose of irrigation.
