Kinetics of photocatalytic and electrophotocatalytic degradation of swimming pool water model pollutants
Morávková, Eva ; Cihlář, Jaroslav (referee) ; Veselý, Michal (advisor)
This diploma thesis deals with the coating and printing of thin layers based on nanoparticles of titanium dioxide and organosilica binder on various substrates. The influence of the ratio of the both components on the activity of the prepared immobilized layers was studied. Five compositions with different ratios of TiO2 and binder were prepared. The work focuses mainly on the study of photocatalytic and photoelectrocatalytic properties of prepared layers. It was also important to characterize the mechanical properties of the layer such as hardness or adhesion. Both photocatalytic and photoelectrocatalytic activity were determined by monitoring the degradation of the model pollutants in aqueous solutions. The dye Acid Orange 7 and UV filter 2-hydroxy-4-methoxybenzophenone were used in conjunction with UV/VIS spectroscopy or high performance liquid chromatography techniques. Both photocatalytic and photoelectrocatalytic activity were expressed using kinetic characteristics.

The study of the reconstruction of the pool water treatment plant of the summer swimming pool Břeclav
Urban, Jaromír ; Látal,, Milan (referee) ; Biela, Renata (advisor)
The subject of the diploma thesis is to introduce the problems of communal spas, namely the treatment of water for swimming pools. Following is a proposal of reconstruction of the treatment plant for a real, operated area of the summer swimming pool. The thesis is divided into theoretical and practical part. At the beginning of the theoretical part I make research of the history of balneology, the effects of bathing and swimming on the human body, possible resources for spa purposes and hygiene requirements for these waters. I also describe commonly used methods of treatment of swimming pool water. In the practical part I first describe the summer swimming pool in the town of Břeclav. There is a description of the swimming pool, its history and equipment. In the next chapter I present the currently operated technological line. Based on a personal visit, the next chapter evaluates the technical condition of the plant. Based on this evaluation, a new technological line for treatment of swimming pool water of the Břeclav summer swimming pool is proposed.

Use of advanced oxidation processes in pool water treatment
Trávníček, Jakub ; Pivoda, Bohuslav (referee) ; Biela, Renata (advisor)
The research part of the thesis is focused on the use of advanced oxidation processes in the treatment of swimming pool waters. In the first part, the common disinfection technologies that are used domestically and abroad for the treatment of swimming pool waters are described. In the second part, the research focuses on the basic types of advanced oxidation processes used in swimming pool facilities and other similar laboratory-scale technologies with potential for future use in the spa industry. The practical focus of the thesis consists of two parts. In the first part, data from a questionnaire of selected swimming pool facilities in the Czech Republic are processed, which summarizes what technologies are used in the treatment of swimming pool waters in the Czech Republic. The second part consists of a case study that analyses the effect on the quality of treated water before and after the installation of advanced oxidation processes system in the pool recirculation circuit.
