Monitoring the effectiveness of selected adsorbents in removing AOX from water
Rutarová, Natálie ; Kotzurová, Iveta (referee) ; Repková, Martina (advisor)
The diploma thesis was created in cooperation with the company Art Carbon and is focused on monitoring the effectiveness of ART SAND adsorbents in removing AOX from water. The theoretical part provides an overview and basic characteristics of AOX, their impact on the environment and the possibility of their removal. The experimental part is focused on the study of the effectiveness of selected adsorbents with the subsequent use of high performance liquid chromatography (HPLC) with UV detection. Two ART SAND, ASSP50 and ASPP50-X adsorbents, supplied by ArtCarbon, were selected 2,4-dichlorophenol and 2,6-dichlorophenol to monitor adsorption.

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.

Intensification of the wastewater treatment plant in the village Krumsín
Krejsová, Věra ; Ježek, Jiří (referee) ; Hluštík, Petr (advisor)
The task of this master thesis was assessment of the possibility of intensification of biological ponds, which are used for wastewater treatment, and subsequent application of selected systems to the existing wastewater treatment plant in the village Krumsin in the district Prostejov, including economic assessment. In the first part of the master thesis, I worked up the available options for the intensification of biological ponds. In the practical part of the thesis it was prepared a report of the current state of the wastewater treatment plant that serving as a basis for the design of intensification, which is also processed in the practical part. For the proposed variants of intensification was also processed economic assessment.

Methods for separation of ammonia from waste water
Bajzík, Martin ; Touš, Michal (referee) ; Vondra, Marek (advisor)
The bachelor thesis is focused on the methods of separation of Ammonia from the wastewater. The introduction of the thesis defines Ammonia, its characteristics, natural sources, production and utilization of it. The main part of the thesis describes and rates the twelve methods used for the separation of Ammonia from the wastewater. There is a description of a principle, the advantages and disadvantages of the methods in consideration of their utilization in practice, by each technology. In the experimental part of the thesis are described the outcomes of efficiency measurements of the stripping device and their comparison with the results stated in scientific literature. The thesis represents the primar overview and introduction into the theme for laymen and experts, who are unfamiliar with the topic and would like to examine it.

Reuse of treated wastewater in paper and textile industry
Matysíková, Jana ; Vachovec, Roman (referee) ; Hlavínek, Petr (advisor)
This thesis deals with Advanced oxidation processes (AOP) and its aplication for textile wastewaters treatment and reuse. AOP is a modern technology which currently recieves increased attention due to it´s high efficiency in removing resistant and hardly-degradable pollution. Thesis consists of search and practical part. Search part is created by three chapters. First chapter describe briefly wastewater reuse. The second chapter deals with Advanced oxidation processes. AOP principle, AOP division and descriotion is included with the strong focus on the ozonation technology. The third chapter presents the textile industry and its wastewaters. The practical part of this thesis consists of two chapters. Chapter 5 describes testing of textile wastewaters decoloration by ozonation in the selected textile copany and its results. This results are used in chapter 6. Chapter 6 is the study of textile industry treatment and reuse in the selected textile company. This study contains the design of two options for wastewater treatment and reuse in the textile processes.

Optimization of the coagulation procedure for wastewater treatment
Švábová, Martina ; Mravcová, Ludmila (referee) ; Repková, Martina (advisor)
This bachelor thesis deals with the optimization of the determination of the chemical oxygen demand in the test tubes and the optimization of the coagulation process for the external company. COD is one of the basic analysis for all types of water, although there are numerous environmentally-unfriendly agents in case of using a standard version produced. Therefore, an alternative method of using the test tubes was used, the procedure of which has been modified from ČSN ISO 15705 and is now available to the public. The aim was also to optimize the coagulation process in the treatment of wastewater from an industrial paintshop. The minimum dose of coagulating agent occurring in the instructions for usage was disproved and the pH value at which aluminium sulfate as a coagulating agent was proposed.

Alternative water sources on technological process in selected sector of industry
Bártů, Tomáš ; Mifková,, Tatiana (referee) ; Hluštík, Petr (advisor)
The task of the master’s thesis is a study focused on re-use and process wastewater in the company Kostelecké uzeniny a.s. The thesis contains a description of wastewater treatment plants, sewage flow and metabolic load on each water treatment processes. The thesis describes the limit requirements for technological processes within the enterprise. Few variants of the use of alternative water sources for technological processes on the basis of health conditions that has been designed for treating waste water from truck wash were considered in the thesis. Treated waste water is being re-used within the truck wash. Part of the proposal is also economic calculation and evaluation of return on investment.
