Drainage of waste water from the industrial area in Hulin city
Dohnal, Radek ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
The subject of this thesis is to implement the passport of sewer system installation, technical assessment and evaluation of the technical condition of the entire sewer network in the industrial area, along with focus and plotting the current leadership of the sewerage system. It was also developed a hydraulic model of the entire solution sewer system. In the second part of the study is a proposal for an appropriate treatment system of wastewater. It was also developed a hydraulic model of the entire solution sewer system. In the second part of the study is a proposal for an appropriate treatment system of wastewater. In conclusion there is a financial assessment and comparison of different variants cleaning system in terms of investment and operating costs.

Contamination of environment of musk compounds
Tobková, Lenka ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
Synthetic musk compounds are artificial organic substances commonly used as fragrant constituents of personal care products as parfums, cosmetics, detergents, in-house cleaning and washing agents. Given their large area of applications and their ability to be persistent, they leaked into all parts of ecosystem, especially aquatic one. There have been a big focus on studiyng these compounds, their properties and fate in the different parts of ecosystems in the last years. The aim of master's thesis was carry out the determination of five representatives (habanolide, exaltolide, ambrettolide, musk MC4 and ethylene brassylate) of macrocyclic musk compounds in waste water samples from influent and effluent of three water treatment plants (WWTP Brno-Modřice, WWTP Lednice and WWTP Mikulov). One of the main tasks was to perform a method optimisation for the determination of selected musk compounds in waste water and evaluation and interpretation of the results. Solid phase microextraction (SPME) technique was used for the extraction of analytes, consequently gas chromatography-mass spectrometry was used for analysis of selected analytes. Following evaluation the removal efficiency of musk compounds in the waste water treatment plant was assessed.

Sludge pretreatment and its further utilization
Němec, Jan ; Dlabaja, Tomáš (referee) ; Elsässer, Thomas (advisor)
The thesis deals with methods of pre-treatment (disintegration) of sewage sludge, which offers an opportunity for better operation of a waste water treatment plant. The introduction is aimed at sewage water and sludge dividing, and then at their characteristics. In this thesis a current state of sludge disposal within the reference to the legislature and how to divide the methods of disintegration is also marked. Afterwards a description of selected methods of sludge disintegration, their comparison and the applicability of thermal disintegration to pasteurization of sewage sludge is included.

Study of sewerage and wastewater disposal
Dvorský, Petr ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
This thesis deals with the study of the sewerage network in the village of Pavlovice u Přerova. Its main objective is to accomplish the passportization of the sewer network in the village, including the inspection of the waste water treatment plants. Based on the results of the passport, a hydraulic analysis of the sewer network was performed. The technical and operational state of the selected sections and the objects on the sewer network was evaluated. The draft measures for bad sections of the sewerage network and for the waste water treatment plants were taken on the basis of the evaluation. In the next part of the thesis, there were chosen methods of rehabilitation of the sewer network and the design of new waste water treatment plants. The proposed variants are also economically evaluated and compared. The thesis is complemented by the situation of the sewer network as a result of the passportization and also with the hydrotechnical situation.

The study of selected sewer network in an urbanized catchment
Korytář, Ivo ; Habr,, Vladimír (referee) ; Raclavský, Jaroslav (advisor)
This paper deals the case study of the chosen sewer system in the village Starý Mateřov. The study solves passportization of sewer, what is the base for creating technical condition mainly for three selected sections. According to the results from the technical conditions of the three selected sections were suggested suitable options of redevelopment. The options are compared in financial way. The last chapter suggests two possibilities how to deal with the sewage. The first option consists of the transferring waste water to the waste water treatment plant in Pardubice - Semtín. The second option suggests building a new waste water treatment plant in Starý Mateřov. The options are compared in financial way.

Effects of Municipal Wastewater Treatment Plant at Lopac Sinkhole Cave System
Ondruš, Martin ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the northern area of Moravský kras protected landscape, where the impact of WWTP Ostrov u Macochy on a cave system Lopačské propadání was studied. As a part of this study a half-year monitoring was carried out, which consisted of water sampling every two weeks. In total, 13 water samples were taken from 7 sampling points. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, COD, BOD, N-NH4+, N-NO2-, N-NO3-, NKi and total phosphorus were determined in the samples. The change of parameters in time on the sampling points and further along the flow of the river was evaluated from the measured values. The outflow values from waste water treatment plants were compared with the emission limits for surface waters and the values of river water parameters were compared with the environmental quality standards. It wasn’t proven that the outflow from the observed waste water treatment plant is negatively influencing the water stream. The most serious problems are: -The WWTP was designed for treatment of sewage from Ostrov u Macochy, which involved separate sanitary and storm sewers. After finishing the WWTP, a uniform sewer was built. -High concentration of total phosphorus on the outflow from WWTP. -Poor quality of Lopač brook water already before the outflow vent from WWTP.
