Methods of sewage sludge thermal treatment
Rosendorfová, Lenka ; Pavlas, Martin (referee) ; Houdková, Lucie (advisor)
The first part of this diploma thesis targets in the formation of summary of methods of sewage sludge thermal treatment. Sludge is dangerous material rising from water treatment. Original water pollution is concentrated in sludge. Spectrum of the different methods of sludge disposal is very vast, thermal methods belong to the most advanced ones. Nowadays, legislative rules and regulations make more restrictive, hence sludge disposal is problematic because of economic and ecological view of point. The second part of this diploma thesis is dealt with perspective sludge management at the Central Waste Water Treatment Plant Prague concerning sludge drying and consequent sludge incineration.

Sludge Utilisation from Pulp and Paper Plant
Zemanová, Kateřina ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
The contens of diploma thesis is description of paper and pulp production and analysis of contemporary problems with disposal of sludges rising on industrial waste water treatment plant. Accent is focuses on description of waste water treatment technique, characteristics of rising sludge and the ways of his liquidation in particular plant for pulp production. Fundamental part of this project is evaluation of power and economics balance of current sludge technology in company Biocel Paskov a.s. and suggested sludge management technology. Balances are based on data gained from measurement in laboratory and on data gained from literary research.

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.

Effect of effluent from wastewater treatment plants on karst rivers
Schrimpelová, Kateřina ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
Karst rivers are special type of rivers because of their hydrography conditions. They usually flow from non-karst area and as soon as they reach in to the karst area they disappear underground. There, they flow through cavities until they reach the surface again. 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 central area of CHKO Moravský kras where the impact of two WWTP on a cave system Rudické propadání – Býčí skála is evaluated. As a part of this study a half-year monitoring was carried out, which consisted of water sampling once every two weeks. In total, 13 water samples were taken from 8 sampling points. Also 4 additional one-time samples were taken from the cave system. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, CODCr, BOD, N-NH4+, N-NO2-, N-NO3-, P-PO43- and total phosphorus were determined in the samples. The change of parameters in time and during the flow in the river was observed from the measured values. The balance of pollutants in particular parts of the river was calculated. The outflow values from waste water treatment plants were compared to the emission limits for surface waters and the parameters of rivers were compared to the environmental quality standards. According to the results, it can be observed that the water quality improves after passing through the cavities. It was proven that the outflows from the observed waste water treatment plants are negatively influencing the water streams. The most serious problem is the wash up of sludge from WWTP Rudice and its consequent sedimentation in the river and/or outflow to the Rudické propadání.

Energy balance in wastewater treatment plants
Novotný, Jan ; Raclavský, Jaroslav (referee) ; Hluštík, Petr (advisor)
This masters thesis is dealing with energetic evaluation of selected municipal WWTP – WWTP Polička. First chapter, introduction explains basic terms and goals of thesis. Second chapter explains energy audit, energy audit process its scope and contents. Third chapter deals with assesing life cycle using LCA (life cycle assesment). Fourth chapter deal with energy consumption at WWTP in Czech Republic as well as in the world. Fifth chapter describes technology of WWTP Polička and its fundamental objects. Sixth chapter is assesment of WWTP Polička from hydraulic point of view and assesment of selected machinery. Further there is summation of capital and operational costs followed by capital investment return.

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.

Chemicals for waste water treatment
Doskočilová, Denisa ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor thesis is to get the reader acquainted first with the history of wastewater treatment in the Czech Republic and also the legislation that relates to waste water treatment. Furthermore, this work will provide an overview of each part of technological wastewater treatment plants and chemicals that can be used in various cases, including their manufacturers and prices.
