Options eliminate odors in sewer network
Žíla, Radim ; Malaník,, Stanislav (referee) ; Hluštík, Petr (advisor)
The diploma thesis focuses on the possibility of removing odor on the sewer network. The first part of the research describes how the odor is generally perceived and what legislation regulates its quantity in the air. The second part of the research focuses on problems of formation of smelting sulfate on the sewer network. This section describes the formation of sulfane as a major component of odor. Further disclosed are methods for its removal, and the ways in which the odor is measured. The practical part deals with laboratory testing of pre-selected fillings in order to determine their ability to remove odorous sulfane. In the second part, on-line measurements are made to determine the causes of sulphan formation in a given location.

Study of sewer network of selected municipality
Remešová, Terezie ; Lžičař, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The main goal of this diploma thesis is the proposal of sewerage variants of local parts of village Pačlavice, which are villages Pornice and Lhota. For individual municipalities are proposed three partially different variants, which vary mainly in the way of wastewater draining and wastewater treatment. All three variants are evaluate from an economic and technical point of view and on the basis of evaluation is propose a variant, which is in my opinion, the most suitable for these municipalities. In the villages Pornice, Lhota and Pačlavice are proposed new delivery and gravity sections, associated objects of overflow chambers with pumping stations, independent overflow chambers or separate pumping stations that complement the existing combined sewer system to ensure the drainage of wastewater to wastewater treatment plant and following treatment of this water.

Eliminating odors in the sewer network
Novotný, Jiří ; Malaník,, Stanislav (referee) ; Hluštík, Petr (advisor)
The diploma thesis focusses on the elimination of odor in the sewer system. Firstly, the paper contains the research in problematics of the origin, control and risks of the hydrogen sulfide for humans as well as for the sewer system. Secondly, the paper describes methods for hydrogen sulfide removal from water, air and in addition to that the selected sorbents are described in detail. Practical part deals with sorbent testing for hydrogen sulfide removal in laboratory environment. The practical part also follows up the odor in the particular area through sorption on sewer filters. From the measured data and from the results of the laboratory analyzes the consequences of the odor are evaluated and recommendations for the operator are presented.

Assessment of sewerage systems of urban catchments
Velikovská, Kristýna ; Raček, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The bachelor thesis prepares new and present knowledge of assessment of sewerage systems of urban catchments. Theoretical part of the thesis describes classical and contemporary integrated concept of draining waste water from urban catchments. In pursuance of contemporary integrated concept, there is a list of methods, which is used for monitoring conditions of sewer system, making a simulative modeling and solving of elementar tasks in water management. Practical part of the thesis uses gained knowledge to assess sewerage systems of Kladeruby nad Oslavou village. The bachelor thesis is written with respect to valid legislation.

Sink disposers and theirs importance in biological degradable waste removal.
Amemori, Anna ; Benešová, Libuše (advisor) ; Doležalová, Markéta (referee)
Some 30 - 50 % of municipal solid waste (MSW) is biodegradable waste. Most of this waste is sent to landfills or incinerated and is not recovered. According to Waste Management Plan of Czech Republic based on the Landfill Directive of EU, Czech Republic should to reduce weight of biodegradable waste sent to lanndfills to 75 % in 2010 and 35 % in 2020 compared with the amount that had been landfilled in 1995. In rural areas biodegradable waste is fed to animals or treated by home composting. However in urban areas the collection of separated biowaste is problem for a long time. Food waste disposers (FWDs) presents interesting alternative for the biowaste disposal. They enable the separation of food waste at source by shreding it in a kitchen sink. FWDs utilize existing infrastructure of sewer system to transport shreded wastes to wastewater treatment plants (WWTP). Wastes can be disposed in WWTPs by anaerobic digestion - the best method for disposal of food waste of animal origin. This work concentrates on literature research of studies about feasibility of FWD as a instrument for biodegradable waste removal and compares arguments for and against using of FWDs in households. Majority of studies shows no complications in sewer system and on WWTP after instalation of FWDs. Energetic and hydraulic consumption...

Hydraulic calculation of sewage system in Lipůvka
Balas, Jan ; Raček, Jakub (referee) ; Hluštík, Petr (advisor)
Diploma thesis is focused on hydraulic assessment of Lipůvka´s sewer system, done by dynamic rainfall-runoff simulation model. Because of this fact, chapter about mathematical models is included. Commonly used programs to this actions are listed as well. Next part of the thesis describes monitoring campaign, which was done in Lipůvka and results are used to calibrate the simulation model. Hydraulic assessment of sewer system by this calibrated model was done.

Mathematical models of retention object of urban drainage
Pavlík, Ondřej ; Stanko,, Ing Štefan (referee) ; Pollert,, Jaroslav (referee) ; Prax, Petr (advisor)
This work deals with the use of 3D mathematical models of fluid in water management practice. Using 3D mathematical model was assessed retention tank Jeneweinova, which is situated on a sewer network of the city of Brno and is an important object of urban drainage. Retention basin designed to keep overflow from CSO chambers to Svratka and Svitavský náhon during storm events. Retention tank Jeneweinova is suitable for the assessment, because tank was designed bassed the Master Plan drainage of Brno using 1D mathematical model. Another factor was the physical model, which was build in LVV Vin FAST BUT. And finally, near the retention tank will be installed measurement on the sewerage network, which will be able to verify the results whitch has been predicted in this work. Mathematical model of retention tanks Jeneweinova was build in software FLOW-3D. FLOW-3D is a general purpose CFD (Computational Fluid Dynamics) software for flow of fluid in steady and unsteady mode and uses computational techniques to solve the equations of motion of fluids. This software is mainly used for the calculation of hydraulic fluids, gas flow and heat transfer simulations. Results from 3D mathematical model has been compared with the values in the physical and 1D mathematical model.

Renovation of sewer network with CIPP methods
Holeš, Petr ; Helcelet, Marek (referee) ; Raclavský, Jaroslav (advisor)
Diploma thesis makes a summary of today’s state of CIPP methods designed for sewer relining. Thesis presents classification of CIPP methods between other NO-DIG technologies. Then CIPP methods are divided into groups according to the material used for the liner, applied resin, installation method and curing method. Designing of the CIPP liner used for sewer renovation is also part of this diploma thesis. The result of the theoretical part of this work is a table, which states suitability of particular methods for use in a sewer of specific technical properties. Practical part of bachelor’s thesis is dealing with the analysis of defects of an existing sewer in the city Přerov. Analysis was done due to the camera examination provided by the company Wombat s.r.o. Later the table developed in theoretical part was applied, and then the suitability of use of all parameters of CIPP liners was commented. At the end the plan of works is designed, with the plan for pumping of water included.
