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.

Alternative solution and strength check of mechanical screens
Sommer, Matěj ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis deals with a new design of bar screens. The goal was to come up with an alternative design to already existing device by INKOS a. s. In the first part, there is a summary of various machines working in similiar conditions. The insights gained by this research influenced the design of the new device. It utilizes well proven solutions from previous projects, but some of these were reworked and a few new functions were added. Second part of the thesis describes the analytical solutions, which were used to determine the forces in the assembly during the operation of the device. Based on the results of these calculations, a strength analysis of important components was performed using the finite element method. The result of this thesis is the design and optimization of new bar screens, including engineering drawings and tools for its further development.

Sewage sludge treatment
Adamus, Petr ; Havlásek, Martin (referee) ; Zejda, Vojtěch (advisor)
The first part of bachelor’s thesis deals with waste water treatment up to the phase, when the sewage sludge is created. Then follows the summary of available sludge treatment and disposal methods and their description. Next part is about legislative overview and a summary of the limits imposed on waste water treatment plants. In the last part, the bachelor thesis deals with description of sludge properties and their measurement methods. The practical part contains measurement and calculation of sewage sludge properties, exactly calculation of dry matter by determination of dry residue and determination of loss on ignition in sludge.

Sludge Pumping on WWTP
Fadrný, Tomáš ; Medek, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
This diploma thesis deals with the best solution design for a sludge fitting, especially focusing on the right choice of pumps for the waste water treatment plant in Prostějov. The pumps were selected for a circulation pipeline, which heats up the sludge. Several measurements were carried out in order to determine the statistical evaluation of the properties of the pumped medium. The figures gained were used to calculate pressure losses.The diploma thesis is divided into two parts. The first part provides a theoretical analysis of the problem and the second part presents the results and subsequently the reasoning for the new selection of pumps in order to change the WWTP technology from the mesophilic to the thermophilic sludge digestion. The test records describing the testing of the individual samples of the pumped sludge are attached.

Design of the concrete sewage plant
Štramberský, Martin ; Strnad,, Jiří (referee) ; Zich, Miloš (advisor)
The subject of my bachelor's thesis is a static design of a sewage plant reservoir, dimensioning and examination of the construction part for Capacity Limit State and Applicability Limit State. Design documentation is included in the project. The aim of this thesis was to design the reservoir in such a way that there would be no cracks in the concrete. The calculations were carried out in accordance with Eurocode 2.

The partial model of sewage treatment plant
Novák, Petr ; Ptáček, Michal (referee) ; Radil, Lukáš (advisor)
The thesis deals with wastewater treatment plants (WWTPs). For the energetic self-sufficiency of the WWTP, it is necessary to study the operational background, equipment and their possible operational prediction for energy distribution over time and adaptation to any renewable energy (RES). It is also possible to optimize the operation to maximize the equalization of the input power. We're talking about small WWTPs up to 500 EP. Large purification blocks are also an option. The student will evaluate the current state of knowledge and try to design and possibly implement the financial savings of the given concept.

Harvesting and reuse of cellulose from wastewater
Kobzová, Kamila ; Úterský, Michal (referee) ; Hlavínek, Petr (advisor)
The goal of this diploma thesis is to highlight the properties of cellulose fibers obtained from waste water and the importance of recycling of raw materials. The main objective is then to further explore the possibilities of using cellulose fibers as a valuable product on the market. The practical part of the thesis is focused on specific research of cellulose properties and design of equipment for sewage treatment plant according to its size.
