Mechanical cleaner-machine
Čejda, Robert ; Malach, František (referee) ; Malášek, Jiří (advisor)
The aim of my diploma thesis is to design a construction of a mechanical fine rack cleaner machine including an appropriate design of gear mechanism and its attachment to the frame. The cleaner machine is located in the inflow system of a turbine in front of the object of small hydro power station. The design of the construction of the cleaner machine will be based on a drawing documentation and a report with needed analytic and FEM calculations.

Hydraulic cleaner-machine
Homoláč, Zdeněk ; Malach, František (referee) ; Malášek, Jiří (advisor)
The diploma thesis deals with construction design mechanically rake screens with hydraulic drive. The diploma thesis is composet of several parts, in a first past is an overwiew of mechanical method of cleaning screams. The second part deals of diploma thesis deals with product design rakes raking mechanism. The third part is an analysis of machine parts and describe their functions. It is then carried out stress analysis using fine element methods (FEM) in the program I-deas.

Wastewater pretreatment at sewerage network
Doskočilová, Denisa ; Sousedík, Milan (referee) ; Hlavínek, Petr (advisor)
ABSTARCT The aim of this thesis is to treat the problem of wastewater pretreatment on the sewer network with a focus on storm water overflow and their impact on waterways with regard to The Methodological Manual for Assessment of storm water overflow within uniform sewerage systems in urban areas. This work describes the legislation relating to storm water overflow and includes comparison with other countries. Furthermore, there is processed the outline of objects and equipment which can be used for wastewater pre-treatment in the sewer network. In the practical part of the thesis there is designed a new solution for the mobile spillway edge of the storm water overflow OK2A, which is located within the sewer network in Brno. In the practical part of the paper there is depicted the project documentation of newly designed equipment and objects. Water management companies, design offices, students and the general public can use this thesis as an inspiration.

The amount of waste from wastewater treatment process
Žíla, Radim ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
This Bachelor's Thesis is focused on the amount of waste produced by the sewage treatment plants for the amount up to 2.000 equivalent inhabitants with the gravitational inflow. There are all the types of individual sewage treatment plants of the size up to 2.000 equivalent inhabitants listed in the first section of the theoretical part and the second section of the theoretical part deals with the thorough analysis of all the objects within the sewage treatment plant, their draft specifications and the description of the waste handeling. The practical part of this Bachelor's Thesis deals with the evaluation of the production of waste for the amount up to 2.000 equivalent inhabitants in individual municipalities within the South Moravian region. More specifically it describes the waste of screenings, sand, insoluble substances and sludge on one equivalent inhabitant and its subsequent comparison with the regulation according to ČSN. The evaluation compares all the municipalities among each other and their production of waste is also compared to ČSN.

Adaptation of the Watermill
Pavlík, Jan ; Hudec, Martin (referee) ; Klas, Roman (advisor)
The bachelor´s thesis is composed of two parts. In the first part, there is a generally discourse about small water power plants, their structural design, mechanical equipment and economical efficiency and its function is to create the basic conception of the waterwork. The second one deals concretely with the small water power plant in Crhov, that was rebuilt from the original mill by Mr. Petr König in 1990s.

Hydraulic rake screen
Růčka, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
This thesis deals with the structural design of hydraulic raking screens placed before a sewage treatment plant. The first part describes various possibilities of water treatment from individual particles. The second part deals with basic parameters of screens and calculations of propelling power for previously chosen structure. Furthermore, a strength check of structure under the most unfavourable load is performed. Drawings of the whole assembly of hydraulic raking screens, plus a few selected components are attached to the thesis.

Hydraulically driven screens
Forman, Ladislav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main objective of this work is the calculation of selected parts of hydraulically driven screens such as cleaning equipment before entering the small hydro power plants. The thesis is divided into two parts. The first part focuses mainly on the calculation of hydraulic mechanism for cleaning screens. The second part contains a drawing of the general assembly hydraulically driven screens and sub-assemblies.

Flow structure in shaft spillway area of of Labská dam
Šváb, Jiří ; Pařílková, Jana (referee) ; Zachoval, Zbyněk (advisor)
The bachelor thesis is divided into literary research and practical part (own measurement). The content of the literary research is a description of the shaft spillway, the Labská dam and the measuring equipment. The practical part is focused on measurement of the horizontal velocity, flow distribution and water surface elevation on the shaft spillway physical model. The results are horizontal velocity for two levels, water surface elevation and flow distribution.
