Upgrading of wastewater treatment plant by means of MBR technology.
Spratková, Aneta ; Rusník,, Igor (referee) ; Hlavínek, Petr (advisor)
This diploma thesis is focused on the topic of membrane technologies used in wastewater treatment. The research part of the thesis deals with membrane separation of activated sludge, and the focus is on the submerged membrane modules. The thesis contains basic principles of MBR systems, an overview of used membrane modules, modes of operation, advantages and disadvantages of using this process. The practical part of the thesis proposes the intensification of WWTP Perná with using MBR technology. This part includes the technical-economic assessment of the activation WWTP with the third stage of treatment and activation WWTP with MBR.

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.

Recovery of celulose from wastewater
Kobzová, Kamila ; Úterský, Michal (referee) ; Hlavínek, Petr (advisor)
The goal of this bachelor’s thesis is to point to amount of cellulose in water-waste, which manly came from people homes. Other goal is to show possibilities how to obtain this cellulose from sewage in other countries and how to use it afterward. Practical part of this thesis focuses on project which filter cellulose in sewage treatment plant in Brno-Modřice.

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.

Level scraping systems of settlement tanks
Rusník, Tomáš ; Hort, Filip (referee) ; Brandejs, Jan (advisor)
Main topic of this bachelor thesis is analyse of settlement tanks scraping equipements in sewage plants. Settlement tank at the wastewater treatment plant is part of the so-called bio-lines, which is used for the separation of activated sludge from waste water. Activated sludge settles in the settling zone. Part of the sludge flotates to the surface of the tank, usually in the space between the inflow cylinder and overflow edge, respectively. This sludge, biological or chemical origin, may, at the massive occurrence, outflow to the recipient and causes worse quality of the effluent. The sludge is therefore necessary to remove from surface of the settlement tank. Some of the different systems of sludge collection have been developer during last decades. The equipments and their function are descriped in my work.

Energy Optimization of WWTP
Frank, Ivo ; Sousedík, Milan (referee) ; Hlavínek, Petr (advisor)
Objectives of this bachelor thesis are to offer a brief tutorial on how to proceed with the energy audit of the wasterwater treatment plant and offer energy-efficient and economical alternatives to the technologies and equipment currently used for mechanical and biological wastewater treatment processes. Chapter with practical part of the thesis deals with possible applications of retreived knowledge on to operations of WWTP Mikulov in order to optimize its energy efficiency.

IMPACT OF MUNICIPAL POLLUTION ON FISH LIVING IN A SMALL STREAM
HORA, Vojtěch
Main objective of this thesis is evaluation of the impact of extraneous substances that enter Živný stream through the WWTP Prachatice onto the stream's fish population. Brown trout (Salmo trutta m. fario) was selected as a sampling organism. Sampling was conducted in 2012 using an electrical aggregate at three locations. The sample counted a total of 36 fish. Subsequently there was conducted blood sample and tissue analysis using selected biomarkers (vitellogenin and EROD). Furthermore, an analysis of fish tissue and water samples was made to identify presence of selected extraneous substances.Concentration of vitellogenin in blood plasma of male fish in the controled location was zero, in polluted location the average concentration varied between 275 and 573 ng.ml-1. Concentration of vitellogenin in blood plasma of female fish was the lowest at a location directly downstream the WWTP (7 185 823 ng.ml-1). At other locations, the average concentration ranged between 9 250 302 - 11 614 177 ng.ml-1. The activity of liver detoxifying enzymes (EROD) was the highest at polluted locations, between 63,9 - 87,4 pmol.mg-1protein.min-1. In the controled location was the lowest activity EROD (5,4 pmol.mg-1protein.min-1). The result of identification of selected extraneous substances in fish tissues (liver) and in the water is a sum of all detected pharmaceuticals. In fish tissues was the sum of all detected pharmaceuticals in the range from 20,8 to 138,8 ng.g-1, while in water it varied between 0,07 - 3,00 ?g.l-1. The highest values were again measured in polluted areas. The results of the analyses conducted imply, that the present concentrations of extraneous substances in Živný stream downstream from Prachatice have a negative impact onto live organisms.
