Diverzita makrozoobentosu v Evropsky významné lokalitě výskytu raka kamenáče (Austropotamobius torrentium)
The "Zákolanský potok" takes part in European nature program Special Area of Conservation because of the presence of stone crayfish (Austropotamobius torentium), which is listed as threatened species. The area around brook is intensively agriculturally cultivated. Water from wastewater treatments plants is drained to the local brooks. The aim of the work was to describe diversity of macrozoobenthos on the brook called "Zákolanský potok". Further aim was to evaluate the ecological condition of the watercourse using biotic indexes. The samples of macrobenthos were taken from three profiles in five sampling periods. Profile 1 was control, profile 2 was under the wastewater treatments plants and the third profile was placed down the stream. Diversity, biomass, saprobic index, BMWP, and ASTP scores were evaluated for the community of macrozoobenthos. The saprobic index was evaluated to the beta-mezosaprobity value (2.0-2.4) in the first profile, the saprobic index on the second profile showed a relatively wide range from worse oligosaprobity to worse beta-mesosaprobity (1.2-2.4). On the third profile, the saprobic index ranged from better beta-mesosaprobity to better alpha-mesosaprobity (1.6-2.6). The BMWP and ASPT scores in all profiles refer to medium to low quality aquatic environments. The diversity of the community gained the best values on the 3rd profile, here was found with one more taxon than on the 1st profile. With increasing organic load, diversity decreased on the 2nd profile, although a more sensitive species was found here.

The practical part also includes a design of the excursion to the seweage treatment in Benesov. The aim of the thesis is to work on the issue of water purification, which could serve teachers as a guide to the teaching of pupils, they are able to answer the questions...
Optimizing the operation of wastewater treatment plants
Singrová, Veronika ; Bábíček, Richard (referee) ; Hluštík, Petr (advisor)
The aim of this diploma thesis is to evaluate two selected wastewater treatment plants and to propose appropriate measures related to optimization of operation. Wastewater treatment plants are from the Jihomoravský and Zlínský regions and both come under the category 2 001 - 10 000 equivalent inhabitants. In the diploma thesis there is an assessment of construction objects, machinery, cleaning efficiency and energy performance of both WWTPs. The calculations are based on the real measured values for the last three years and on the basic parameters of individual objects and equipment. The present state of the two wastewater treatment plants is summarized and optimization proposals are sorted by importance.

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.

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.
