Technologies of reuse of wastewater in place of need
Podhrázský, Martin ; Ševčík, Jan (referee) ; Hlavínek, Petr (advisor)
Final thesis is focusing on possibilities hidden in the potential of wastewaters in sewers. The goal of this thesis is to present technologies and experiences with water reclamation and with heat recovery systems using wastewaters as a source of heat energy. The theoretical part is divided in two main topics. The first topic is focused on bringing important knowledge and experiences with designing and operating decentralized sewer mining systems, which are, due to less favourable environmental conditions, largely applicated and developed in countries such as Australia, California, etc. The second topic is focusing on heat recovery from sewage water and possibilities of heating and cooling buildings. A possibility of using heat energy from sewage for heating and cooling a swimming pool building located in Brno, Czech Republic was assessed in the last part of this thesis. As a source of wastewater was considered a sewer main located near the pool building. Payback periods and economical effectivity of investing into wastewater heat recovery system was compared with centralized heat supply system, which is a very common source of heat energy in Czech Republic.

Removal of selected medicines from waste water by oxidation processes
Úterský, Michal ; Rusník,, Igor (referee) ; Kučerík,, Jiří (referee) ; Hlavínek, Petr (advisor)
A concept of removing of pharmaceuticals from a wastewater is become more important topic. Currently we can see the increasing consumption of pharmaceuticals worldwide and an increasing effective doses of pharmaceuticals due to the resistance of microorganisms. Generally, a medicine means an active substance or their mixtures. The medicine is used for positive influencing of human’s and animal’s health. Nevertheless, a long term presence of pharmaceuticals in the environment leads to chronic toxic aquatic organisms, possibilities of multiplication of multi-resistant pathogenic bacterial strains, deterioration of reproduction of animals and their endocrine system. My dissertation is focused on a removing of pharmaceuticals from the wastewater via advanced oxidation processes. Results of research showed that the advanced oxidation processes are able to reduce concentration of pharmaceuticals. Mainly priority of this problem is other cleaning level of the wastewater which flows away from urban WWTP to river. Wastewaters consist of large volume of pharmaceuticals due to excrements, urination and flushing of outdated pharmaceuticals. An efficiency of advanced oxidation processes on the removal selected types of pharmaceuticals is a part of practical selection of the dissertation.

Assessment of hydraulic reliability of drainage system in urban area and solution of extra-urban storm water.
Šebek, Josef ; Macsek, Tomáš (referee) ; Hlavínek, Petr (advisor)
This diploma thesis presents the topic of urban drainage systems. The first theoretical part contains methods and options for urban drainage systems, stormwater management, blue-green infrastructure (BGI) in urban areas and introduction of numerical modelling of sewerage systems. The application of modelling platforms is further described in the feasibility study in the practical part of this thesis. By using the simulation model, the study assesses the hydraulic reliability of the drainage system in the city of Jedovnice in the Czech Republic, identifies hydraulic issues and their causes on the urban drainage system. The second part of the study assesses extra-urban stormwater inflow from fields around the city caused by heavy rainfalls, which causes local flooding in the urban area. The identification as well as proposed solutions and capital expenditures, their comparison and recommendation of the optimal solution are included in the study.

Storm water management in urban areas.
Vaculík, Tomáš ; Tauš,, Miroslav (referee) ; Hlavínek, Petr (advisor)
The diploma thesis is focused on Storm water management in urban areas. The first task for processing thesis was to arrange meeting with MČ Brno - Bohunice Ing. Antonín Crha, who has provided necessary information about the targeted location the and the reservoir for accumulation of rainwater collected. The practical part of the thesis is to capture the rainwater drainage in the existing rainwater sewerage system using the newly built pumping station and then pumping into the existing, unused reservoir. Accumulated water in the reservoir is planned to be used for the needs of the city, gardeners and other customers. The first part of the diploma thesis describes the management of refined water in the Czech Republic, Denmark and Germany. The first part also provides description of measures and technologies for the management of rainwater. Finally, there is description of the pumping station and borehole objects and the program for calculating the rainfall from the urbanized area. In the practical part of the diploma thesis the selected variants are described, rewarded and evaluated. The diploma thesis deals with two variants, that are guided along the same route, with the difference of the construction of the drilled well in the second variant. Both variants are handled by pumping. The option of the gravity inflow was rejected because of the large countersink of rainwater sewerage.
