Inclusion of the term blue-green infrastructure and a description of the design technical elements used for efficient rainwater management in urban areas. The practical part proposes the solution of the elements of the blue-green infrastructure on Údolní Street in the city of Brno with the requirements of the utility network administrators and the sewer network operator BVK, a.s ..
Study of variants of sewerage in the village Vír
Macík, Ondřej ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
Most of the municipalities in Czech republic have old or even disfunctional sewage systems for built up communal areas. General combined sewage systems built earlier are being today replaced by solutions separating rain waters and sewage waters. Municipality Vír has currently only few sewage branches that consequently flow into Svratka river. Aim of this Diploma Thesis is to propose 3 solutions for sewage produced in communal areas of Vír municipality and its consequent disposal in sewage treatment plant. Each of three solutions feature combined gravity-driven and pressure systems of sewage lines as well as water treatment in proposed MTB as well as household and container WTP. Each of three variant is economically weighed with proposed budget.
Removal of micropollutants from wastewater by adsorbtion.
Trávníček, Jakub ; Macsek, Tomáš (referee) ; Hlavínek, Petr (advisor)
The aim of the thesis is to create a research on the issue of adsorption of micropolutants with a subsequent focus on biochar. The first part therefore deals with the micropolutants themselves, the origin of their formation in wastewater and their negative impact on the health of organisms. It also deals with adsorption technology, discusses its basic knowledge necessary to grasp the topic and describes known adsorbents and their use. It pays special attention to biochar. The second part of the thesis deals with practical filter tests of adsorption abilities of biochar on wastewater from tunnel maintenance and treatment carried out in the laboratory of the AdMaS centre.
Structural and technical condition of the sewer system in the village
Hublová, Nikola ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
The bachelor's thesis is focused on the evaluation of structural and technical condition of the sewer network in a selected municipality. The thesis is divided into two parts. The first part lists the legislation related to the sewer network. Faults occurring on the sewer network are described together with selected factors influencing the condition of the sewer pipe. For fault detection were introduced pipeline monitoring methods with a description of codes intended for the evaluation of qdetected faults in accordance with ČSN EN 13508-2. The second part presents the municipality in which the network passport took place. According to the available documentation, all elements of the sewer network were traced and then geodetically oriented. All shafts were visually inspected and obtained informations were recorded in the register of elements. Selected sections of the pipeline were inspected by a robot with camera and all faults were classified according to the coding system from the standard ČSN EN 13508-2. The overall structural and technical condition of the sewer network was summarized and variants were presented representing the possibilities of how to deal with the information obtained.
Removal of antibiotics from wastewater by advanced oxidation technologies
Macsek, Tomáš ; Rusník,, Igor (referee) ; Bodík,, Igor (referee) ; Hlavínek, Petr (advisor)
Antibiotics are substances that inhibit the growth of microorganisms and are widely used in modern medicine. High consumption of antibiotics correlates with their elevated occurence in sewage systems, from where they are further released into the environment. The threat of their occurrence in the environment is in triggering the formation and spread of antibiotic resistance. This thesis focuses on the removal of selected antibiotics and partly on the antibiotic resistance from wastewater by advanced oxidation processes (AOPs). AOPs are based on the creation of highly reactive hydroxyl radicals, which are able to oxidize even highly persistent substances. The thesis focuses on the purification of effluents from municipal wastewater treatment plants (WWTP), which are identified as the main source of pharmaceutical pollution in the environment, by AOPs mainly based on ozonation. These processes were tested under laboratory conditions on model water as well as under real conditions as the tertiary stage of the treatment at Brno-Modřice WWTP under various operating states. As the results of the performed experiments show, it could be concluded that the studied AOPs are capable of effective degradation of studied antibiotics from the treated medium. Under real conditions, the antibiotics sulfamethoxazole, trimethoprim, azithromycin and clarithromycin were monitored. Output concentrations in each operational state were achieved to be below the limit of detection for all four antibiotics. The application of AOPs based on ozonation as the tertiary step of the treatment also had a positive effect on the reduction of microbial contamination and antibiotic resistance. Within the pilot plant experiments, a reduction of up to 4 orders of magnitude of E.coli, coliform microorganisms and a reduction of their resistant strains in the range of 1.4 - 4.0 logs were observed, compared to the effluent from the WWTP.
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.
Removal of selected pharmaceuticals from the treated wastewater by oxidation processes
Novotný, Hana ; Macsek, Tomáš (referee) ; Hlavínek, Petr (advisor)
The aim of the work is research and summarize the currently available information about micropollutants with a focus on drugs and pesticides. The first part deals with the description, occurrence of micropollutants and their effects on organisms. The second part deals with the possibility of removing selected drugs from wastewater and the application of such methods in practice, and evaluates the effectiveness and economic aspects of O3, O3 + H2O2, O3 + UV and O3 + H2O2 + UV.
Rainwater infiltration
Kračman, Martin ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor´s thesis is to define legislative options of infiltration, retention and drainage of rainwater for household in Czech republic. Thesis describes not only rainwater, but also waste water, the quality and usage of them both. Furthermore, the?amount of usable grey water in household is defined. Then the systems for retention waste water and rainwater are desribed as well as technical principles of their design and purification of rainwater. In the final part od this thesis, the systems for usage of?rainwater and grey water are designed. Finally, the designed systems are evaluated and their feasibility is assessed.
Sewer mining
Šebek, Josef ; Macsek, Tomáš (referee) ; Hlavínek, Petr (advisor)
This bachelor thesis presents the topic of waste water reuse straight from the sewer system (sewer mining). It contains energy recovery (heat recovery in particular) from sewer system as well as wastewater treatment and reuse in demanded locations, in compliance with the policies of circular economy. The first part contains research of wastewater topic. Individual components of municipal wastewater, treatment and reuse options are characterized in this part of thesis followed by more detailed description of methods and technologies for heat recuperation from wastewater; and available technologies for sewer mining options at the end of the first part. The second part contains a technical study about wastewater heat recovery on a specific location.
