Optimization of Energy Flow During WWTP Operation - Smart Area Net
Pěcha, Jiří ; Máša, Vítězslav (referee) ; Braciník,, Peter (referee) ; Mastný, Petr (advisor)
The dissertation work deals with the issue of water treatment and possibilities of energy savings during the operation of sewage treatment plants. The aim of the work is to find the potential of alternative energy use, economical consumption, improvement of the facility system management and quality improvement of the wastewater treatment process. In the first part of the work, operating processes, energy flows and energy savings are discussed. To analyze the problematics, larger sewage treatment plants were chosen. Thanks to their size, it was easier to find critical points and test the usage of renewable sources in operation. After the energy audit, the individual processes were assessed and real operation pitfalls were determined. Further steps led to focusing on smaller facilities up to 2 000 PE. This step was carried out with the intention of preparing these plants for the planned legislative change and helping to create or modernize more energy-efficient solutions. Thanks to the establishment of consortium of Brno University of Technology, the Department of Electric Power Engineering and a company dealing with water treatment and automation control, a solution was created that modernize the electrical, automation and water treatment part of the plant operation. This innovative application was installed in the sewage treatment plant, where the issues were debugged, control algorithms were tested and the entire operation was launched in automatic mode. At the end of the wastewater treatment plant modernization, PV panels were installed on the roof, thus partially suppling the object with renewable energy.

The use of greywater and rainwater for public facilities
Korytář, Ivo ; Raček, Jakub (referee) ; Raclavský, Jaroslav (advisor)
This paper analyzes the usage of grey and rain water in civic amenities. Its main goal is to assess the advantages and disadvantages of the grey and rain water and to dissect the problematic of rain water quality. In order to reach its goal, the current paper will analyze the already applied system of using grey water, specifically in the case of MOSAIC HOUSE in Prague, which was the first in the Czech Republic and second in the world to use grey water for heat purposes. In conclusion, this Bachelor’s paper presents one object of civic amenities, specifically the guesthouse U Cerneho psa in Cesky Krumlov, with the proposal of grey water purifier by ASIO s.r.o. and grey water seepage object from the same company together with a projected balance sheet.

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.

Removal of selected organic pollutants from water using advanced oxidation processes
Dalajková, Nikola ; Vávrová, Milada (referee) ; Repková, Martina (advisor)
The aim of this diploma thesis is the determination of selected organic pollutants with a focus on artificial sweeteners in waste water from wastewater treatment plant (WWTP) Modřice and the subsequent degradation of the thus obtained concentrations in model water using advanced oxidation processes (AOP). Two sweeteners were determined, namely sucralose and saccharin found in waste water. Synthetic sweeteners are not sufficiently cleaned in the WWTP and penetrate the environment. Effective processes for removing organic substances, including alternative sweeteners, are AOP processes. These processes are based on reactions of highly reactive hydroxyl radical (OH·), which is produced by many chemical reactions. Generally, they use ozone (O3) and hydrogen peroxide (H2O2). On sampling, wastewater samples were treated with Solid Phase Extraction (SPE) and then evaluated by HPLC/MS (High Performance Liquid Chromatography). In observing the degradation of selected sweeteners, three AOP methods were used: O3/UV, H2O2/UV and O3/H2O2. For each of these methods, the efficiency of degradation of sucralose and saccharin was investigated. From the evaluated data it was found that the most efficient AOP process for removing artificial sweeteners from water is the O3/H2O2 method.

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.

Energy Performance of sewerage networks
Žďára, Jan ; Hluštík, Petr (referee) ; Raclavský, Jaroslav (advisor)
First section of this master thesis is background research of energy demand of sewer systems. Intrudoctory chapter explains basic concepts. Second chapter is dealing with Czech and European legislation concerning energy consumption of water service. Third chapter describes energy demand of sewer systems. In this chapter there are described conventional gravity, vakuum and pressure sewer systems and components with major power consumption. Fourth chapter describes actual state of energy demand of WWTP and possible ways of improving power consumption of WWTP. Second section is a review of energy consumtion of vacuum systems of five different municipalities including one WWTP. Measured and evaluated outputs were used to create energy audit methodology for sewer systems.

GDPR in non-profit organization
Vařechová, Alice ; Ruda, Tomáš (advisor) ; Sýkorová, Barbora (referee)
Title: GDPR in non-profit organization Objectives: The theoretical part summarizes the laws, regulations and regulations in the field of GDPR. The practical part focuses on the specific area of sport and the GDPR solution in ČUS and ČOV organizations. The main objective of the work is to evaluate the GDPR procedures and recommendations for the non-profit organizations made by CUS and ČOV organization, their comparison and recommendations for improvement of the final document related to regulation of GDPR in general in Czech sport area. Methods: The work includes analysis, evaluation, comparison and adequate proposals together with recommendations for improvement. Relevant data are obtained from available documents and on the basis of semi-structured interviews with selected representatives and members of ČUS, ČOV and specialized companies processing GDPRs in these organizations. Results: In order to examine the available documents on GDPR in sport, it was found that the Česká unie sportu is the most active in this topic and tries to publish all documents on the website. The aim of this work was to create a handbook that could be helpful in capturing and processing GDPR in smaller sports non-profit organizations that are not under the directions of a larger roof organization. Keywords: GDPR, ČUS,...
