Energy balance of urban wastewater treatment plants
Čížová, Barbora ; Bartoník, Adam (referee) ; Hluštík, Petr (advisor)
The research part of the diploma thesis is focused on an issue of energy consumption in sludge treatment at wastewater treatment plants divided by the number of population equivalent. The aim of the practical part is to set indicators and propose evaluative criteria concerning energy performance of urban wastewater treatment plants. The verification of proposed criteria and energetic analysis result from data of the wastewater treatment plant in Novy Jicin.

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.

Energy meter with PLC communication
Szalbot, Michal ; Mlýnek, Petr (referee) ; Koutný, Martin (advisor)
Our thesis is about development of equipment, which combine two technology. First technology is wattmeter which is used to energy measurement and second is Power line communication. Wattmeter needs two variables for measurement, voltage and current. Voltage measurement is less difficult than measurement of current. Voltage can be reduce and measured by A/D converter. Current has to be transform to voltage and than can be measured same way. To do that we use current transformer. Than we design program for the microcontroller, involvement and PCB. Wattmeter is connect to PLC modem which has been chosen. Fusing this two technology we create wattmeter network. Next step was program which is used to network control and data collecting. This data are used to create charts in web application.

Energy performance of wastewater treatment plants
Čížová, Barbora ; Bogáňová, Ida (referee) ; Hluštík, Petr (advisor)
The retrieval part of the bachelorś thesis deals with legislation concerning energy audit and energy audit processing at wastewater treatment plants. Further work is aimed at assessing the energy performance, energy optimization and operation of energy self-sufficiency wastewater treatment plants. The practical part is focused on the comparison of the specific energy consumption for wastewater treatment in Koprivnice. The aim is to assess the energy performance of the selected indicators. This is an assessment of the m3 of waste water, kg BOD5 removed and the number of population equivalent.

Economic return earth-sheltered houses and their influence on environment
Spoustová, Michaela ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The subject of this work is comparing economic return and influence on environment by earth-sheltered house and classic house. Attention will be concentrated on construction process these houses from the beginning to approval of construction, the advantages and disadvantages resulting from the construction, which will be compared with neighboring states, especially with Germany and Austria. The work first briefly describes earth-sheltered houses, their history and use renewable energy sources, then focuses on comparing the two types of houses. The main objective of this work is to confirm the hypothesis about the benefits of building earth-sheltered houses, despite high initial costs and increased interest in population of these houses in recent years. To calculate the repayment time will be apply cost -- benefit analysis and questionnaire survey. At the conclusion work summarizes the results obtained and confirm of reject the hypothesis examined.
