Use of heat from wastewater
Tlašek, Miroslav ; Vachovec, Roman (referee) ; Hlavínek, Petr (advisor)
The bachelor thesis deals with the problems associated with heat recovery from waste water and energy intensity of wastewater treatment plants. Current technologies allow you to recover heat that was inserted into the hot water. These technologies can be used for small performances in houses and for large building amenities too. It has been shown that by using a heat pump, low-potential heat waste water can be converted into useful heat for heating and hot water. Not only these heat pumps are environmentally friendly environments, but they can also compete with traditional sources of heat. The aim of the study was to describe these technologies and to minimize the energy that is wasted us „will drain into the canal“.
Chemicals for waste water treatment
Doskočilová, Denisa ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor thesis is to get the reader acquainted first with the history of wastewater treatment in the Czech Republic and also the legislation that relates to waste water treatment. Furthermore, this work will provide an overview of each part of technological wastewater treatment plants and chemicals that can be used in various cases, including their manufacturers and prices. In the practical part there will be conducted a calculation of the amount of coagulant including its annual costs for WWTP Čebín. This material may be an inspiration for either design offices or water managing companies and also the general public.
Use of EIS method for determination of sedimentation in stady liquid
Hradilová, Iva ; Vachovec, Roman (referee) ; Špano, Miroslav (advisor)
Determination of interface between sediment and liquid belongs to common tasks in various fields of industry like sewage and/or water treatment. The aim of presented work is verification of suitability of electrical impedance spectrometry (EIS) method for determination of interface between soil and water. The suitability was verified on three samples of soil. The first one was a sand while other two were loam of different grain sizes. Introduction of both the EIS method and Z-meter III instrument used for measurements is presented in this work too. Within conclusions the suitability of the method and provability in determination of water-soil interface are discussed.
