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“.

Removal of selected xenobiotics at municipal WWTP´s
Žižlavská, Adéla ; Rusník,, Igor (referee) ; Bodík,, Igor (referee) ; Hlavínek, Petr (advisor)
The development of the chemical and pharmaceutical industry and the massive use of synthetic substances in various industries has become indispensable for our society. Unfortunately, this progress has brought a whole new kind of pollution. It is a group of substances which imagine for living organisms’ greater risk than 'normal' organic pollution. Because they have extraneous origin compared with naturally occurring compounds, they are called "Xenobiotics." It is a group comprising a large number of different substances, with dissimilar physical, chemical and biological properties such as pharmaceuticals, pesticides, detergents, paints, varnishes, plastic packaging, food additives, cosmetic products, drugs, and many others. Although these substances began to enter the water cycle as early as 30 years of the 20th century, their concentration often moves to the limit of the detection limit, so their presence in the water began to be examined in more detail in the 1980s, following the development of analytical technologies chemical composition of water. The main danger of these substances is that doesn’t primarily effect on water quality, but directly affect on the organisms by confusing of the endocrine system or by directly damaging RNA or DNA, causing mutagenic changes, cancer-causing proliferation, birth defects, metabolic disorders, gender changes, the degeneration of reproductive capacity of entire populations or the disappearance of self-preservation instinct. The source of xenobiotics in the water cycle is predominantly wastewater, which generated through the wastewater treatment, which not designed to eliminate this type of pollution. he dissertation thesis deals with the issue of xenobiotics in wastewater and is divided into the theoretical and experimental part. The theoretical part summarizes the xenobiotics current state of knowledge in wastewater from their history, origin, classification, possibilities of elimination to impacts on the environ

Energetic utilisation of sewage sludge
Tlašek, Miroslav ; Stříteský, Luboš (referee) ; Hlavínek, Petr (advisor)
Diploma thesis deals with issues related to final treatment sludge. Sewage sludge is an inevitable product of wastewater treatment. Also, most of them concentrated pollution. Most of pollution are concentrated in to them. And because it contains a large percentage of combustibles. Before thermal utilization, it is necessary to appropriately adjust the sludge. Thermal sludge utilization offers the most effective method of energy recovery. It is an energy conversion in the sludge, to heat and electricity. In the vast majority, if not the co-firing, it is necessary to modify the sludge and so it is dried. This is the optimal use of modern technology. There are several variations possible use. Unfortunately it is not in general able to propose the most appropriate technology or methodology, how to make best use of sewage sludge. Specific assignment usually have their own characteristics. In my work I will therefore first try to outline possible technology and in the second part to suggest sludge terminal for WWTP Hodonín.

Problems of disposal with rainwater from a communication
Oprchalová, Marie ; Pollert,, Jaroslav (referee) ; Palčík,, Jiří (referee) ; Hlavínek, Petr (advisor)
Transportation has unfavorably influence on a quality of enviroment. Increase of traffic leads to construction of new motorways and to intensify the traffic on current comunications. A consequence is more polluted hard surfaces, when surface-wash contaminate soil, surface water and underground water. Devices for treating contamined water, such as oil-separators, are very actual in these days. The subject of this thesis was to test the possibilities of increasing effectiveness of mechanical separator for light liquids by installing various types of constructions. Target was to determine effectiveness of this conventional technology, which is energetically and technically simple and find out applicability for first step cleaning and further usage.
