Hoferková, Lenka ; Hlavínek, Petr (referee) ; Hluštík, Petr (advisor)
Energy management is topical issue and we have to solve this global problem. There is also an option to exploit the renewable energy. The source might be biogas produced during anaerobic sludge stabilization. This bachelor thesis deals with using biogas in cogeneration units at sewage water plant. First section covers the main Czech and EU legislation and regulations in the field of water treatment, sewage sludge treatment and cogeneration. The next section is devoted to production of biogas and possibility of utilization in cogeneration. The thesis divides cogeneration systems and mentions the main parameters such as energy efficient and wattage. Local and European companies are chosen from the fields of manufacturer. The practical part deals with designing of cogeneration unit at sewage water plant Zdar nad Sazavou. According to calculated and measured parameter adequate unit from local manufacturer Tedom is chosen. Moreover, there are other solutions for replacing the engine in the current unit (by Tedom) or general repair (by Motorgas). All options are evaluated from the view of profitable investment. The conclusion is that It would be preferable to replace the engine.

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.
