The use of the reactor with sludge cloud and external biomass separator for methane production from the substrate for Biogast Plant
 ŽIVNÝ, Jakub
The aim of the study was to compere the reactor with sludge cloud and external separator biomass in different modes. This typ of reactor is principally used in wastewater treatment and in this work was designed for production of biogas from biosmass, commonly used in agricultural biogas plants. The reactor assembly was prepared in the laboratory of the available glass flasks, connected by rubber tubing and mixing pump. The entire device was immersed in a water bath heated thermostat. For the purpose of this work was used samples from biogas Týnec near Dobrovice at Mladoboleslavko. The reaktor was injectable liquid portion, formed after adjusment method IFBB (Integrated Generation of Solid Fuel and Biogas from Biomass). The principle of this method consists in separating the liquid and solid components of biomass. Operation of the reactor was carried out in three stirring models: without stirring, medium stirring, intensive stirring. Further, the operation was compared at 40°C and 53 °C in a mode without stirring. This monitoring is carried abut for five hours. The specimens was taken every hour and after drying to COD (determine chemical oxygen demand), which expresses the degree of degradation of organic matter. The results show that the laboratory devie model stirring does not show. However, the temperature change from 40°C to 53°C showed an increased degradation of organic matter.

The design of the production of biogas from fresh grass.
 ŽIVNÝ, Jakub
Work is concered with the biogas production from the fresh grass mass, which come up when the grass is being cut on regular basis in the parks and side parts of communities and cities. There is a detailed description of the biogas production defined in the beginning of the Theses in the literature overview. Next, we define the material properties suitable for the biogas production, concerning on the grass mass. In practice, there is a prototype example showing how the biogas station could manipulate the fresh grass mess in real, linked to the harvest line.
