Alternative solution and strength check of mechanical screens
Sommer, Matěj ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis deals with a new design of bar screens. The goal was to come up with an alternative design to already existing device by INKOS a. s. In the first part, there is a summary of various machines working in similiar conditions. The insights gained by this research influenced the design of the new device. It utilizes well proven solutions from previous projects, but some of these were reworked and a few new functions were added. Second part of the thesis describes the analytical solutions, which were used to determine the forces in the assembly during the operation of the device. Based on the results of these calculations, a strength analysis of important components was performed using the finite element method. The result of this thesis is the design and optimization of new bar screens, including engineering drawings and tools for its further development.

Development of local roads in Přibyslavice
Dušek, Martin ; Halodová, Klára (referee) ; Všetečka, Martin (advisor)
The aim of the diploma thesis is to help the town of Přibyslavice with the development of local communications. This includes project work based on the current needs of the town and related consultations with local representatives and building authority. First, a passportization of local communications was drawn and subsequently, widening of the communication network by three new roads was suggested. This will enable creation of new building plots. New sewage and rainwater drainage, together with water conduit, were designed. Emphasis was put on avoiding interference with plots not owned by the town, on comfortable access to currently used plots, safe connection to the existing regional road no. III/3798, and sufficient radius for passage of firefighters and a garbage truck.

The possibilities to combine biogas production and biowaste hydrothermal carbonization
Usťak, Sergej ; Honzík, Roman ; Muňoz, jakub
The objective of the methodology is to provide to farmers, agricultural consultants, owners and operators of biogas plants, to biowaste producers and processors, to experts in the field of soil reclamation and melioration, to investors and other interested parties on the concerned issues, the basic information about the potential at the combination of biogas production and biowaste hydrothermal carbonization. These options are evaluated on the basis of processing at accumulated energy intensity for the above combined processes and its comparison with conservative biogas production using the example biogas plant with installed electrical capacity of 800 kW. Part of the methodology is guided to evaluate the potential use of thermo- pressure hydrolysis unit as a device for digestate hydrothermal carbonization and other wastes in order to improve their performance, particularly in terms of employment in agriculture as highquality substrates for soil fertilization and for the purpose of soil carbon sequestration.

Anaerobic digestion of sludge from pulp and fodder yeast production
Řezáč, Jaroslav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
The thesis aims to identify suitable and in the locality available raw materials to a commnon fermentation with sludge from pulp and fodder yeast production in company Biocel Paskov a.s.. Introductory chapter briefly describes the mechanisms of penetration of the sludge itself. The following section deals with origin, chemical composition and properties of biogas. The factors affecting the production of biogas are described. A key part of this thesis is a performance of sludge fermentation test and selected mixed substrate. Acquired knowledge is evaluated and the optimum composition of input raw materials with regard to maximum, but also economic recovery of biogas selected. Further, on the basis of obtained data a rough draft of biogas station is done, icluding its energeic and economic balance.

Heat balance of anaerobic part of sewage treatment plants
Řezáč, Jaroslav ; Beňo, Zdeněk (referee) ; Pěček, Jan (advisor)
This thesis is focused on anaerobic stabilisation of sewage produced by sewage treatment plant. Mesophilic stabilisation was chosen for the sewage treatment plant . In the first chapter, main attention is dedicated to general treatise on sewage treatment plant. Anaerobic process of stabilisation, digestion tank and some of the medium are characterised there. Next chapter is dealing with thermal balance for selected version of sewage stabilisation. A proposal of digestion tank and thermal insulation is also made there. Further, heat exchanger, boiler and combined heat and power unit are projected.

Products based on hydrothermally treated residues from anaerobic
Usťak, Sergej ; Muňoz, Jakub ; Usťaková, Marie
The methodology aim is to provide the basic information about the products for the soil properties improvement based on hydrothermally treated residues from anaerobic fermentation to the farmers, agricultural consultants, owners and biogas plants operators, also to experts in the field of soil reclamation, investors and to other interested parties on the questions concerned. In the introduction, the methodology provides a basic overview about literary information regarding to coal similar materials, methods for their preparation, especially the methods of hydrothermal carbonization, their basic characteristics, possibilities and perspectives for their application in practice. Furthermore, the methodology describes the own results obtained during the research project usable in practice and provides their agrochemical, environmental and economic evaluation. The conclusion gives an overview of the potential application and the main use possibilities of the new products based on hydrothermally treated residues from anaerobic fermentation for the soil properties improvements and in particular for common agricultural fertilization and anthropogenic soils.
