Spent Grain Pumping
Hrubý, Jaromír ; Medek, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
This master´s thesis deals with the utilization of spent grains. It briefly introduces the issue of hydraulic transport settling and non-settling mixtures, pumps, piping design and technology designed for a particular case. After these chapters, the calculations of parts of the technology utilization spent grains follow.

Sludge Pumping on WWTP
Fadrný, Tomáš ; Medek, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
This diploma thesis deals with the best solution design for a sludge fitting, especially focusing on the right choice of pumps for the waste water treatment plant in Prostějov. The pumps were selected for a circulation pipeline, which heats up the sludge. Several measurements were carried out in order to determine the statistical evaluation of the properties of the pumped medium. The figures gained were used to calculate pressure losses.The diploma thesis is divided into two parts. The first part provides a theoretical analysis of the problem and the second part presents the results and subsequently the reasoning for the new selection of pumps in order to change the WWTP technology from the mesophilic to the thermophilic sludge digestion. The test records describing the testing of the individual samples of the pumped sludge are attached.

Information Systém Utilization in the Sphere of City Management
Šíma, Kamil ; Boráň, Jaroslav (referee) ; Novotný, Pavel (advisor)
Subject of my Bachelor´s work is problems of treatment of waste in cities with a population over 50 000 inhabitants. It especially includes ways of salvage of sorted waste and subsequent utility of secondary raw materials, which are situated in municipal waste and examples of systems of salvage and bringing together. The work also includes indicative data of quantity of produced and sorted waste in the city. With using information which are included in the bachelors work, which was obtained mostly with using information systems, is observed by Plan of waste economy of the city with taking scout of Plan of waste economy of region focusing on salvage of separated waste.

Dependence of Sludge Thermal Pre-treatment on its Dewatering
Žerava, Zdeněk ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
The first part of the thesis is focused on the problems related to sludge and evaluates sludge disposal from waste treatment plants. The thesis mentions factors influencing method selection of sludge disposal as well as it compares sludge disposal in the Czech Republic and in the other states of the EU. It describes a complete waste treatment line and sludge disposal in the area of sludge treatment and disposal. It deals with sludge disintegration and describes the most effective methods of disintegration. The second part of the thesis describes an experimental part of disintegration of waste treatment sludge. An experiment was conducted in the school laboratory in a way of thermal disintegration in the double-surface pressure tank. The disintegration was conducted to temperatures of 60 °C, 90 °C, 120 °C, 150 °C, and 180 °C. We monitored dependence of the sludge dry residue content on disintegration temperature as well as content of suspended solids in liquid fraction (FUGAT). It was possible to choose optimal temperature of disintegration in accordance with processed results.

Sludge Utilisation from Pulp and Paper Plant
Zemanová, Kateřina ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
The contens of diploma thesis is description of paper and pulp production and analysis of contemporary problems with disposal of sludges rising on industrial waste water treatment plant. Accent is focuses on description of waste water treatment technique, characteristics of rising sludge and the ways of his liquidation in particular plant for pulp production. Fundamental part of this project is evaluation of power and economics balance of current sludge technology in company Biocel Paskov a.s. and suggested sludge management technology. Balances are based on data gained from measurement in laboratory and on data gained from literary research.

Design of Sludge Disintegration Unit
Brtna, Filip ; Beňo, Zdeněk (referee) ; Boráň, Jaroslav (advisor)
The target of the first part of this diploma thesis is focused on the problems relating to the sludge production from the wastewater treatment plant and subsequent sludge treatment. In this thesis complete process of the wastewater treatment is described. Predominantingly is described the process in digestion tanks, therefore stabilization process, whereas the paper is focused on sludge pre-treatment (disintegration) of waste activated sludge before stabilization. The second part of this thesis is focused on the design of the disintegration unit for the wastewater treatment sludge in assist with experimental data. According to measured and fixed parameters the unfired pressure vessel has been designed. On the vessel has been further realized the strength calculation, the heat balance and the economic balance.

Kitchen Waste Fermentation
Dlabaja, Tomáš ; Jícha, Jaroslav (referee) ; Boráň, Jaroslav (advisor)
Biodegradable waste is a significant type of waste, which includes kitchen waste from restaurants, catering establishments and kitchens as well. This work evaluates a waste production in the Czech Republic and compares it with a waste production of other European countries. It provides a brief search through legislation and analyzes present development, going from simple disposal of material to energetic and material utilization. New laws has established stiffer requirements for the treatment of dangerous biowaste including kitchen waste. Under all these changes benefits of the most suitable ways of waste treating are analyzed. Part of the work is a laboratory experiment of the biogas yield, which verifies theoretical assumption of kitchen waste utilization at anaerobic fermentation. In conclusion the economy calculation of such manufacturing plant is done.
