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.

Sensors for decentralized system of water purification
Plotěný, Miroslav ; Mácha, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
Main task of the Master Thesis is to study and propose appropriate sensors that can monitor standard operations of small waste treatment plant. This small plants may replace one big central waste water treatment plant, minimizing interference with the human factor and thus reducing the cost of its operation. Master Thesis deals with the sensors for level measurement, air flow, identifying the operator and others. The most important parameter is the quality of drainage water, which can be derived from the amount of ammoniacal nitrogen. This work discusses the possibility of continuous measurements of ammoniacal nitrogen in water and try to select the optimum solution. At the end of the work is carried out experimental measurements are selected ammonia probe to verify the practical features.
