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.

Treatment of sludges from water treatment plants
Mach, Michal ; Kučera, Tomáš (referee) ; Biela, Renata (advisor)
The bachelor thesis focuses on the methods of disposal and the use of water sludge generated in the treatment of water used nowadays. The work is divided into a theoretical part and a practical part. The theoretical part is focused on the basic properties of sludge, its composition and getting acquainted with technological solutions leading to its treatment and disposal today. The practical part introduces the specific water treatment in the Czech Republic, and how specifically these treatment plants deal with the issue. Based on the practical part, it is possible to present more about how are these problematics in fact mostly solved.

Technologie zpracování a likvidace neutralizačních kalů z povrchových úprav kovů
ČSUP, o.z. Uranové doly Dolní Rožínka ; Bořecký, Dalibor ; Pall, Milan ; Přikrylová, Jana ; Šťastná, Miroslava ; Špaček, Václav ; Macura, Jan ; Vejnar, Pavel ; Tomášek, Josef ; Neterda, Vladimír
Zpráva obsahuje výsledky laboratorního a poloprovozního ověření technologie zpracování neutralizačních kalů. Je diskutována otázka vzniku neutralizačních kalů, surovin používaných při jejich likvidaci, složení kalů a jejich nebezpečnost. Dále je popsán laboratorní výzkum technologie zpracování bohatých kalů.
