Sewage sludge drying - theory and practice
Sirový, Martin ; Elsässer, Thomas (referee) ; Houdková, Lucie (advisor)
The thesis deals with sludge drying coming from biological sewage disposal plants from theoretical and practical points of view. The first chapter deals with the sewage disposal plant functioning and with sludge formation there. Furthermore sorts and properties of water treatment sludge are described here. In the second chapter the thesis points the look to the industry drying theory and then to the theory of sludge drying. The third chapter contains a list of current drying chambers convenient for sludge drying and their principles and description. The fourth chapter points to the present practice of sludge drying in the Czech republic. Prospects of the water treatment sludge drying are evaluated in the concluding part.

Sludge pretreatment and its further utilization
Němec, Jan ; Dlabaja, Tomáš (referee) ; Elsässer, Thomas (advisor)
The thesis deals with methods of pre-treatment (disintegration) of sewage sludge, which offers an opportunity for better operation of a waste water treatment plant. The introduction is aimed at sewage water and sludge dividing, and then at their characteristics. In this thesis a current state of sludge disposal within the reference to the legislature and how to divide the methods of disintegration is also marked. Afterwards a description of selected methods of sludge disintegration, their comparison and the applicability of thermal disintegration to pasteurization of sewage sludge is included.

Natural dewatering of sewage sludge of small producers
Mrvová, Michaela ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis is focused on measurements possibility associated with sludge dewatering, realized on technological wetlands. Focus of this thesis is the evaluation of evapotranspiration in wetland macrophytes, respectively - comparison of three measurements - in the sludge drying bed to the greenhouse facility, sludge drying bed without the greenhouse building and measuring the meteorological station at 2.0 meters above the ground. One of the goals is an automated system monitoring and regulating moisture conditions in sludge dewatering. The aim of the evaluation is completed dewatering equipment from an economic point of view.
