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.

Reduction of nitrogen oxides in flue gas on special filter materials
Sirový, Martin ; Jecha, David (referee) ; Jedlička, Filip (advisor)
This thesis deals with the reduction of oxides of nitrogen (NOx) which are part of the exhaust gas combustion devices. The focus is on reduction of NOx by selective catalytic reduction (SCR) and catalyst filtration. The first part of this work deals with the formation of NOx, their hazards and related legislation. The following is an overview of the available technologies to reduce NOx in the flue gas and comparison of this methods. The following section describes the experimental catalytic filtration unit INTEQ II, where the first real experiment selective catalytic reduction of NOx with ammonia was realized. We have verified the operability of the experimental units and achieve up to 80% efficiency SCR. The final section describes the progress of the experiment and its results. It is recommended a few minor adjustments to improve stabile operation of unit INTEQ II.
