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.

Possibilities of elimination of residual ammonia content from technological water in power plants
Hajzler, Jan ; Bartoníčková, Eva (referee) ; Opravil, Tomáš (advisor)
This master thesis aims to study the possibilities of eliminating, or separation of ammonium shares from technological water of plants, where is introduced a secondary method of flue gas denitrification (SCR, SNCR). The need for elimination of ammonium shares arose after introduction of emission cap, which have been tightened since January 2015. The denitrification technologies were installed on devices that did not comply with the new limits. The theoretical part of the thesis deals with the description of combustion processes, as a fluid, and high temperature combustion of solid fuels, mechanisms of emissions and their reduction options. At the conclusion of the theoretical part is discussed the contents of the ammoniacal nitrogen in waters used in electricity and heating facilities to transport, or from which are separated by solid products of some processes such as desulphurization. There are also discussed some options for removal of ammonium salts from technological waters. Experimental part deals with finding appropriate method of determination of ammoniacal nitrogen, and the possibilities of its elimination by conversion to insoluble compound. Last but not least, the work deals with the evaluation of the sustainability of the proposed solutions. And as well as the real possibilities of their application in practice.
