Phosphorus Recovery from Sewage Sludge Ash
Šyc, Michal ; Kameníková, Petra ; Kruml, Matěj ; Sobek, Jiří ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Sewage sludge from wastewater treatment contains significant amount of phosphorus. Phosphorus recovery from secondary sources is nowadays increasing in its significance due to high consumption and rising price. The paper presents suitable methods for phosphorus recovery from wastewater, sewage sludge and sewage sludge ash. The preliminary results of lab-scale experiments on sewage sludge ash microwave enhanced thermochemical treatment are presented as well.

Recovery of Valuable Components from MSWI Bottom Ash
Šyc, Michal ; Kameníková, Petra ; Krausová, A. ; Baloch, T. ; Zach, Boleslav ; Pohořelý, Michael ; Svoboda, Karel ; Punčochář, Miroslav
Municipal solid waste incineration bottom ash contains wide range of valuable components, like ferrous and non-ferrous metals, rare earth elements, glass, ceramics and minerals for construction industry. The composition of bottom ash corresponds to incinerated waste composition and it is variable with respect to plant locality and season. The paper summarizes suitable methods for recovery of valuable components and presents the composition of bottom ash from ZEVO Malešice.

Co-combustion of Coal and Rubber Granulate in a Fluidized Bed
Pohořelý, Michael ; Šyc, Michal ; Krček, Martin ; Durda, Tomáš ; Kameníková, Petra ; Tošnarová, Markéta
The main aim of the study was to carry out test of the co-combustion of the coal supplied by Alpiq Generation (CZ), s.r.o. and the granules of rubber supplied by PATREM PIPE TECHNOLOGIES, s.r.o. in a fluidized bed of the ash supplied also by Alpiq Generation (CZ), s.r.o., provided that the blended fuel mixture contains at least 10 % by weight of the rubber granules.
Influence of Oxygen Partial Pressure in the Combustion Atmosphere on the Emissions and Efficiency of the Fluidized-Bed Incineration of Corn Straw
Durda, Tomáš ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Kameníková, Petra ; Jeremiáš, Michal ; Punčochář, Miroslav
This experimental study is focused on the corn straw incineration in a bubbling fluidized-bed reactor. The aim of this study is to compare the influence of oxygen partial pressure in the combustion atmosphere on the efficiency of the combustion process, and the emissions of undesirable pollutants (CO, NOx, SO2, N2O, and dust). The efficiency of the combustion process is compared on the basis of chemical unburned carbon (concentration of CO in the exhaust gas) and mechanical unburned particles (content of carbon in the solid form).
