PERSPECTIVE METHODS OF SEWAGE SLUDGE UTILISATION FOR ENERGY PRODUCTION
Elsässer, Thomas ; Klemeš,, Jiří (oponent) ; Žaloudík, Petr (oponent) ; Stehlík, Petr (vedoucí práce)
This thesis on the processing of sewage sludge in waste to energy applications contains a description of sludge material properties (density, specific heat capacity and dynamic viscosity), and is, in its main chapters, devoted to sludge disintegration for improved dewatering and the experimental study of emissions produced in incineration, where the influence of alkali addition was examined. The incineration of dried sludge was done in a fluidized bed reactor and the production of air emissions and distribution of heavy metals was studied. The thermo chemical disintegration of stabilized sewage sludge, elaborated in the second main chapter, aims at reducing the water content of sludge after dewatering. Experiments conducted in laboratory scale aimed at identifying a suitable temperature level, required dosage of chemical agent. In the following, a basic economical evaluation is described, where the savings are determined from savings in sludge disposal.
