INVESTIGATION ON USABILITY OF BIOMASS ENERGY POWER PLANT ASHES FOR PATHOGEN REMOVAL FROM POULTRY MANURE

Abstract

In this study poultry manure and biomass ash at various ratio and temperatures were mixed and effects of hot biomass ash on removal of pathogens from poultry manure were investigated. Microbiological analysis carried out within the context of the study for pathogen examination (Termotolerant Coliform, Salmonella, E.coli Enterokok) in samples were performed by using ready media. According to the results obtained in the study, Salmonella and E. coli were not found in pure poultry manure and all other mixtures. However, 25x10(3) cfu/g Thermotolerant Coliform and 7.2x10(3) cfu/g Enterococcus were detected in pure poultry manure. The Thermotolerant Coliform and Enterococcus contents, initially detected on raw poultry manure were completely removed in applications using 50% biomass ash at all the temperatures. However, in applications of 200 degrees C and 250 degrees C, it was sufficient to use 40% of the biomass ash to completely remove both the Thermotolerant Coliform and Enterococcus contents. The results show that the hot biomass ash can be used to eliminate the pathogen microorganism content of poultry manure.
