INACTIVATING ANIMAL PATHOGENS WITH THE ALKALINE HYDROLYSIS TECHNOLOGY: ENVIRONMENTAL ISSUES ASSOCIATED WITH CONTROLLING THE SPREAD OF ANIMAL DISEASE
Abstract:The recent international emergence of Bovine Spongiform Encephalopathy, BSE (“mad cow disease”) and Foot-and-Mouth Disease has highlighted the importance of effective pathogen inactivation in controlling the spread of animal disease. Of particular importance is the ability of carcass disposal methods to destroy pathogens. Alkaline Hydrolysis, a relatively new and innovative technology, is increasingly being used as an alternative to incineration for this purpose. The technology, which is in use at the University of Florida and planned for the destruction of over half a million pounds annually of animal carcasses at Cornell, has been demonstrated to destroy carcass waste and inactivate pathogens effectively, but creates a very high strength wastewater with corresponding management challenges. This paper will discuss the pathogen inactivation mechanisms of the Alkaline Hydrolysis process, wastewater effluent characteristics and impacts on wastewater treatment, including disinfection and treatability issues.
