NEW CRITERIA FOR EVALUATING ADVANCED AND ENHANCED ANAEROBIC DIGESTION PROCESSES
Abstract:There is a proliferation of advanced anaerobic digestion (AAD) technologies under development and in demonstration status. Many of these technologies are 'add-on' systems that are placed before conventional high-rate anaerobic digesters. Public agencies are faced with process selection decisions on the new technologies, often with minimal information to make engineering decisions, an absence of extended track records of operation and maintenance, a lack of reliable process data, and a lack of reliable data on capital and operating costs for these recently-developed processes.
This paper reports upon the current status of an ongoing survey of such facilities and identifies trends in the selection and application of the AAD processes. This is intended as a progress report because of the rapid change under way in process development and application.
