Innovation in sludge treatment can be a challenging process. A newly developed or innovative sludge disinfection process not only has to function in accord with prevailing federal, state and local regulations, but must adhere to ever increasing restrictions imposed by the regulatory authorities. The entire process, from development and testing to implementation, must be well documented in order to be approved by the US Environmental Protection Agency's (EPA's) Pathogen Equivalency Committee (PEC). Two processes have recently gone through this approval process, the BCR Neutralizer™ Process and the Schwing Bioset™ Process. The Neutralizer Process is a batch process which utilizes chlorine dioxide and nitrous acid to treat waste activated sludge. The Schwing Bioset Process is a continuous plug-flow advanced alkaline process that uses a closed-system to disinfect dewatered residuals. This paper will detail the steps involved in the approval process, including the time and costs involved along the path to Process to Further Reduce Pathogens (PFRP) approval.
