THE EVOLUTION OF BIOSOLIDS HEAT EXCHANGERS
Abstract
Many municipalities are currently exploring options for upgrading existing conventional anaerobic digestion systems to produce Class A biosolids. Pasteurization of the biosolids prior to digestion is an EPA approved Class A process and can be achieved via simple retrofit. During the pre-pasteurization process, the biosolids temperature is elevated for a short period of time to meet Class A pathogen reduction requirements prior to volatile solids reduction in an anaerobic digestion system. The most important piece of equipment in pre-pasteurization systems is the heat exchanger. The focus of this paper will be on the evolution of Danish biosolids heat exchanger technology as used in pre-pasteurization systems.
