What is the typical temperature range for a thermophilic digester?

• A. 14-68°F
• B. 59-113°F
• C. 110-176°F
• D. 140-200°F

Answer: (C)

The typical temperature range for a thermophilic digester is between 110 and 176°F. This range is significant because thermophilic conditions facilitate the breakdown of organic matter by specific bacteria that thrive in higher temperatures. Operating within this temperature range promotes more efficient digestion of waste, leading to faster decomposition and improved production of biogas. In thermophilic digestion, the elevated temperatures help to reduce pathogens and produce a more stabilized end product. The other temperature ranges do not align with the characteristics of thermophilic digestion. For instance, the lower ranges would correspond to mesophilic digestion, which operates at lower temperatures and is suitable for different microbial populations. Understanding these temperature ranges is crucial for optimizing wastewater treatment processes and ensuring effective waste breakdown.
