In a thermophilic digester, what is the temperature range considered optimal?

In a thermophilic digester, the optimal temperature range is crucial for the efficient processing of organic material through microbial activity. The temperature range of 122-140°F is ideal for thermophilic bacteria, which thrive in higher temperatures compared to mesophilic bacteria. At these elevated temperatures, the digestion process is enhanced, leading to more rapid breakdown of organic matter, increased biogas production, and effective pathogen reduction.

Thermophilic digestion is particularly advantageous for waste treatment facilities handling high-strength waste or requiring space-efficient systems, as the higher temperatures accelerate the degradation processes. Maintaining temperatures within this optimal range supports the metabolic activity of thermophilic microorganisms, ensuring that the digestion system operates efficiently and effectively.
