A mesophilic anaerobic digester typically operates at a temperature range between 85 to 105 degrees Fahrenheit, with the ideal condition around 90 to 95 degrees Fahrenheit being optimal for the activity of mesophilic bacteria. This temperature range fosters the growth of microorganisms that effectively break down organic matter in wastewater, resulting in higher rates of biogas production.

Mesophilic conditions not only allow for optimal metabolic activity but also help in maintaining stability within the digester. At these temperatures, the bacteria that thrive are able to efficiently digest the organic materials and produce biogas, primarily methane and carbon dioxide, as byproducts. Furthermore, operating outside this ideal temperature range can slow down the digestion process and reduce biogas output significantly.

Therefore, the selection of the temperature range of 90 to 95 degrees Fahrenheit aligns perfectly with the operational standards for mesophilic anaerobic digesters looking to maximize biogas production.
