What is the typical operational temperature range for biological treatment processes?

The typical operational temperature range for biological treatment processes is indeed around 25 to 30 degrees Celsius. This temperature range is optimal for promoting the activity of microorganisms that are essential for breaking down organic matter in wastewater treatment.

At these temperatures, microbial metabolism is generally maximized, allowing for efficient treatment processes. Temperature plays a critical role in influencing the biochemical reactions carried out by microorganisms; they thrive at this range, facilitating rapid digestion of waste and effective removal of contaminants.

In lower temperature ranges, such as 10 to 15 degrees Celsius or 15 to 20 degrees Celsius, microbial activity can significantly slow down, which may lead to increased treatment times and less effective processing. Conversely, at higher temperatures, like 35 to 40 degrees Celsius, there is a risk of thermal stress on the microbial populations, which can lead to decreased performance or even die-off of sensitive species.

Maintaining the process within the optimal range of 25 to 30 degrees Celsius helps ensure that the biological treatment processes are both efficient and effective in removing pollutants from water.
