What is the typical temperature range for effective aerobic treatment in wastewater facilities?

In aerobic treatment processes, microorganisms use oxygen to break down organic matter in wastewater. This biological activity is highly sensitive to temperature, which affects metabolic rates and overall treatment efficiency.

The typical temperature range for effective aerobic treatment is between 20°C and 37°C. Within this range, microbial activity is maximized, leading to efficient breakdown of organic materials. At temperatures below 20°C, microbial activity begins to decline, which can slow down the treatment process and reduce the effectiveness of the aerobic treatment. Conversely, temperatures above 37°C can stress the microorganisms, often leading to decreased performance and potential inhibition of biological processes.

This range is supported by numerous studies and operational guidelines in wastewater treatment that focus on maintaining ideal conditions for aerobic organisms to thrive and effectively treat wastewater.
