What is the ideal temperature range for activated sludge treatment processes?

The ideal temperature range for activated sludge treatment processes is 20-30°C. This temperature range is optimal because microbial activity, which is crucial for the treatment process, is generally highest within these values. At temperatures around 20-30°C, microorganisms that break down organic matter are fully active and efficient, leading to better degradation of pollutants in the wastewater.

As the temperature drops below this range, microbial metabolism slows down, which can lead to decreased treatment efficiency and an accumulation of pollutants. Conversely, temperatures that exceed 30°C can also be detrimental, as excessive heat may inhibit microbial activity or even kill some microorganisms, disrupting the balance of the activated sludge process. This balance is key to maintaining the health of the microbial community responsible for treating the wastewater effectively.

In summary, the 20-30°C range supports optimal microbial function, enhancing the efficiency of the activated sludge treatment process.
