Temperature plays a crucial role in the growth and survival of bacteria in wastewater treatment plants. The suitable degree of temperature for bacterial growth is typically between 20-35°C. If the temperature is too high or too low, it can negatively impact the efficiency of the treatment process.
If the temperature is too high, it can lead to a decrease in dissolved oxygen levels, which can harm aerobic bacteria that are responsible for breaking down organic matter. To modify this, cooling systems such as evaporative cooling towers or heat exchangers can be used to lower the temperature.
On the other hand, if the temperature is too low, it can slow down bacterial activity and prolong treatment times. In this case, heating systems such as boilers or heat pumps can be used to raise the temperature.
It’s important to maintain a consistent and suitable temperature range in wastewater treatment plants to ensure optimal bacterial growth and efficient treatment processes.
