The ventilation system is a critical element in biological wastewater treatment plants. The purpose of this system is to provide the necessary oxygen to the microorganisms present in the wastewater, in order to carry out the biological cleaning process.
The aeration system usually consists of air ducts and various machines that provide the possibility of air circulation inside the softened sludge. During the aeration process, the wastewater is agitated, allowing oxygen to be recycled and distributed to the microorganisms needed to carry out the biological degradation of pollutants.
Proper management of the aeration system is essential to ensure the efficiency of the biological process and ensure the quality of the final treated effluent.
