What should wastewater treatment operators monitor to ensure proper operation of aeration tanks?

Monitoring diffuser cleanliness is crucial for the proper operation of aeration tanks because diffusers are responsible for delivering air to the wastewater. Clean diffusers ensure that air is evenly distributed throughout the tank, allowing for effective oxygen transfer to the microorganisms that break down organic matter. If the diffusers are clogged or dirty, it can disrupt the air flow, impairing the aeration process and leading to inadequate biological treatment. This can result in poor effluent quality and hinder the overall efficiency of the treatment system. Therefore, maintaining the cleanliness of the diffusers is essential for the optimal functioning of the aeration tanks.
