What is the main reason for defective operation in an aeration tank?

A clogged diffuser plate is a primary concern in the operation of an aeration tank because it directly affects the efficiency of air distribution necessary for effective aeration. In an aeration tank, air is injected into the wastewater to promote the growth of aerobic microorganisms, which help in breaking down organic materials. If the diffuser plates are clogged, it can lead to inadequate oxygen supply, creating an environment where aerobic bacteria cannot thrive. This can drastically impact the overall treatment process, as the microorganisms rely on oxygen to facilitate the breakdown of sewage.

Furthermore, insufficient oxygen levels can result in higher concentrations of pollutants in the effluent, leading to poor water quality and potential violations of discharge permits. Maintaining the operation of diffuser plates is crucial for ensuring proper air flow and enhanced treatment efficiency, highlighting why this issue is often deemed a main reason for defective operation in an aeration tank.
