What is the effect of not cleaning aeration tank diffusers regularly?

Not cleaning aeration tank diffusers regularly can lead to uneven air distribution. Over time, the diffusers can become clogged with biofouling, sediment, and other debris, which impedes their ability to efficiently release air into the water. This results in some areas of the aeration tank receiving more oxygen than others, leading to imbalances in the oxygen levels necessary for effective biological treatment processes.

Uneven air distribution can significantly affect the performance of the aeration system, as it may cause some portions of the tank to be less effective in supporting the growth of aerobic microorganisms. As these microorganisms rely on a stable supply of oxygen for their metabolic processes, any disruption can hinder the overall treatment efficiency, potentially leading to subpar wastewater quality. Regular cleaning of the diffusers helps maintain an even distribution of air, which is essential for optimal biological activity and treatment performance.
