The use of mechanical energy to inject air into water, to cause waste material in the water to absorb oxygen and decompose.
This fact sheet covers an overview of diffused and mechanical aeration, basic concepts of aeration design, the parameters and correction factors utilized in aeration design calculations, and aeration design considerations as well as solutions.
27 Φεβ 2002 · Written by three leading aeration experts, Aeration: Principles and Practice, covers the principles and practice of aeration, a unit process critical to the performance of activated sludge...
Mechanical aerators, such as surface aerators and brush aerators, aerate the surface of the water mechanically and promote diffusion of oxygen to water from the atmosphere. The concentration of dissolved oxygen in the liquid can be controlled by adjusting the speed of the rotors.
Mechanical aerators provide vigorous mixing and high oxygen transfer rates suitable for large-scale systems. Diffused aerators use fine bubbles to maximize surface area contact for improved gas exchange.
