Supplying dissolved oxygen typically uses between 40 - 60% of the electricity used in waste water treatment. Many facilities have enough aeration capacity for maximum loading design which well above average daily loadings. In the short run managing aeration by optimizing blower or surface aeration operation can cut electricity use. However, in many cases we rely on the diffusers & mechanical aerators for mixing as well as dissolved oxygen. So while we may have enough dissolved oxygen but not have enough mixing to keep biological solids suspended. Optimizing both aeration and mixing can help reduce utility costs. Here is how to optimize aeration:
