Aeration Energy Auditing
Systematic measurement of blower energy use against actual oxygen demand to identify savings opportunities.
An aeration energy audit compares metered blower power draw against calculated actual oxygen demand (from BOD load and MCRT) to quantify current efficiency.
Common findings include oversized blowers running inefficiently at low turndown, fouled diffusers requiring excess air to hit DO targets, and manual control leaving unnecessary safety margin.
A documented before-and-after audit is often required to justify capital spending on blower upgrades, DO-based control retrofits, or diffuser replacement programs.
