What is aeration costing you?

Aeration is the single largest energy demand in biological wastewater treatment, and most of it runs whether the process needs it or not. Enter your blower figures to see the annual energy, cost and carbon behind it, the load worth reducing. Nothing is shared until you choose to.

This is an indicative estimate from the figures you enter, not a quote, and it states no saving. It sizes the energy aeration currently uses; what could be reduced is assessed and confirmed per site.

Why this is the load to look at

Aeration dominates the energy bill at a biological works because air is forced into the process continuously, often well beyond what the load actually requires. That makes it the single biggest controllable cost in treatment, and the first place to look when energy and carbon need to come down. How much of this load can be reduced depends on your process and is confirmed per site.
