The blowers at your WWTP can account for up to 60% of the total energy consumption. But is it possible to reduce that energy use without investing heavily in new blowers, new equipment, new piping, contractors, or extended downtime?

Blowers are originally sized based on factors such as basin dimensions, diffuser count and zoning, system pressure losses, and projected population growth for the city they serve.
However, conditions change over time:

• Operators and maintenance teams may reduce pressure losses, improving overall plant efficiency.
• Actual city development may differ from the original forecasts.
• Basins may be added, removed, or reconfigured.

As a result, your blower may now be oversized or undersized for the current operating conditions.

In this session, I will explain what can be done to correct this.

Rather than replacing entire blower units and purchasing new equipment, you can revamp the existing blowers. By upgrading internal components, the blower’s original design can be modified to match today’s requirements and significantly improve efficiency.

This approach minimizes both investment and downtime compared to a complete equipment replacement. Existing piping remains in place, and a newly optimized blower can be delivered in less than a week.

A greener future does not always require brand‑new equipment. By re‑engineering what you already have, you can substantially reduce your plant’s energy consumption and improve operational performance.
