Deploying Drop-Over Sound Enclosures To Manage Excessive Noise

For wastewater treatment sites which were once far from housing developments, and are now being encroached by new developments, retrofit sound enclosures can lessen the noise level associated with the operation of your wastewater treatment equipment.

For those sites which are experiencing this type of situation, HPA provides the solution: Retrofit Sound Enclosures, whether individual enclosures, or entire buildings.  The following images show an initial deployment where no homes existed near the perimeter of the wastewater treatment plant, and then years later, housing developments began cropping up, and the residents complained about the noise level.  By deploying HPA’s sound enclosures, the problem was eliminated and even allowed the equipment to be better protected from the weather while extending the life of the blower packages.

In examining this situation in greater detail, you can see these advantages in this single building:

• We incorporated a pair of doors for easy access and maintenance.
• We placed thermostatically controlled air vent fans above each of the three packages to manage the air flow into and out of the enclosure.
• So that no piping needed to be dismantled or rerouted, we incorporated flashing so that the enclosure could be built around the existing piping.
• Additional electrical connections to power the vent fans and lights were made possible from existing lines which terminated in the blower packages.
• We can also relocate gauges and digital read-outs onto the side of the enclosure(s) to simplify the effort associated with reading these items.

The bottom line: HPA gets it done.  No gimmicks, no canned solutions.  Just smart, tough, insightful engineering building custom solutions to meet your exact needs.

Direct-Drive Blower Technology: A Smarter, More Reliable Choice for Wastewater Treatment

For over a century, V-belt technologies have been the standard in municipal and private wastewater treatment operations—reliable, familiar, and effective. But in the last decade, direct-drive technology has reached a level of reliability and performance that makes it a superior, forward-looking alternative.

Why Switch to Direct-Drive?

Here are key advantages that make direct-drive systems the smarter investment:

• No Overhung Load – Direct-drive systems eliminate overhung loads on shafts, sheaves, and bearings, significantly reducing wear and tear. This extends component life and system longevity.
• Energy Efficiency and Cost Savings – Direct-drive systems consume less energy, leading to annual savings ranging from hundreds to thousands of dollars.
  • Ask HPA for a custom cost profile analysis to see your potential savings.
• Improved Operational Efficiency – Expect a 7–10% increase in efficiency over belt-driven systems, which translates to lower operational costs and better performance.
• Lower Maintenance Requirements – Say goodbye to frequent belt changes, tension adjustments, and replacement part purchases. Direct-drive systems dramatically reduce maintenance demands.
• Built-in Misalignment Tolerance – Our direct-drive units accommodate up to 4% misalignment between blower and motor.
  • HPA ensures precision alignment during manufacturing—meeting the same standards as power plant systems—and provides documentation to validate this accuracy.

Risk Avoidance in Action

Transitioning to direct-drive technology helps you proactively avoid common failure points:

• Prevent bearing failures caused by overhung loads
• Avoid overheating and damage from broken belts while motors continue running
• Reduce the risk of non-compliance penalties due to unexpected blower outages when no air is being pushed into your wastewater treatment operations

The Bottom Line: Today municipalities face growing pressure to improve services, reduce costs, and optimize operations. Upgrading to direct-drive blower systems is a practical, risk-reducing investment that pays for itself through operational stability and long-term savings.

Let HPA Help You Make the Shift

Trust Hardy Pro-Air Systems & Service to deliver a direct-drive solution that stabilizes your operations and enhances your confidence in system performance.
