The Business Case for Air Compressor Rentals and Air-Over-the-Fence

By Matt Piedmonte, Vice President and General Manager, Americas, Aerzen Rental Solutions

There is no single right approach to putting the necessary volume and pressure of air in the pipe to meet production needs. There is a place for purchasing assets, there is a place for renting assets and there is a place for an AOF contract. Just as the business models around these assets change, so do the needs of an industrial plant. This article aims to explore these options and explore some of the pros and cons associated with different methods.

Turbo Blowers Generate Significant Energy Savings at Victor Valley Wastewater

By Robert Lung for the U.S. Department of Energy Better Plants Program

A replacement strategy for air compressors and blowers integrated into a system-level approach towards energy efficiency can deliver significant energy savings and optimize equipment performance. At the Victor Valley Wastewater Reclamation Authority, a blower replacement project yielded annual energy savings of more than 928,000 kWh and $98,000 in energy costs, while improving the reliability of its secondary treatment process. In addition, the agency qualified for important incentives from its electric utility — significantly improving the project economics and resulting in a 2.94-year payback.

High Speed Bearing Technologies for Wastewater Treatment Applications

By Aleksandra Irving PE and Joseph Ibets PE, The Spencer Turbine Company

High speed bearing technology is applicable for aeration blowers operating at much higher speeds than the typical 60Hz, 3600RPM for cast multistage units. High Speed Turbo (HST) units are usually single stage (though some utilize multiple cores) and rotate from 15,000 to 50,000RPM. At such high speeds, standard roller bearings cannot offer the industry standard L10 bearing life. Two types of bearing technologies have come to dominate the wastewater treatment market for these types of machines: airfoil and magnetically levitated. Often the two technologies are compared as equals, however, in many significant ways they are not.

O₂ Automation: The Future of Bubble Mixing?

Compressed Air Best Practices® Magazine interviewed Kris Drewry from O₂ Automation and Pulsed Hydraulics Inc.

We have industrial accounts where we mix chemicals and acids. Our favorite is blending wine and spirits using compressed nitrogen. The old way to blend was to use “air rousing.” This was done by installing rows of perforated pipes in the bottom of the tank and attaching an air pipe to this grid. Since the typical mixing cycle was 45 minutes, copious amounts of air and energy were used.

Aeration Energy Offers Opportunities to Save

By Jess Burgess, Consortium for Energy Efficiency

Aeration systems at wastewater treatment facilities present significant, cost-effective energy savings opportunities. Aeration—the introduction of air into the wastewater stream to support anaerobic bacteria and mixing—is a key function at the majority of wastewater treatment facilities in North America. Aeration accounts for 25-60 percent of total energy consumption at wastewater treatment facilities , and a significant piece of operating budgets sector-wide.

Adaptive Control for Low Pressure Wastewater Treatment Air Systems

By Roy Stuhlman, Kaeser Compressors, Consultant and an instructor for the Compressed Air Challenge® and Stephen Horne, Kaeser Compressors for the Compressed Air Challenge®

In recent years, there have been many changes in wastewater treatment. Most modern processes control three cycles: DO, NH4, and NO3, and all of the processes require high volumes of air. Undeniably, the low pressure air system uses more electrical power than the rest of the wastewater treatment plant combined. The blower packages in these systems can be equipped with low noise enclosures, fixed speed or variable speed drives, and can include all the instrumentation needed for self-protection.

Energy Saving Opportunities in Blowoff Applications

By Ted Clayton, Kaman Industrial Technologies

Assessing payback on engineered air nozzle and blower upgrades There are a variety of means factories can use to remove or “blowoff” moisture from a package. Open tubes or drilled pipe are often viewed as simple low-cost methods. However, there are considerable drawbacks to these approaches, most notably – increased operating expense. While they may be convenient and inexpensive in the short term, these approaches often cost 5-7 times more to operate than preferred alternatives.
