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.

New DOE Air Compressor Regulations

By Bruce McFee, President, Sullivan-Palatek

The U.S. Department of Energy has initiated the efficiency regulation of oil-flooded rotary air compressors. This has the potential to cause a big change for the air compressor industry, as models from 35-1,250 cfm with pressures ranging from 75-200 psi (5.2-13.8 bar) will need to meet a minimum isentropic efficiency.
