Wastewater Blowers

Technical White Paper: Energy Efficiency Of Twin Screw Blowers Compared To Rotary Lobe Blowers In order to achieve a significant improvement in energy efficiency in the technology of air blowers for small volume flows, a technology step is needed. The step to achieve significant progress in energy efficiency in the low-pressure market is taken by introducing blowers using internal compression instead of external compression.

31% Energy Savings For Skanderborg Waste Water Treatment Plant With New 55 kW Atlas Copco ZS Blower
With a savings goal set at 25 % for the Danish waste water industry, optimizing all parts of the operation, so even the aeration, is of the highest importance. In 2011, The Skanderborg Waste Water Treatment Plant replaced one of its 75 kW lobe blowers with a new 55 kW Atlas Copco ZS screw blower and were able to reduce their energy consumption with 31%.
How To Select The Most Effective Blower Technology For Wastewater Applications
Given numerous variables when selecting an aeration blower system for wastewater applications, and equally numerous claims by technology providers, it is not surprising that confusion exists. Worse than confusion is the disappointment that results when a blower technology fails to perform as anticipated — and operating cost and efficiency benefits go unrealized.
Seepage Water Treatment: ZS Screw Blower Supplies Bacteria With Air In the seepage water treatment installation at the Münster waste management center, a screw blower from Atlas Copco supplies aerobic bacteria with air. The low-maintenance technology and the integrated frequency inverter were the deciding factors to use the energy-efficient ZS 55+ VSD.
Turbo Blower Technology Saves Money And Energy For City Of Adelanto WWTP
The City of Adelanto, Calif., wastewater treatment plant (WWTP) receives an average flow of 2.2 million gallons per day (MGD), but had a permit that allowed treatment of only 1.5 MGD.
