Long Island wastewater treatment facility to increase energy efficiency with Atlas Copco screw blowers

Jan. 12, 2012 -- The wastewater treatment facility in the Town of Huntington, located on Long Island, NY, will take delivery of three new Atlas Copco oil-free, low pressure blowers during the first quarter of 2012.

Following a competitive bid, Huntington, selected Atlas Copco ZS75-K-900 low pressure screw blowers to reduce the energy usage of their aeration blower systems. This will decrease energy costs while enabling the wastewater plant to operate in a more efficient and environmentally friendly manner.

As part of the bid process, the Town of Huntington conducted an instrumented head-to-head test between the different manufacturers they were considering. During the test each machine operated simultaneously to determine conformity with stated requirements and to enable the Town's consulting engineer to record each machine's energy-efficiency level. The outcome of this test was pivotal in Atlas Copco becoming the successful bidder.

Air blowers typically represent up to 70 percent of the total electricity costs for municipal and industrial wastewater treatment plants. The ZS series of low pressure screw blowers average 30 percent more energy-efficient operation than conventional lobe blower technology and provide a continuous, highly-reliable, energy-efficient and 100 percent oil-free air supply.

"Since energy consumption typically represents 80 percent of the lifecycle costs of a blower, energy efficiency is always a serious consideration," said George Hubbard, low pressure sales manager - Eastern Region for Atlas Copco Compressors LLC. "Electricity rates on Long Island are higher than in many other parts of the country, so energy efficiency was a huge consideration for the Town of Huntington."
