Northumbrian Water opts for energy-efficient ZS screw blower

ZS screw blower at Northumbrian waste water treatment plant

Northumbrian Water, a leading provider of water and sewerage services in the North East of England, has chosen Atlas Copco screw blower technology to help reduce energy consumption and minimise service costs at its sewage treatment works in Newton Aycliffe, County Durham. Read more about their story here.

Atlas Copco ZS screw blowers helped us improved with 20% on energy usage, so we decided to replace all our conventional lobe blowers with Atlas Copco screw blowers.

Aquafin chose ZB centrifugal blower for their total cost of ownership approach

Aquafin, a company operating waste water infrastructure in Belgium, considered the total cost of ownership in the application of wastewater treatment. It was also important that the solution spoke not only to the financial aspects but also its environmental impact. With their sights set on the big picture, Atlas Copco was able to support their vision.
