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%.

Up to 70 % of the energy consumed by a WWTP (Waste Water Treatment Plant) consists of low pressure aeration of the waste water, why savings in this part of the process is of paramount importance.  – Atlas Copcos’ ZS screw blowers are on average 30 % more energy efficient than lobe blowers. This hasbeen proven by independent tests by TÜV and by WWTP’s in Scandinavia. Skanderborg WWTP had problems with their aeration using lobe blowers so we suggested that they would try the Atlas Copco ZS blowers, says Flemming Broksø Sales Engineer Oil-free Air at Atlas Copco Compressor Technique Scandinavia.
