Anglian Water To Use Atlas Copco ZS Blowers At Wastewater Treatment Re-Development Sites
Anglian Water, one of the UK’s largest water and wastewater treatment companies - operating over 1000 wastewater treatment works in the East of England - has chosen Atlas Copco’s low-pressure ZS blowers to supply air to the aeration diffusers at four of its wastewater treatment re-development sites.
A total of 22 Atlas Copco ZS90 rotary screw blowers will be installed at the sites in Colchester, Letchworth, Bedford and Flag Fen, near Peterborough as part of Anglian Water’s initiative to find innovative ways of reducing its energy costs.
Wastewater treatment plants use bacteria to break up waste which requires large quantities of air to be blown into aeration tanks. In a typical biological wastewater treatment plant, the blower system will account for up to 70% of energy usage. Anglian Water approached Hydrok, an aeration diffuser and IFAS specialist, about supplying submerged, high-efficiency, bubble aeration framework systems incorporating bio textile curtains and fixed bed media. These units improve the distribution of aeration air to maintain the desired level of dissolved oxygen within the wastewater containment system.
