Corgin spiral aerators
Renewi plc (formerly Shanks Waste Management) needed to replace the submerged venturi aerators for three sites in Argyll and Bute, Scotland. The company selected spiral aerators from Corgin, and installed eight aerators in December 2012 and a further one in December 2015.

3 x 11kW spiral aerators
3 x 5.5kW spiral aerators
Corgin's spiral aerators offer several key benefits, including:
Michael Harvey from Renewi plc said that the new spiral aerators from Corgin have proved to be far more successful than the original submerged venturi aerators which the company used previously. The aerators are much easier to remove for cleaning and any maintenance work, since a crane is no longer needed, and site telehandlers can be used instead.
Michael added: "They give adequate oxygen and mixing of the lagoons for the treatment of our wastewaters and from our landfill sites, which ties in with the Renewi plc outlook for the future 'waste no more'."
