As part of a major upgrade works at the Christies Beach WWTP in South Australia, Pump Systems designed and supplied three Vaughan Rotamix Process Mixing Systems for mixing sludge in the plant's three 21.3 metre diameter anaerobic digesters. Two of the Rotamix systems would replace older gas mixing equipment in existing Digesters 1 and 2, while the third Rotamix system would be installed in a newly constructed identical Digester.
