Vaughan Rotamix replaces outdated gas mixing equipment at Chapel Street WWTP in Tauranga
Plagued by poor mixing and foaming problems, the Tauranga City Council required a new approach that would provide better mixing for their two 15.5 metre diameter digesters. Pump Systems was called on to design and supply two Rotamix nozzle mixing systems to replace the outdated gas mixing equipment and to provide improved overall active volume mixing. Unlike recessed impeller or screw impeller pumps, the unique chopping action of the Vaughan chopper pump ensures reliable long term performance by continuously preconditioning incoming sludge and thereby eliminating the risk of clogging.
