The Vaughan Scumbuster®virtually eliminates the effects ofa scum blanket and prevents itfrom reforming byhomogenizing andconditioning through arecirculation nozzle. This typeof mixing allows digesters toregain their design capacity,extends the time betweencleanouts and generates moremethane gas. The Vaughan Scumbusteroperating with the Vaughan chopper pump on digester recirculationhas proven successful not only to eliminate heat exchangerclogging, but also to replace other failed digester mixing systems.
