The Vaughan "Scumbuster" virtually eliminates the effects of a scum blanket and prevents it from reforming by homogenizing and conditioning through a recirculation nozzle. This type of mixing allows digesters to regain their design capacity, extends the time between cleanouts and generates more methane gas.

• Easy above-deck access to valve and nozzle operators
• Manual or fully automated operation available

The Vaughan Scumbuster operating with the Vaughan chopper pump on digester recirculation has proven successful not only to eliminate heat exchanger clogging, but also to replace other failed digester mixing systems.
