N/A 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. 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.

Municipal Wastewater Applications

N/A 1. Raw Sewage - Lift stations, CSO facilities, headworks, prisons, hospitals, restaurants.
2. Screening / Septage - Raw concentrated solids including rags, plastics and hair.
3. Clarifier Scum Pits - Primary or Secondary scum without plugging or air binding.
4. Sludge Transfer - Eliminates "roping" and clogging in clarifier underflow to thickeners.
5. & 6. RAS / WAS - Continuously conditions Return and Waste Activated Sludges.
7. & 8. Thickened Sludge / Digested Sludge Transfer - Handles high sludge consistencies.
9. Digester Mixing - Rotamix® system conditions and mixes in a dual-zone rotational flow pattern.
10. Digester Recirculation - Eliminates heat exchanger clogging while conditioning sludge.
11. F.O.G - (Fats, Oils, and Greases) - Uses organic waste to enhance methane production
