- Process mixing for wastewater and industrial applications including Anaerobic Digesters, Storage Tanks, Etc.
- Vaughan Chopper Pump to enhance volatile solids destruction while ensuring reliable operation of the system.
- Dual rotational mixing to provide even distribution of solids throughout the tank.
Vaughan’s Rotamix® system is today’s most cost effective means of mechanical hydraulic mixing, consisting of an engineered arrangement of floor mounted nozzles fed by a Vaughan® chopper pump. Using custom engineering software, each application is analyzed and sized by Vaughan in order to achieve the desired mixing effect. The Rotamix system may be applied in circular, rectangular, oval tanks and basins and other unique process configurations such as egg-shaped digesters, CSO tunnels and pump stations.
The Concept
The Rotamix system incorporates several basic principles of physics and hydraulics, including uniform field of flow, vertical field of flow, induced flow and surface contact. Combined together, this unique mixing system optimizes solids contact due to the homogenous state.
Dual-Zone Mixing
- Uniform field creates velocity at outside perimeter
- Vortical field creates velocity at center
- Uniform & Vortical fields create "Dual-Zone Mixing"
- Higher velocities induce entrained fluid
- Reduced solids size from Chopper Pump enhances solids contact
- Increased VSR results in increased gas production
- Vaughan reliability & over 50 years expertise as a solids handling specialist
- Process expertise in understanding each application
- Engineering support using state of the art CFD software
- Over 600 systems installed since 2000
- Process testing successes
- Chopper Pump provides reliable operation
- Dual nozzles provide multiple discharge points, reducing piping costs while evenly distributing sludges
- Actual Sludge rheologies are used to produce the most accurate analysis and design
