Rotamix Advantages

Cost Savings

When compared to conventional mixing systems, the Rotamix system can save up to 60% in combined capital, operation and maintenance costs.

Complete Mixing

Multiple nozzles allow effective mixing energy distribution, eliminating the need for rotating nozzles. By using the Vaughan chopper pump, surface area and subsequent organic breakdown is maximized.

Energy

  • Ability to intermittently mix tanks after long periods of storage, offering power savings
  • Allows intermittent operation of conventional process systems, reducing energy costs

Operation

  • Fixed dual rotational pattern makes rotating nozzle designs obsolete
  • Vaughan Chopper pumps virtually eliminate problems with fibrous material and other debris, while ensuring pumps remain clog-free
  • Efficient mixing optimizes chemical consumption in sludge dewatering applications
  • Operates without liquid level dependency
  • Meets or exceeds high rate digester designs

Minimal Maintenance

  • No scheduled nozzle assembly maintenance required
  • No rotating equipment within the process
  • Reduces confined space entry into tanks for maintenance

Capital

  • Ability to mix multiple tanks, using only one pump
  • Ability to fill, mix and transfer using only one pump
  • No access walkways, platforms or hoists required
  • Complete installed Rotamix system typically costs less than equipment alone for other types of mixing systems
  • Potentially reduces cost of aeration equipment
  • Easily retrofits into existing tanks
  • Ability to work with flat floor design reduces construction costs
