We have several niche process solutions that save energy, increase output and cut cost.




The Raptor 4002 delivers advanced biological waste treatment to lagoons.

Our directional aeration and mixing solution for wastewater provides an advanced biological waste treatment program to reduce odor and surface foam. If desired, the process controls targeted deposition and will provide the lowest overall cost of aeration operations in the industry.

High-speed surface aerators lack deep penetration since the process relies on surface splashing and provides a minimal zone of influence. This leads to the industry-wide problem of “flower pots”. This happens when localized vertical aeration allows for dead zones between units where poor mixing contributes to uncontrolled accumulation of deposition.

The Raptor Directional Aeration and Mixing System produces controllable, directional flow of oxygen saturated water. The oxygen is slowly depleted (indicated by color changes from red to white) by aerobic bacteria. The flow reaches the second Raptor and the process repeats itself, creating linkage.

Our Raptor™ Subsurface Aerating Mixer is a technically-advanced horizontal aspirator that delivers:

  • Improved BOD efficiency
  • Improved mixing
  • Targeted deposition removal/control if desired
  • Reduced foam development
  • Odor reduction

The Raptor Directional Aeration and Mixing System’s use of our patented AirWing, combined with the industry best impeller design, provides unmatched directional thrust/linkage control of fine bubble diffusion for energy savings and improved environmental compliance efficiencies. Let us show you how we can provide our process expertise to help you achieve the results you desire for your wastewater treatment operation.

Stock Chest Mixing for Top or Bottom Entering Chests

When compared to competitive product and processes, our application of the Counter Flow impeller paired with a Raven 3800 Series mixer drive results in:

  • Full chest mixing to eliminate dead zones
  • Improved residence time
  • Total uniformity of stock consistency (improved fiber lay)
  • Maximize degassing, 50-60% reduction of entrainment air caused by Pitch Blade Turbines (PBTs)
  • Reduce fiber damage from higher RPM mixing
  • 33-50% reduction in mixing horsepower

Avoid the problems that often arise when using competitive product and process application techniques. Conventional turbines induce entrainment air, require significantly greater power and produce less flow.
