AquaDDM Direct-Drive Mixers

The Aqua-DDM® Mixer provides maximum wastewater mixing efficiency. When mixing requirements are the controlling factor, the AquaDDM mixer can reduce power costs, while delivering 3-4 times the mixing of any aerator of the same size. The ducted impeller improves pumping efficiency. The integrated flow vanes and lower input torque eliminate the need for tank baffles.


  • Flexibility in materials of construction
  • Heavy duty bearings and seals
  • Anti-fouling impeller


  • Simple physical construction makes handling easy
  • Lower initial cost, and less expensive to install and maintan than gear reduced (slow speed) units
  • Better and more reliable service than submerged directional mixers
  • One-piece stainless steel shaft. No couplings, no submerged bearings

Typical Application:

  • Anoxic Systems
  • Back Mixing
  • Equalization
  • Disinfection
  • Neutralization
  • Denitrification
  • Directional Mixing
  • Blending Combined Streams
  • Sequencing Batch Reactors (SBRs)
