The AquaDDM® Mixer is designed to provide maximum mixing efficiency. For those applications where mixing requirements are the controlling factor, the AquaDDM® can reduce power costs, while delivering 3-4 times the mixing of any aerator of the same size. The ducted impeller of the AquaDDM® improves pumping efficiency; and the integrated flow vanes and lower input torque eliminate the need for tank baffles.
The AquaDDM® establishes a powerful downflow mixing pattern that transports surface liquid downward and increases mass transfer. Flow entrainment and regenerative flow create high reactor turnover rates for efficient mixing.
Features and Benefits
- Low initial cost, and less expensive to install and maintain
- Motor options: explosion proof, high efficiency and Endura® Series
- No couplings, gear boxes or submerged bearings
Suitable for most basin configurations
Downflow discharge eliminates short-circuiting
Standard mooring arrangements
Directional flow option
Horsepower: 3 to 75
For those aeration applications where the mixing energy requirement is greater than the aeration requirement, the AquaDDM® mixer will provide mixing more efficiently than a combined aeration/mixing device. This may result in considerable energy savings while providing greater flexibility of operation.
Examples where an AquaDDM mixer can play a key role include: activated sludge systems, anoxic systems, back-mixing, biomass conditioning, biomass suspension, denitrification basins, directional mixing,equalization, MixAir® systems, neutralization, SBR systems and storm flow basins.
