AquaDDM®

Direct Drive Mixer

The AquaDDM® 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.

Featured Story

AquaDDM® Mixers Chosen Over Submersible Directional Mixers for Optimum Anoxic Mixing

The city of Colorado Springs in Colorado currently operates a 65 mgd wastewater treatment facility. To help meet the stringent water quality standards for denitrification, the facility has employed (20) 7.5 hp AquaDDM mixers. In 1994, Colorado Springs opted to install (20) AquaDDM mixers instead of installing submerged directional mixers.
