AquaDDM®
Direct Drive Mixer
The AquaDDM mixer is designed to provide maximum mixing efficiency. When mixing requirements are the controlling factor, the mixer can reduce power costs, while delivering 3-4 times the mixing of any aerator of the same size.
How It Works
The AquaDDM establishes a powerful down-flow mixing pattern that transports surface liquid downward and increases mass transfer. Flow entrainment and regenerative flow create high reactor turnover rates for efficient mixing.
Ideal Solution for Anoxic Mixing
The AquaDDM® is the ideal mixer for use in anoxic basins for denitrification and phosphorus reduction and provides unrivaled mixing and uniform top-to-bottom blending of the basin. Unlike horizontal mixers, side-entering mixers and submersible mixers, the AquaDDM® provides efficient intermixing of the basin contents – and does not employ any gear reducers, submerged bearings or submerged seals. The AquaDDM® will greatly reduce or eliminate short circuiting, and eliminate dead spots in the basin.
Features & Specifications
- Available in FSS and SS models ranging from 1-75 HP
- Suitable for most basin configurations
- Floating mixer operates in varying liquid depths
- Anti-fouling impeller
- High volume, downflow mixing pattern and near surface intake eliminates short circuiting
- Eliminates or greatly reduces surface splashing and foaming
- Submerged intake volute eliminates air entrainment
Benefits
- Lower initial cost, and less expensive to install and maintain than gear reduced (slow speed) units
- More reliable service than submerged directional mixers
- High efficiency mixing reduces power consumption
- One-piece stainless steel shaft; no couplings or submerged bearings
- High efficiency and Endura® Series motor options are available

SAF-T Float® Technology
The SAF-T Float® Safe Accessible Float Technology is the result of customer feedback for a solution that provides service personnel with safer, easier and more accessible maintenance on Aqua-Jet® aerators and AquaDDM® mixers. This new technology encompasses two critical features: 1) a docking station each float that receives a set of lightweight, removal handrails and; 2) a non-skid coated surface onto the section of the float where the handrails attach, providing a safe grip for maintenance staff to stand on the float.
