The impeller and one-piece shaft are dynamically balanced to provide smooth operation and maximum bearing life. Options Directional Flow Assembly The AquaDDM® is available with an optional directional discharge assembly which converts the downward vertical flow to a horizontal flow. The AquaDDM® with a directional flow assembly is ideally suited for use in long narrow tanks and oxidation ditches where directional flow may be necessary or desirable. In such applications, the AquaDDM® with a directional flow assembly greatly reduces or eliminates short circuiting of the basin, eliminates deadspots and provides exceptional mixing of the basin contents. Contact Your Local Representative: Anti-Erosion Plate Aqua-Aerobic Systems has designed an anti-erosion plate for use in those applications which the AquaDDM® is installed in earthen basins. Our unique patented installation procedure allows the anti-erosion plate to be easily installed without dewatering the basin. With the use of a float mounted winch, the anti-erosion plate is suspended from the float of the AquaDDM® directly below the discharge volute. The mixer and plate are then towed into position and lowered, as one, into the basin. Patent #s 4,422,771 – 4,733,972 – 4,723,848 – 4,764,053 apply. Canadian patent #1,182,445.

AquaDDM® Mixer FSS Series Proven mixing efficiency AquaDDM® The 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.

Anoxic Basins The AquaDDM® is the ideal mixer for use in anoxic basins for electrification and phosphorus reduction. 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 deadspots in Aqua MixAir Improved aeration efficiency Aqua-Aerobic Systems offers the Aqua MixAir® system which...
