Aerator-mixer Landox

The Landox Channel Aeration System combines vertical drum mixers with fine bubble diffusion in an oxidation ditch arrangement. The design of the Landox Channel Aeration System separates mixing and aeration into independent operations. This separation allows for power turn-down of aeration given variable influent conditions while maintaining constant mixing. Independent control of the aeration also provides the ability to accomplish simultaneous nitrification and denitrification in the same reactor. Fine bubble diffusers have commonly been used in oxidation ditch applications. Typically the mixing will be done with submerged flow boosters installed in the ditch channels. The Landox mixing drum would replace these submerged flow boosters with a mixer that has all maintenance items above the water level. The Landox mixing drum rotates slowly to avoid any rags or fibrous material from collecting on the equipment. Plant operators have strongly endorsed this system to eliminate the maintenance of a submerged flow booster.
