SSI Aeration Retrievable Systems

If you need to install an aeration system without dewatering the basin, you have a single aeration basin, or aggressive wastewater that requires more frequent observation of diffusers, then a retrievable aeration system could be the answer.

SSI has significant experience manufacturing retrievable aeration systems for both wet and dry installation, utilizing flexible hose or rigid stainless steel drop pipes. Systems can be made crane or winch liftable, and can be manufactured with either tube or disc diffusers, and can be made without guide rails, or with single or dual guide rails. Air may be fed either from the side of the basins, or from floating pipes on the surface.

The wire to water efficiency of a retrievable fine bubble grid, when properly designed, is similar to that of a fixed grid system. Since this efficiency can be as much as two times the efficiency of mechanical aeration, retrievable systems are often considered for supplemental aeration in oxidation ditches and lagoons, where the existing mechanical aerators cannot supply enough oxygen.
