Infinitely variable draft is a unique feature of aquaturbo® Model AER-AS. Each Floating Surface Aerator has a standard draft with an associated minimum and maximum water level range. The draft can be reduced or extended within the operational limits of each model.
Optimum mixing and oxygen transfer is achieved when the correct draft is selected to suit the water level. Final aerator selection and exact draft is dependent upon many factors including basin construction (concrete, earthen, membrane liner or other), water level fluctuation; nature and degree of settled deposits, process objectives (complete mix, partial mix, laminar mix or other) and whether the influent is screened.
An Anti-erosion Plate is often specified for operation in shallow earthen or membrane lined basins and when settled deposits are present.
