Mechanical aerators are an excellent low capital costs aeration option with the advantage of maintaining the same performance efficiency for the life of the equipment. Ideal for smaller tank applications to larger scale earthen basins, mechanical aeration can be utilised in shallow or deeper water levels.

Where other aeration technologies require large infrastructure frameworks, mechanical aerators are simple to install, use, move and maintain.

Clear Water Extractor (Closable discharge weir)

The ATB Water CWE-EMC Clear Water Extractor is equipped with a linear actuator which closes the weir watertight to the bottom of the float. This automatic closure system ensures no sludge can get into the overflow during aeration and mixing. Its floating construction means it is always in the best position in the clear water layer below the water surface.
