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 (Open discharge weir)

ATB Water’s CWE Clear Water Extractor with open discharge weir is designed to discharge the clear water layer below the surface and block bulking sludge and floatables. The float is positioned by a guiding system with optional wall brackets. The attached limiting legs prevent damage to the discharge system when emptying the tank. To prevent the tank fully emptying the length of the legs can be adjusted so that the CWE weir stops at the lower trigger point.
