The aerating disc which directs the water upon one or more screens is preferably about 1.75 mm thick, and has at least 36 water passages (which may be called chambers) through the disc. The water passages or chambers are parallel to the general direction of flow of water through the aerator and have a cross-section no greater than 0.8 mm.sup.2. The upstream entrance to each chamber comprises at least two entrance openings, the aggregate cross-section of which openings is at least equal to the cross-section of the chamber.
