    Abstract: A device for aerating water, and including a rigid, essentially planar support member, and thereupon a plate of elastomeric material that is provided with fine slits for the release of air. The underside of the support member is provided with one or more connectors for supplying air between the support member and the plate. The rim of the plate is pressed in an airtight manner from above against the support member by a profiled annular frame that is secured by screws to the support member. The frame has a flat portion via which it rests against the plate, and also has an annular reinforcing rib that is directed upwardly away from the plate, so that the frame has an L-shaped or T-shaped cross-sectional shape. The frame also has an outer peripheral portion for receiving fastening screws.

    Abstract: Apparatus for agitating and aerating sewage and industrial waste comprising a plurality of flexible, inflatable cells disposed in the bottom of a liquid waste holder and means for supplying and withdrawing air to and from the cells so as to cause them to periodically inflate and deflate, whereby the liquid is agitated by the varying water displacement of the cells. Aeration is accomplished by providing the cells with gas-escape orifices that permit air to escape from the cells into the surrounding liquid at controlled rates in the form of small bubbles that rise in the liquid and make intimate contact with suspended solids.

    Abstract translation: 用于搅拌和充气污水和工业废物的装置，包括设置在液体废物保持器底部的多个柔性的可充气细胞和用于向细胞提供空气和从细胞排出空气的装置，以使它们周期性地充气和放气，由此 液体被细胞的水位变化所搅动。 充气通过为细胞提供气体逸出孔，其允许空气以受控的速率从细胞逸出到周围的液体中，其形式为在液体中升高并与悬浮固体紧密接触的小气泡。
