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.
