    Abstract: An aeration device for waste water (1) consists essentially of a carrier (2) with a flat, essentially rectangular surface (3) and of an air-permeable membrane (6) which is connected to the carrier (2). Between the membrane (6) and the carrier (2) there is formed an air chamber (7a, 7b). The rectangular, flat construction on the one hand permits a modular design of the aeration device (1) and further permits the manufacture of the aeration device with the coextrusion method.

    Abstract: Effluent to be treated is introduced into the top of a first bioreactor 10 through an inlet pipe 16 and, after passing through second and third bioreactors 11 and 12, passes through a settling device 17, the treated effluent then flowing over a depth control weir 18 into an outlet pipe 19. The three bioreactors 10, 11 and 12 and the settling device 17 are housed in a tank having three sets of vertically-staggered transverse partitions 21, 22, 23 and a transverse settling tank partition 24. Each set of staggered partitions 21, 22 and 23 are arranged so that the bioreactors are interconnected in series, the effluent preferably being constrained to pass downwardly through each matrix 13, 14, 15 in turn against an upward discharge of very fine air bubbles from aeration panels 28 which extend under substantially the whole of each matrix. Aerobic bacteria feeds on nutrients in the effluent and grows on the roughened walls of the cross-flow matrix and the air bubbles promote sloughing of the bacteria. The apparatus therefore comprises three or more separate total mixed bioreactors working in sequence, each serving to reduce the biological oxygen demand of all the effluent whereby the biological oxygen demand is progressively reduced.

    Abstract: An apparatus for injecting compressed air into a liquid comprises a tubular basic body such as a pipe that is surrounded by a perforated membrane through which air is distributed into wastewater and is connected to the nipple of a compressed air supply through a hollow and cylindrical member that transfers compressed air to the space between the membrane and the tubular basic body and also has a passageway for wastewater so that wastewater can flow through the tubular basic body, thereby avoiding stagnant areas of untreated wastewater.

    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: Aspects of the invention describe a tube diffuser design and associated saddle design that allow the two elements to be easily and quickly attached to each other in the field for the purpose of aerating wastewater. The tube diffuser is cylindrical and includes a gas distribution section spanning across an interior diameter of the tube diffuser. The saddle includes a pair of engagement arms that are able to couple to this gas distribution section of the tube diffuser. Once the tube diffuser is attached to the saddle and the assembly is submerged in wastewater, the saddle may be used to transport air from an air distribution pipe to the tube diffuser. The air may then be made to leave the tube diffuser as a plume of air bubbles.
