Abstract: A flexible diffuser membrane for diffusing gas into a liquid includes a substrate covered wholly or partially by a thin fluorocarbon elastomer coating. The coating is applied after the substrate has been fully constructed and cured. The coating is then mixed with an adhesive catalyst and applied by spraying or in another suitable manner to the substrate. The substrate and coating are then heated to a temperature such as 350° F.-800° F. adequate to form a strong chemical, molecular and adhesive bond between the coating and substrate. Perforations are formed in the membrane, the substrate may be treated with a biocide allowing the uncoated edges of the perforations to be coated with the biocide and resist biological growth.

Abstract: Membrane strip diffusers are disclosed, useful for example in aerating wastewater in activated sludge plants. These diffusers have membranes, diffuser bodies and gas conduits elongated in the same general direction. Such conduits may be attached to or formed integrally with the diffuser bodies. Gas chambers form beneath the membranes when they inflate, and these are separate from but communicate with the gas conduits, e.g., through passageways distributed along the lengths of the membrane supports. Preferably, the passageway flow cross-sections are small, thus tending toward uniform distribution of gas along the membrane's length. Ways to edge- and end-seal the membranes to the diffuser bodies are also disclosed.

Abstract: An aeration system for a submerged membrane module has a set of aerators connected to an air blower, valves and a controller adapted to alternately provide a higher rate or air flow and a lower rate of air flow in repeated cycles. In an embodiment, the air blower, valves and controller, simultaneously provide the alternating air flow to two or more sets of aerators such that the total air flow is constant, allowing the blower to be operated at a constant speed. In another embodiment, the repeated cycles are of short duration. Transient flow conditions result in the tank water which helps avoid dead spaces and assists in agitating the membranes.

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.
