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: Tube units useful for a variety of application are provided. Preferably, individual laminated tubes are joined to each other by intermediate pieces to produce a wide ribbon of parallel tubes. The tubes are porous to certain substances, allowing them to serve as an apparatus to exchange material between two or more fluid streams. The tubes are particularly useful as membrane modules for exchange of material between two fluids. Continuous and discontinuous methods for constructing such tube units are also taught.

Abstract: An apparatus for aerobic biological treatment of waste water is described, in which a great number of carrier members having a large surface area to which microorganisms adhere are movably set in a cylindrical reactor within a given range of height, and the carrier is horizontally moved substantially continuously so that a part of the carrier is cleaned with cleaning air. The partial cleaning system eliminates the disadvantages associated with intermittent cleaning of the whole carrier.

Abstract: A large area sparger has a gas-permeable diffuser bonded to a gas-impermeable underlying element so that inflowing gas is distributed throughout a gap between the sparger and the underlying element. Bonding regions interconnect the diffuser and the underlying element around the sparger perimeter and throughout a gap region within the perimeter in a pattern that keeps the diffuser flat during operation and allows gas to flow around the bonding regions to reach all of the unbonded area of the diffuser. By giving the diffuser a liquid interface surface with a high surface energy, the gas passing through a finely porous diffuser departs from the diffuser interface surface and enters the liquid as very fine bubbles having a large area of contact with the liquid.

Abstract: Wastewater and recycled activated sludge are homogeneously mixed in a first aeration zone by injecting an oxygen-containing gas such as air into the lower portion of the zone under conditions which produce a complete mix reaction and sufficient oxygen is supplied to meet the biological oxygen demands of the mixed liquor. The gas is introduced, preferably by a plurality of fine bubble membrane diffusers, in the form of fine bubbles having a diameter less than about 4 mm. The bubbles provide both the mixing to keep solids in suspension and the oxygen required to maintain the overall dissolved oxygen content in the first aeration zone as close to 0 as possible. The mixed liquor is sequentially contacted with an oxygen-containing gas in second and third aeration zones under conditions which produce a complete mix reaction, preferably by fine bubble membrane diffusers, clarified and a portion of the settled sludge is recycled to the first aeration zone.
