Abstract: An apparatus for aerobic biological treatment of waste water and the like includes a tank configured to retain waste water therein, and a wheel rotatably mounted in the tank. The wheel includes a plurality of chambers arranged in axial succession about the circumference of the wheel. The chambers include openings which are oriented generally upwardly and emerge from the waste water adjacent a top dead center position of the wheel and are oriented generally downwardly and submerged in the waste water adjacent a bottom dead center position of the wheel. An air drive mechanism rotates the wheel, and an air pipe communicates with the air drive mechanism, and is disposed generally below the wheel, and is configured to release air bubbles therefrom after the bottom dead center position. A plurality of bubble connectors are connected with and protrude radially outwardly from the wheel at locations preceding the openings, and are shaped to guide the bubbles from the air pipe through the openings into the chambers.

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: A gasification device is described for the introduction of a gas into a liquid, in particular of air into waste water. The gasification device has a blower body element, which carries a membrane made of an elastic material with perforation slits. The gasification device also has a longitudinal ridge arranged in an area located at the top, related to the installation location. When the gas feed is switched off and the hydrostatic pressure of the waste water is imposed, an axial fold of the membrane is formed in this upper area. This area is, at the same time, free of perforation slits.

Abstract: A process for treating BOD, nitrogen and phosphorus containing wastewater. The process includes introducing wastewater influent into an anaerobic zone having activated sludge and mixing the wastewater influent with the activated sludge in the anaerobic zone to form a mixed liquor. The mixed liquor is introduced into an oxygen-deficit aeration zone, and denitrified mixed liquor from the oxygen-deficit aeration zone is recycled to the anaerobic zone for mixing therein with wastewater. The process also includes transferring the mixed liquor from the oxygen-deficit aeration zone to an oxygen-surplus aeration zone, transferring a portion of the mixed liquor from the oxygen-surplus aeration zone to a settling zone wherein a supernatant is separated from settled sludge and recycling at least a portion of the settled sludge to the oxygen-deficit aeration zone as recycled activated sludge.

Abstract: A fine bubble diffuser membrane used in the aeration of wastewater is treated with biocide to inhibit growth and accumulation of biological materials on the membrane. The membrane may be constructed of EPDM rubber or urethane. The biocide may be carbolic acid either dispersed throughout the membrane or applied as a coating on the surface of the membrane exposed to the wastewater. The membrane is a flexible and elastic structure impervious to liquid and provided with slits that close to prevent wastewater inflow in the absence of aeration and open in response to aeration pressure to discharge air into the wastewater.
