Abstract: A first slit 12A formed in a diffuser membrane of aeration diffusers of an aeration apparatus according to the present invention includes a linear reference slit 12a and a branched slit 12b crossing the linear reference slit 12a at a center thereof, and an opening shape of the first slit 12A is deformed due to pressure of air (an amount of air) to be supplied. Therefore, because an opening amount at a crossing 12c of the linear reference slit 12a and the branched slits 12b increases by temporarily increasing the amount of air, elimination of precipitates is facilitated, differently from conventional cases having only linear slits.

Abstract: A wastewater treatment includes an elevated aeration system. The aeration system is used to provide air and nutrients to biological growth in a wastewater treatment vessel, and to promote circulation of the support media used for the biological growth. The aeration system is elevated from the bottom of the reactor vessel by supports that extend from sidewalls of the vessel, or from suspension systems that hang the aeration system at a desired height. Silt, debris and sludge may be removed from the free space between the elevated aeration system and the vessel floor. Mechanical collection or removal devices may be positioned between the elevated aeration system and the reactor floor.

Abstract: A micro-bubble generating device is provided which is capable of mixing or dispersing micro-bubbles into a liquid with high stability and has a simple structure that permits reduction of a cost of manufacture. A first member and a first packing are superposed on each other on one side of a gas-permeable film, while a second member and a second packing are superposed on each other on the other side of the gas-permeable film. A pressurized gas delivered via a gas inlet of the first member flows through a fluid passage of the first packing, permeates through the gas-permeable film, and is ejected as micro-bubbles into a liquid flowing through a fluid passage in the form of a narrow shallow strip-like groove provided in the second packing.

Abstract: A flexible diffuser membrane for diffusing gas into a liquid includes a substrate covered wholly or partially by a thin coating. The substrate is formed by a mold or extruder and is of an elevated temperature upon exiting the mold or extruder. The coating may be applied directly to a selected surface of the substrate just after it exits the mold or extruder and while the substrate is at an elevated temperature and before it may become contaminated by foreign materials. The membrane's manufacturing process may be a substantially continuous process wherein the substrate is continuously formed by an extruder and the coating is applied to the substrate in a continuous manner as the substrate exits the extruder.

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: 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.
