A microbubble generation device comprises a liquid inlet (101), a gas inlet (104), a bubble flow outlet (103), and a gas-liquid mixing chamber (102). An air-permeable hole having an angle structure is provided at a gas-liquid interface of the gas-liquid mixing chamber (102), and a pointed end of the angle structure of the air-permeable hole points to a liquid flow direction. The bubbles generated by the device are extremely small in diameter, prolonging a duration the bubbles stay in the liquid phase, and enhancing gas-liquid mass transfer efficiency.

A device for generating bubbles, comprising a porous material having at least one hydrophilic surface (1), arranged such that a liquid (7) in which the bubbles (6) are intended to be formed may contact the hydrophilic surface (1) and at least one hydrophobic surface (2), arranged such that a gas (5) used to generate the bubbles (6) may flow past the hydrophobic surface (2) before it flows past the hydrophilic surface (1). The device may be used for creating fine bubbles in numerous applications, such as wastewater treatment, plant cultivation, aquafarming, aeration systems, bioreactors, fermeters, oil extraction or fuel cells.

A diffuser is disclosed and includes a channel with an inner portion having an inlet and an outlet through which a gaseous substance enters and exits the diffuser, respectively. The inner portion includes a first conical section that has an increasing cross-sectional area, taken along a plane perpendicular to a central axis, in a first direction. The inner portion also includes a second conical section that has a decreasing cross-sectional area, taken along a plane perpendicular to the central axis, in the first direction. The second conical section is communicatively coupled with the first conical section. The outer portion includes a first annular section that has an increasing cross-sectional area, taken along a plane perpendicular to the central axis, in a second direction opposite the first direction. The diffuser further includes a plurality of orifices that communicatively couple the second conical section with the first annular section.

A container assembly includes a container at least partially bounding a chamber and having a wall with an opening extending therethrough. A tubular stem bounds a passageway and outwardly projects from the wall of the container so that the passageway communicates with the opening. A sparger includes a tubular member having a first end and an opposing second end and an interior surface bounding a passage extending therebetween. A gas permeable sparging member is secured to the first end of the tubular member so that gas passing through the tubular member from the second end passes out through the sparging sheet. A second flange encircles and radially outwardly projects from the tubular member, the second flange being secured to the stem so that at least a portion of the tubular member is disposed within the passageway of the tubular stem.

The present invention relates to an air diffusion device comprising a tubular main pipe for receiving a supply of air from an air supply device, and a branch pipe connected to the main pipe, wherein the branch pipe is connected at one end to the main pipe and open at the other end, one or more air diffusion holes are formed in the branch pipe, at least some of the air diffusion holes are formed so as to be at the top in the vertical direction when the main pipe is laid horizontally, and the branch pipe is configured so that the opening at the other end faces downward in the vertical direction. According to the present invention, it is possible to provide an air diffusion device in which water to be treated is caused to flow into an air diffusion pipe, thereby allowing closing of the air diffusion holes to be suppressed and sediment to be easily removed in the branch pipe as well as an air diffusion method and water treatment device in which this air diffusion device is used.

A container system includes a bag having of one or more sheets of flexible polymeric material, the bag having an interior surface at least partially bounding a chamber that is adapted to hold a fluid. A sparger is secured to the interior surface of the bag so that a compartment is formed between the interior surface of the bag and the sparger. At least a portion of the sparger includes a sparging sheet formed from a flexible sheet of a gas permeable material. A tubular port or tube is coupled with the bag so that a passage bounded by the tubular port or tube communicates with the compartment.

The invention relates to a reactor driven in an oscillatory-rotary manner about its fixed, preferably vertical, axis, for preferably biotechnological and pharmaceutical applications. By means of its process-intensifying properties for mixing, suspension, gaseous material transport, heat transfer, irradiation and particle retention, the applicability on the industrial scale is ensured. The reactor which succeeds without a shaft seal permits particularly robust production with respect to sterile technique with avoidance of cleaning and cleaning validation required when the reactor is constructed as a single-use reactor.
摘要:
A diffuser apparatus which has fine pores is capable of achieving a high oxygen transfer efficiency and rarely becoming clogged so that the apparatus can be operated stably over a prolonged period. The diffuser apparatus includes: an aeration plate that is disposed in an aeration tank in order to release pressurized air, fed from a diffusing air feed pipe, as air bubbles from fine pores formed in an aeration plate surface; blow water feeder for feeding blow water into the diffusing air feed pipe; and an inserted pipe for discharging the blow water, fed into the diffusing air feed pipe, from the aeration plate.
