An aerator includes an air supply chamber into which air is supplied by an air supply pump, a water flow channel connected to a water feed pipe, and a gas-permeable porous body having multiple gas discharge pores and separating the air supply chamber and the water flow channel. Air in the air supply chamber is pushed into water in the water flow channel through the gas discharge pores of the porous body due to discharge pressure of the air supply pump. In the porous body, inner surfaces of the gas discharge pores are coated with a coating film made of a water repellent having such a wettability that a water droplet contact angle is 80 degrees or more and preferably 90 degrees or more, on a smooth flat film surface.

The disclosure provides a gas-liquid dissolving apparatus, comprising: a sealed tank, a gas jet tube and a plurality of membrane plates; the sealed tank being provided with a liquid supply joint at top, and a gas inlet joint and an output joint at bottom; the gas jet tube being located inside the sealed tank and connected to the gas inlet joint; the gas jet tube having a plurality of gas jet holes distributed on tube wall; the plurality of membrane plates being stacked around the periphery of the gas jet tube and fixed; each membrane plate being ring-shaped, and being structured with an inner ring wall, a mixing chamber and an outer ring wall sequentially from the center; the mixing chamber having an opening facing downward, and the inner ring wall being thicker than the outer ring wall, with a gap existing between the two adjacent stacked outer ring walls.

A method for processing a fluid includes removably securing a retention member to a vessel that bounds a chamber; inserting a collapsible bag within the chamber of the vessel; securing the bag to the retention member so that the bag is supported within the chamber of the vessel; and dispensing a fluid into a compartment of the collapsible bag supported within the chamber of the vessel. The fluid can be mixed within bag while the bag is disposed within the vessel.

A reciprocating stirrer device with which favorable gas absorption into the stirred substance can be obtained. The reciprocating stirrer device is obtained from: a stirring vessel in which the substance to be stirred is placed; a reciprocating drive shaft provided inside the stirring vessel; a stirring blade connected and affixed so as to intersect the drive shaft; and a microbubble-generating unit. The microbubble-generating unit is obtained from a sparger that is made of a porous body and a gas supply means for supplying a gas to the sparger. Bubbles are generated in the substance being stirred by passing gas supplied to the sparger by the gas supply means through pores of the porous body.

A water container with an ozone diffuser is an apparatus that is used to diffuse ozone gas into water that is either flowing through the apparatus or is retained by the apparatus. The apparatus includes an aeration chamber, an ozone generator coupler, a distribution hub, a plurality of porous tubes, and a degassing unit. The ozone generator coupler allows the apparatus to connect with a pressurized supply of ozone gas. The aeration chamber is used to retain the water that is currently being aerated by the ozone gas. The distribution hub receives the ozone gas from the ozone generator coupler and distributes the ozone gas amongst the porous tubes. The ozone gas is then evenly inserted from the porous tubes into the water retained by the aeration chamber. The degassing unit is used to neutralize the excess ozone before exhausting the excess ozone into the apparatus's surroundings.

An NO-accumulation apparatus, method and use, comprising: a container (120) defining a cavity for accommodating a liquid (105), an inlet (150) for feeding the liquid into the container (120) and an outlet (151) for delivering the liquid from the container (120) to a bath unit; an NO-gas dissolving unit (140) for dissolving gaseous NO in the liquid (105) to produce an NO-containing liquid, wherein the NO-gas dissolving unit (140) is arranged in the container (120) and/or forms a part of the container (120); and an NO-gas port (110) in fluid communication with the NO-gas dissolving unit (140), wherein the NO-gas port (110) is adapted for coupling, particularly for releasably coupling, with an NO-gas supply, whereby the apparatus further comprises means for decoupling the inflow of NO to the liquid (105) within the container from the removal of the NO-containing liquid (NO-decoupling means), so that the removal of the NO-containing liquid is inhibited, when the NO is flowing into the liquid, and also the NO inflow is inhibited when the NO-containing liquid is removed from the container (105).

An apparatus for producing nano-bubbles in a volume of liquid is described. The apparatus includes a motor having a rotatable shaft, an axially rotatable permeable member couplable to a gas inlet, and a rotatable tube support coupled to the rotatable shaft of the motor and having an inner cavity that houses the axially rotatable permeable member. When rotated, the axially rotatable permeable member is rotated so that the surface velocity of the rotatable permeable member simulates axial turbulent flow above the turbulent threshold in the liquid that allows the liquid to shear gas from the outer surface of the axially rotatable permeable member, thereby forming nano-bubbles in the liquid.

An apparatus, system, and method for contacting blood with ozone to kill microorganisms in the blood are described. The method involves injecting microbubbles of ozone containing gas into a flow of blood, preferably at a temperature of less than 12 C. The apparatus includes a blood flow conduit including a blood ozone contacting portion including a porous ozone injector.

Embodiments of the present disclosure describe an aquaculture environment control system comprising one or more control apparatuses positioned within a vessel at an angle relative to a proximal vessel wall and configured for scouring of the vessel, wherein each control apparatus has a discharge conduit and each discharge conduit has one or more orifices; and a fluid source in fluid communication with each of the control apparatuses. Embodiments of the present disclosure describe a method of controlling an aquaculture environment comprising supplying one or more of a fluid and gas to a control apparatus positioned within a vessel at an angle relative to a proximal vessel wall; and discharging one or more of the fluid and gas from the control apparatus at a fluid velocity sufficient for scouring of the vessel.

An expansion chamber includes a chamber body having a top portion above a bottom portion cooperatively forming a hollow chamber volume configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, including wine and other alcoholic beverages. The bottom portion has a bottom opening configured to engage an opening of an uncorked and/or opened wine bottle. The top portion has a top opening. The hollow chamber volume is configured to be in fluid communication with an inside of the uncorked and/or opened bottle when the bottom opening is engaged with the opening of the uncorked and/or opened bottle. A maximum inside diameter of the hollow chamber volume in a horizontal plane with respect to the uncorked and/or opened wine bottle set upon a horizontal surface is cooperatively formed between the top and bottom portions, wherein the maximum inside diameter is at least 2.50 inches.
