  • Patent number: 10029924
    Abstract: Method and apparatus for treating potable water in municipal and similar tanks to reduce and remove undesirable disinfectant byproducts such as trihalomethanes from the water by providing a water circulation system to create circulation patterns in the tank water and an air flow system for creating an air flow pattern in the headspace region of the enclosed tank above the water surface. In operation, a portion of the tank water is drawn-up a draft tube from the tank floor to above the water surface and sprayed through a nozzle outwardly about a vertical axis and slightly downwardly toward the surface of remaining tank water. The air flow system creates and directs a high volume of air through the tank above the water surface to volatize undesirable trihalomethanes in the drawn-up water portion to gaseous state to enter the air flow pattern and exit the tank into ambient air.

  • Patent number: 9656218
    Abstract: A method and apparatus for injecting a gas into a liquid in which a rotating helical impeller within a draft tube submerged in the liquid creates a liquid flow within the draft tube. Gas bubbles are injected into the draft tube either above or below or alongside the helical impeller or in all three locations. The liquid is drawn into the draft tube with a superficial velocity greater than a substantially uniform terminal ascent velocity of the gas bubbles to allow entrainment of undissolved gas bubbles in the bulk liquid into the liquid being drawn into the draft tube. The gas bubbles are injected with a uniform diameter of between about 10.0 microns and about 1.0 millimeters. The small bubble size enhances the dissolution of the gas into the liquid and also allow the entrainment of the gas into the liquid being drawn into the draft tube.

  • Patent number: 8876089
    Abstract: An aeration system has aerators that remain generally full of air when the supply of pressurized air is turned off or vented. Water does not reach the bubble discharging holes of the aerator, which are kept from plugging. The aerator has a body with a hole through a wall of the body to discharge bubbles. The hole is surrounded by a skirt at the wall of the body. The skirt extends to below the elevation of the hole. The aerator body is connected to a source of pressurized gas through an open bottomed chamber. An opening between the aerator body and the inside of the chamber is located below the elevation of the hole. When the supply of gas is off, water enters the chamber and possibly the skirt. However, the water can only rise until it has reached the skirt and the opening, both of which are below the hole, and the entire aerator body is kept dry. Aerator fouling is reduced, and the aerator begins to produce an even flow of bubbles quickly when the supply of gas returns.

    Abstract: A desalination system in the form of a submerged gas evaporator that includes a vessel, a gas delivery tube partially disposed within the vessel to deliver a gas into the vessel and a fluid inlet that provides a fluid to the vessel at a rate sufficient to maintain a controlled constant level of fluid within the vessel. During operation, gas introduced through the tube mixes with the fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence, thereby promoting vigorous mixing and intimate contact between the gas and the fluid, which leads to a more efficient and complete evaporation. Additionally, vapor exiting the submerged gas evaporator is condensed in a condensing unit thus precipitating vapor into a liquid for removal.

  • Patent number: 8136797
    Abstract: A cooling tower includes an evaporator vessel, a gas delivery tube partially disposed within the evaporator vessel to deliver a gas into the evaporator vessel and a water inlet that provides water to the evaporator vessel at a rate sufficient to maintain a controlled constant level of water within the evaporator vessel. A weir is disposed within the evaporator vessel adjacent the gas delivery tube to form a first fluid circulation path between a first weir end and a wall of the evaporator vessel and a second fluid circulation path between a second weir end and an upper end of the evaporator vessel. During operation, gas introduced through the tube mixes with the water and the combined gas and fluid flow at a high rate with a high degree of turbulence along the first and second circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the water.

  • Patent number: 8079572
    Abstract: A device for gassing a liquid, particularly for membrane facilities used in immersion operation, has a gas supply channel and at least one gas lance from which a gas flow exits in gassing operation. The gas lance is connected to the gas supply channel via at least one connection channel including a first mouth area on the side of the gas lance and a second mouth area on the side of the gas supply channel and generating as a throttle a flow pressure loss of the gas flow entering the gas lance. Below the first mouth area an extension section is provided, which adjoins the gas lance and has an opening below the first mouth area.

  • Patent number: 8056887
    Abstract: A surface aerator for mixing gas and liquid is disclosed. The surface aerator has an upwardly pumping impeller located within a draft tube. A flow diverter redirects pumped liquid from the impeller traveling in an upward direction to a radially outward direction where it impacts and aerates the remaining liquid in a vessel. A baffle extends radially at a shallow depth to a point beyond the impact area of the liquid to provide separation of the impact area from the rest of the liquid and promote aeration.

  • Patent number: 8043479
    Abstract: A desalination system in the form of a submerged gas evaporator that includes a vessel, a gas delivery tube partially disposed within the vessel to deliver a gas into the vessel and a fluid inlet that provides a fluid to the vessel at a rate sufficient to maintain a controlled constant level of fluid within the vessel. A weir is disposed within the vessel adjacent the gas delivery tube to form a first fluid circulation path between a first weir end and a wall of the vessel and a second fluid circulation path between a second weir end and an upper end of the vessel. During operation, gas introduced through the tube mixes with the fluid and the combined gas and fluid flow at a high rate with a high degree of turbulence along the first and second circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the fluid.

  • Patent number: 7963508
    Abstract: A method and apparatus for aerating liquid which includes an aeration chamber having an inlet port at its lower end an outlet port at its upper end wherein the chamber is divided into multiple internal chambers using a plurality of internal divider walls. The chamber is weighted with a base member so that it will not float. Air is inlet at its upper end through an air inlet hole into an upper air manifold wherein the air then travels downwardly through an air feed pipe to a plurality of air outlet holes wherein the air is released and rises thereby causing a flow of material through the inlet ports upwardly along the internal divider walls and aeration chamber and then out of the chamber at its upper outlet port so that the stream of material is directed onto a series of stationary concentric ridges wherein the solids in the liquid material are forcefully impacted against the stationary concentric ridges so as to break the solid particles up into smaller particles.

  • Patent number: 7926791
    Abstract: An oxygen therapy humidification device is disclosed. The humidification device includes a hollow water reservoir that includes an upper end that has an upper cross-sectional area and a lower end that has a lower cross-sectional area. The lower cross-sectional area is smaller than the upper cross-sectional area. The device also includes an oxygen inlet and an oxygen outlet, both of which are positioned at the upper end of the hollow water reservoir and provide fluid communication to and from the hollow water reservoir. The oxygen inlet includes a bypass valve that is connected to a duct that extends from the oxygen inlet to a diffuser that is positioned at the lower end of the hollow water reservoir. The bypass valve allows the user to control the proportion of water vapor or humidity delivered to oxygen that is passed through the device, with the oxygen entering through the inlet and leaving through the outlet at the desired humidity level.
