  • 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.

  • Patent number: 8794604
    Abstract: A method for generating and dissolving nano-bubbles in a liquid comprises the steps of preparing a bamboo filter by partially or entirely removing an enamel layer of a bamboo and using a bamboo fibrous layer therein as a component of a filter; applying a gas to an inside of the bamboo filter with a pressure over atmospheric pressure in a state where the bamboo filter is submerged in water; and making the gas permeate from an inside of the bamboo fibrous layer to an outside thereof, thereby forming nano-bubbles and at the same time dissolving the gas in the liquid. The present invention advantageously allows the generation of nano-sized fine bubbles by a filter member made of naturally occurring material so that the nano-bubbles are dissolved in a liquid, without applying external mechanical force to the water.

  • Patent number: 8740195
    Abstract: Systems and methods for diffusing gas into a liquid are disclosed. In some cases, the methods include tangentially introducing a liquid into a cylindrical chamber having a cylindrical inner wall such that the liquid develops a spiral flow. In some cases, gas bubbles are orthogonally introduced into the liquid as the liquid flows through the chamber. In some cases, a flow of the liquid and the gas bubbles is controlled such that a ratio of a liquid flow rate to a gas bubble flow rate does not exceed values which convert non-bacteria enriched, clear water into froth. In such cases, a mixture of the liquid and the gas bubbles to exit the chamber near an output end. While the liquid can include clear water, in some instances, the liquid also includes bacteria (e.g., surfactant-producing or non-surfactant-producing bacteria) and/or bacterial nutrients that allow for improved bioremediation.

  • Patent number: 8678358
    Abstract: The buoyant aerator with support legs is disposed in a body of water and supplied with air from a remote source. The remote source may be land-based or based upon a floating vessel. An air supply line extends from the remote air source to the aerator, the supply line being supported by one or more rigid poles or columns anchored into the floor of the body of water. The entire aerator structure floats to hold the aerator at a constant level and is held in position by restraining cables. A plurality of rigid support legs extends from the periphery of the float to support the aerator in conditions where the water level drops below the height of the aerator as defined by the vertical distance between the float and the support pads of the legs.

  • Patent number: 8657268
    Abstract: Wastewater is treated by providing a distribution conduit and providing a diffuser assembly. An aperture is created in the distribution conduit having an initial minimum diameter. The diffuser assembly, in turn, comprises a diffuser membrane in fluidic communication with a mating tube. The mating tube has an initial outside diameter at a location along its length greater than the initial minimum inside diameter of the aperture. The mating tube is inserted into the aperture until the location on the mating tube that, before insertion, had the initial outside diameter is encircled by the aperture where the aperture, before insertion, had the initial minimum inside diameter. This forms an airtight interference fit between the distribution conduit and diffuser assembly.

  • Patent number: 8632058
    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.

  • Patent number: 8622370
    Abstract: The aerator air distribution manifold has a central plenum disposed at the lower end of a concentric rigid downpipe or duct, and a radial array of diffuser tubes extending from the plenum. Since the aerators are buoyant, the aeration tubes are deployed at a constant, uniform depth below the surface of the water at all times, regardless of the water level. All of the aerator manifolds receive their air supply from a remotely disposed air source. The air source may be based on shore, or may be based upon a ship or other floating vessel. A flexible air supply line or hose extends from the air supply to each of the buoyant aerators, the hose being supported by one or more rigid columns or poles anchored into the bottom of the body of water in which the aerators are placed.

  • Patent number: 8544492
    Abstract: The present invention is a modular tower structure comprising a common up-flow column topped with a covered header to which multiple independent down-flow and scavenger columns are attached. It employs a renewable energy process for extracting energy from the atmosphere. The process works by creating a vacuum into which atmospheric air is drawn through a vacuum operated motor driver. The motor in turn can operate other mechanisms as electric power generators. A scavenger column and a header operate independently to collect and remove air before it can accumulate in the tower header and interfere with the siphon process. The tower header is equipped to remove solids or floatables before they can collect at the top of the header and interfere with the process. The header cover is removable for inspection and ease of maintenance.

  • Patent number: 8512561
    Abstract: The water aerator using a compressed gas container is a self-contained unit having a float and a container of compressed gas (e.g., air, oxygen, etc.) installed beneath a perforated diffuser plate that, in turn, is positioned below the float. High-pressure gas from the container flows through a pipe or tube to a regulator valve and pressure gauge at the top of the pipe. A larger diameter low-pressure pipe or tube is placed concentrically about the high-pressure pipe. Regulated low-pressure gas flows down through the outer low-pressure pipe to a dispensing nozzle below the diffuser plate, whereupon the gas flows upward and is broken up by the perforations in the diffuser plate to form smaller aeration bubbles. An electrical power source, pressure switch, and light may be provided to indicate when the compressed gas container is depleted. The device may be motorized.
