Abstract: An aeration element for gasification or aeration of liquids includes an essentially flattened, rigid support element having a substantially oval cross-section and corrugated outer surfaces, the corrugated outer surfaces including ridges defining grooves therebetween; a threaded opening for receiving a cooperating fitting for connection to an air supply; and a flexible membrane of elastomeric material disposed around the support element, The membrane has a plurality of slits, and wherein compressed gas is introduced between the support element and the membrane, the gas can escape via these slits into the surrounding liquid. A retaining clamp holds the membrane around at least one end of the support element. A check valve assembly prevents backflow of liquid, particles, sludge or debris into the interior of the support element.

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.

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.
