Appts. for diffusion of gas into a liq. - partic. of oxygen for regeneration of polluted waters

Abstract

Abstract Appts serves for the introduction of air or oxygen into the water in the form of fine bubbles. An assembly of diffuser units is installed on the bottom of a lake or large mass of water. The units are provided with parallel slits through which a dispersion of bubbles of oxygen in water is evacuated; the bubbles slowly rise to the surface. Oxygen from a common source, is supplied to the distribution pipe while water, drawn from the lake, is forced by a pump into the diffuser with its slits. The bubbles of gas are entrained by the water; a cloud of bubbles is formed which extends to a considerable distance from the diffuser. The appts promotes the absorption of the gas into the mass of water and reduces the loss of gas by bubbling into the atmos. The diffuser can be used for the treatment of sewage, for fermentation and other processes in which a gas has to be diffused into a large mass of liq.
