ABSTRACT:
Provided in an apparatus for sewage treatment is an improvement including, a recycling means for recycling gas from the upper portion of a vessel through a pumping means to pressurize the gas and into a second dispersing means, a second dispersing means comprising means for enabling a stream of pressurized gas from a plurality of gas dispersing nozzle assemblies to impinge upon a major portion of sludge being channeled from a first sludge dispersing means and to divide and disperse sludge particles within the upper portion of the vessel to become oxygenated as they interact with oxygen in the upper portion of the vessel, and to enable the oxygenated particles to fall to an to be collected in the lower portion of the vessel, each nozzle assembly directing a stream of the pressurized gas toward one outlet of a channeling means of the first dispersing means, the outlets of the first sludge dispersing means being arranged radially about the first sludge dispersing means, the nozzle assemblies being arranged radially about the first sludge dispersing means and along an inner wall of the vessel in generally horizontal alignment with the outlets.
