The Quick Connect Diffuser Assembly of the present invention includes a special saddle in fluid communication with an air distribution header pipe and a diffuser body connected to the special saddle. The saddle is connected to the air distribution header pipe with a two interlocking sections joined on one side with a hinge, and on the other with flanges. The flanges are connected with a wedge piece. The diffuser connects to the upper saddle section with a bayonet type Quick connection. Gas is forced from the air distribution header pipe through an orifice hole in the pipe, then through the saddle and exits the diffuser body through a diffusion membrane. The membrane forms the gas into fine bubbles that aerate liquid contained in a basin. A single saddle assembly is adaptable to mount on either US or Metric pipe, which have different outside diameters, by changing gaskets and an O-ring.
A diffuser assembly for application to an aeration pipe having an outlet port adapted for immersion in liquid with a longitudinal axis of pipe oriented on a common horizontal plane, said diffuser assembly comprising:

This invention relates to an improvement in a diffuser assembly for use in the aeration of liquids, more particularly sewage waste water and industrial waste water.
Diffused aeration systems supply oxygen to waste water, and keep solids in suspension with gentle mixing. Diffusing ambient air into waste water from municipal sources or from commercial or industrial installations facilitates the growth of particular bacteria. These bacteria then produce beneficial enzymes.
A piping network which may be bolted to the basin floor or weighted with ballast to prevent buoyancy from carrying the pipe to the water's surface. The piping network consists of a vertical drop pipe, typically metal, a manifold, either plastic or metal, and a plurality of air distribution headers.
FIG. 1 is a section view of a complete Disc type Quick Connect Diffuser Assembly with mounted on pipe.
FIG. 2 is is a section view of the Saddle components of the Disc type Quick Connect Diffuser Assembly.
FIG. 3 is a plan view of the Upper Saddle section with the bayonet fitting for disc or tube diffusers.
The present invention relates to a system for aerating and/or mixing sewage, industrial wastewater, or related liquids contained within a basin which may be referred to as a tank, lagoon or channel. The basin is typically a concrete, steel or earthen structure.
An air blower or compressor supplies air to the invention through a network of steel and/or plastic pipes and fittings. Such pipes include out-of tank air supply pipes, vertical drop pipes into the tank(s), manifold pipes installed on or near the basin floor, and header pipes 3, which are installed perpendicularly to the manifold pipes. The header pipes 3 may be constructed of polyvinyl chloride, however they may be stainless steel, galvanized steel or other plastic material such as polypropylene, ABS or another plastic. The header pipes 3 are typically 4″ nominal diameter, however they may be from 2″ to 8″ in diameter.
In accordance with the present invention, a plurality of air diffusers 8 are connected with the header pipes 3 with a special bayonet mounting saddle shown in FIG. 2.
