ABSTRACT:
A jet aeration header is disclosed, for use in water and wastewater process and treatment system. The header comprises a first pipe defining a cylindrical water passage, a second pipe extending parallel to the first pipe and defining a cylindrical air passage, at least one water outlet conduit connected to the first pipe to allow water to be expelled out of the water passage, an air-feed pipe connecting the second pipe to the outlet conduit to allow air to be delivered from the air passage to the water flowing through this conduit, and a venturi cone mounted in the outlet conduit to allow air to be FED from the air passage and be mixed with a water expelled through the outlet conduit. This basic structure is improved in that each outlet conduit is connected to the first pipe by a hollow nipple laterally projecting from the first pipe, the nipple having a large, flared inlet solidly connected to the first pipe in such a manner that no sharp edges or protrusions are left inside the water passage, that would favor fibrous materials to attach, accumulate and clog the outlet conduit. Each water outlet conduit is defined by the transverse bar section of a T-shaped pipe, the stem section of the T-shaped pipe being connected to the air-feed pipe. The venturi cone is mounted into the transverse bar section of the T-shaped pipe forming the conduit outlet so that the wide inlet of the venturi cone is adjacent the outlet of the nipple to which the T-shaped pipe is connected.
