<p>A liquid aeration device includes a head box having a bottom wall, a pair of spaced side walls interconnected with the bottom wall, and a pair of spaced transverse walls interconnected with the side and bottom walls to form a receiver chamber into which liquid to be aerated is fed and from which such liquid passes through orifice means formed in one transverse wall of the head box from whence the liquid by free fall passes through an entry chamber and enters a vertically disposed downcomer conduit interconnected at its bottom with a pressure chamber to which a vertically disposed riser conduit is also connected. A third transverse wall is interconnected with the side walls and spaced downstream somewhat from the transverse wall in which the orifice means is formed and since the head box is of the open top type, an excess of liquid which overflows the transverse wall having the orifice means is allowed to overflow the third transverse wall and to fall by free fall downwardly through the space adjacent the upper end of the riser conduit. If desired a second or more phases may be used and which would include the above described components.</p> |
