ABSTRACT:
A machine which utilizes hydraulic effects to disperse gas bubbles throughout a contained liquid includes a feed duct mounted to introduce raw liquid into the contained liquid. The feed duct comprises a first hollow tubular member into which a stream of processed liquid is pumped. A second hollow tubular member is affixed outside, and concentric with, the first tubular member so that space is formed around the open end of the first tubular member. Raw liquid is introduced into the space between the two members, and the processed liquid aspirates the raw liquid through the feed duct.
