A fluid conditioning system and method is disclosed for coupling to a first solution source comprising a suspension solution and particles suspended in the suspension solution. The fluid conditioning system includes a containment vessel defining a treatment environment and including a wall defining a fluid passage and having an inlet apparatus. The inlet apparatus is coupled to the solution source for receiving a solution stream and directing the solution stream through the passage helically along the cylindrical wall. The containment vessel includes a sparging apparatus disposed downstream of the inlet apparatus for introducing a gas into the solution stream, and an outlet for discharging the sparged solution stream. The system further includes a flotation tank disposed proximate the containment vessel outlet for receiving the discharged solution stream. The flotation tank is adapted to carry a predetermined volume of a second solution to effect flotation of the particles to the surface of the second solution. The flotation tank further includes a tank outlet for exiting processed effluent from the tank.

[ What is claimed is:] [1.] A flotation system for receiving fluid and separating particulate matter from the fluid, the flotation system comprising:a substantially vertical conditioning chamber having an upper end and a lower end and including a cylindrical wall defining a fluid passage, a fluid inlet adjacent the upper end for directing the fluid through the passage helically along the cylindrical wall, and an air inlet, the chamber being operative to mix the fluid and air together, the chamber further including an outlet adjacent the lower end for evacuating the fluid and air mix from the chamber;a floatation tank including an isolation unit having a plurality of spaced-apart vanes defining respective floatation cells between adjacent vanes; anda conduit connected to the outlet of the conditioning chamber and in fluid communication with the flotation tank at a location below the water level of the tank, so that the fluid and air mix is introduced to the flotation tank at a location below the water level in the tank.
