  • Patent number: 5543043
    Abstract: Apparatus for clarifying produced water. A flotation chamber has a produced water inlet, a clean water outlet, and is segmented into a plurality of cells by baffles. An oil overflow compartment is in fluid communication with the upper portion of the chamber. Produced gas is introduced into each cell of the flotation chamber by porous sparger tubes creating bubbles of 100 to 1000 microns in diameter. The bubbles rise through the water removing any suspended oil particles. The gas exits through a gas outlet. The removed oil collects on the liquid surface of the produced water and overflows to the overflow compartment. Oil is removed from the overflow compartment via an oil outlet.
