Abstract
Apparatus for the dispersed gas flotation and separation of insoluble, dispersed contaminants from a liquid comprised of a horizontal series of flotation cells, separated by baffles that permit the substantially horizontal flow of liquid from one cell to the next, each cell being equipped with one or more gas dispersing nozzles and screens which aid in the coalescence and flotation of the contaminant particles, and an inclined baffle above the horizontal series of cells to urge the floated impurities toward a weir positioned to remove the impurities from the surface of the liquid.
