Process for recovering entrained cellulose ester fines from scrubber-coolant water by forming a wet foam containing the fines, floating the wet foam upwardly in a vertically disposed foam flotation column and outwardly along a horizontal straight-line path from which liquid from the wet foam is drained and the fines are introduced in the form of a drier foam into a vessel for subsequent dissolving of the fines, with the horizontal straight-line path being pitched downardly from the horizontal plane.
