A Flotation Process for Water Purification

Flotation is a method of concen-tration that consists of producing a hydrocarbon-like surface on nonhydro-carbon particles.* The process is selec-tive; the nonhydrocarbon particle be-comes hydrophobic, and may be re-moved from the water by bubble attachment and aeration. Usually, mineral particles in the size range from 1 to 400 [x are removed (6).Lesson 3: Sedimentation and Flotation,Lecture. Primary Sedimentation. Purpose. Sedimentation is a treatment process in which the velocity of the water is lowered below the suspension velocity and the suspended particles settle out of the water due to gravity.
