Lesson 14 Sedimentation And Flotation

The main process used in wastewater treatment is dissolved air flotation. Another flotation variant is electro-flotation. The two processes differ primarily in the way the gas bubbles are produced. Flotation is a unit process whereby particulate matter is separated from a wastewater, causing the matter to float to the liquid surface.
