floatation process in water treatment

Flotation in Water Treatment SpringerLink

Abstract. Dissolved-air flotation is a very effective solid-liquid separation process used in water treatment, as an alternative to sedimentation, to lower the solids concentrations before granular filtration. This enables filters to be operated more effectively and cost efficiently to

Lesson 14: Sedimentation and Flotation

2020-1-29  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.
