Flotation Process In Water Treatment

Wastewater Treatment Using Dissolved Air Flotation

However, the feed water is not always dosed with a coagulant. Thus, some DAF water treatment equipment lacks the chemical dosing system. After leaving the chemical feed station, the wastewater treatment moves into the flotation tank, which is the central part of the process engineered water equipment. Air Drum

Flotation In Water Treatment | SpringerLink

Abstract. In potable water treatment, sedimentation is the most widely used prefiltration process for removing readily settleable solids. However, many raw water sources contain low density particles such as algae which have a tendency to float thus causing problems at the sedimentation stage.
