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
