Wastewater Dissolved Air Floatation (DAF)
The Dissolved Air Floatation (DAF) removes algae and suspended solids. As the wastewater enters the DAF tank, fine air bubbles carry the algae to the surface, where it is removed with a skimmer. The DAF is capable of removing sufficient algae to nearly meet the turbidity standards most of the time without the need for subsequent filtration. Filtration provides an insurance to meet the high discharge quality standards.
