•
Removal of large amount of oil
and suspended solids from
wastewater.
Effluent requirements are
typically 100 -300 ppm oil and
TSS.

Treatment Objectives
•
Treatment objective is typically 30 to 5 ppm oil,
dependent upon discharge requirements, or
downstream treatment processes.
•
Dissolved Air/Gas Flotation Separator (DAF or DGF
Separators) –Most Common-pre-dissolves Gas in
WastewaterInduced Air/Gas Flotation Separator (IAF or IGF
Separators) Gas is Dispersed into Small Bubbles in
Wastewater.
