Removal
Primary Oil Water
Separation
Primary Oil/Water Separator
• Removal of large amount of oil and suspended solids from wastewater.
• Effluent requirements are typically 100 -300 ppm oil and TSS.
• API Separator –Most Common• CPI Separator

Secondary Oil / Water Separation
Secondary Oil/Water SeparationTreatment 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 Wastewater-
• Induced Air/Gas Flotation Separator (IAF or IGF Separators) Gas is Dispersed into Small Bubbles in Wastewater.
• Walnut Shell Filter –Least Common

Tertiary Treatment
• Typical Applications• Provide additional treatment to meet strict wastewater
discharge requirements.• Provide additional treatment to allow wastewater to be
reused.
• Typical Treatment Methods• Filtration Membranes• Activated Carbon
