Influent Characteristics
**************************************************************************
NOTE: Insert maximum design flow and wastewater
characteristics which have been established by
direct measurement and chemical analysis.
**************************************************************************
Provide oil-water separator designed for a maximum flow of [_____] liters
per second gallons per minute. Operating temperatures of the influent
oil-in-water mixture will range from [_____] to [_____] degrees C degrees F
and ambient air temperatures will range from [_____] to [_____] degrees C
degrees F. The specific [gravity] [gravities] of the [oil] [oils] at
operating oil-water temperatures will range from [_____] to [_____]. The
specific gravity of the [freshwater] [freshwater and seawater] [seawater]
at operating temperatures will range from [_____] to [_____]. The average
specific gravity of the suspended solids is [_____]. The influent is
further characterized as follows:
**************************************************************************
NOTE: List additional types and concentrations of
detergents, anti-oxidants, solvents, acids or bases,
and heavy metals that may be present in the
oil-in-water mixture. If these additional items are
present: chemical addition, flocculation and
dissolved air flotation, or other appropriate unit
operations may be needed for effective treatment of
these constituents.

Performance Requirements
**************************************************************************
NOTE: Make choice based on standards or guidelines
established by environmental regulatory agency(ies);
or other design considerations, such as unit
wastewater treatment process(es) that follow
downstream from this separator. Quantity of free
oil removed is dependent on characteristics of
