Below is
a link
to an "Enhanced Gravity
(DynaPak, CPI, TPI, Parallel Plate) Type Separator" oil water separator sizing spreadsheet developed by
Hydro-Flo Technologies. By inputting the major design criteria,
you can solve for the separation chamber's width to length to depth
ratios.
The spreadsheet operates on Microsoft Excel 2003 or later.

|
Qm
= design flow, in ft3 |
|
|
|
|

AH
= horizontal separator area, in ft2 |
|

|
|
j = oil droplet diameter in microns |
|
|
|
|
|

|
Sw
= specific gravity of the wastewater |
|
|
|
|
|
|
|
|
|
|
So
= specific gravity of the wastewater’s oil phase |
|
|
|
|
|
|
