Below is a link to an "Enhanced Gravity (MaxiSep, CPI, TPI, Parallel Plate) Type Separator" oil water separator sizing spreadsheet developed by HydroFlo Tech.
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.
Below is a sample shot of the spreadsheet.

|DENSITY OF THE WATER (IN G/CM³)||1.00|
|VISCISITY (IN POISE)||0.0113|
|RISE RATE OF OIL DROPLET (IN GPM/FT²)||0.0632|
|PROJECTED SURFACE AREA (IN FT²/FT³)||21|

|Use the formula below if you know the degrees API but not the specific gravity of the product to be removed|
|Conversion from Degrees API to Specific Gravity: Formula: Sw = (141.5 / (API + 131.5))|
|Qm / (AH * 7.48) = (j2 * 1.072 x 10 –6) (Sw - So) / m|
|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|
|m = wastewater’s absolute (dynamic viscosity, in poise)|
