Enhanced Gravity Oil/Water Separators Sizing Spreadsheet

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.

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))

SPECIFIC GRAVITY 0.8498498                
                   
Formula:                
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)
