## 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.
