Clarifier Sizing
Spreadsheet
Below is a link
to a clarifier sizing spreadsheet developed by
Hydro-Flo Technologies.By inputting the major design criteria,
you can solve for the clarifier projected surface area and overall
clarifier volume.
The spreadsheet operates on Microsoft Excel 2003 or later.

What is the Process Flow Rate |
100.00 |
|
|
|
|
|
|
|
What is the Desired Hydralic Loading Ratio |
0.39 |
|
NOTE: The hydraulic loading ratio is
typically set from .25 to .5 The lower the settling rate or
specific gravity (of the settleable material) the lower the
hydraulic loading ratio.
Hydraulic loading ratios can be
determined by field tests or calculated based on the
specific gravity of the chemically treated solids. |

What is the Desired Plate Spacing |
1.93 |
|
| |
|
|
|
|
|
|
NOTE: Plate spacing can be set to any
number desired. The recommended low is .75" and the high is
usually 2" but higher can be specified if required by your
application. Plate spacing is usually determined by the
