Notes: All Calculations are rounded
up, For Soil Porosity use: Sand
(loose=0.46, mixed=0.4; dense: uniform=0.34, mixed=0.3) Clay (soft=0.55,
stiff=0.37).
|
|
For Soil COD Test Method, Call BioRenova
|
|
|
Yellow boxes indicate
variables to be input by user.
|
|
|
Chemicals of concern that degrade aerobically and their
Stoichiometric demand can be added so to determine total oxygen demand
required and approx. cost of material.
