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.
