TOD = COD + 4.57 * TKN, where
| |
TOD is the concentration of total oxygen demand
(mg/l)
| |
COD is the concentration of chemical oxygen
demand (mg/l) as determined by ASTM Testing Method D1252-00, and
| |
TKN is the concentration of total kjeldahl nitrogen
(mg/l) as determined by ASTM Testing Method D3590-02.
|
Actual pounds/month = total monthly flow (MG)
x Average sample TOD concentration x 8.34
| |
Where total monthly flow shall be provided by
the SIU and represents the flow for the covered calendar month.
