May 22, 2006 #3 cfj104 Civil/Environmental Apr 18, 2005 50 0 0 CA BOD is typically calculated over a 5-day period (BOD5) This is the simple calculation: BOD5 = (DOi - DOf)/P DOi = Initial dissolved oxygen DOf = Finial dissolved oxygen P = dilution factor = volume of wastewater/(volume of wastewater + dilution water) I would imagine a laboratory would use a seeded test to make sure there is an adequate bacterial population to carry out the biodegradation.
