5 Day Biochemical Oxygen Demand Calculator
Posted by Dinesh onOnline calculator to calculate 5 day biochemical oxygen demand that estimates consumption (i.e. demand) of oxygen during the aerobic oxidation.
5 Day BOD Calculation
Formula:
BOD 5 = [D1 - D5] / P
where,D1 = initial sample dissolved-oxygen (DO) concentration,
D5 = sample DO after 5 days,
P = Dilution factor (decimal volumetric fraction of sample used),
BOD 5 = 5 day biochemical oxygen demand
