Biochemical Oxygen Demand (BOD) Equations

Change Equation

Where

BOD = biochemical oxygen demand
L = ultimate biological demand
k = deoxygenation rate constant
t = time
D1 = initial diluted seeded wastewater dissolved oxygen
D2 = final diluted seeded wastewater dissolved oxygen
B1 = initial diluted seed sample DO
B2 = final diluted seed sample DO
f = seed volume ratio
P = wastewater decimal fraction
