EPA Method 405.1:Biochemical Oxygen Demand. Official Name: Biochemical Oxygen Demand (5 days, 20oC)
Summary:The BOD test is an empirical bioassay-type test which measures the dissolved oxygen consumed by microbial life while assimilating and oxidizing organic matter in a sample. A waste sample (or dilution) is incubated for five days 20oC in the dark. Dissolved oxygen is measured before and after incubation using a modified Winkler or oxygen probe method (e.g., EPA Method 360.2 and 360.1). The reduction in dissolved oxygen during the incubation period yields a measure of BOD.
Scope:This test for BOD is used to determine the relative oxygen requirements of municipal and industrial wastewaters.
