What does BOD measure? •The Biochemical Oxygen Demand is an empirical test that measures the amount of oxygen used by bacteria as they metabolize organic matter at 20 oCelsius, in the dark, usually over a 5 day period.•(pH 6.5 to 7.5 is best) •Two types
If using High Range Plus COD Digestion Reagent Vials, multiply the result by 10. For most accurate results with samples near 1500 or 15,000 mg/L COD, repeat the analysis with a

We explain the differences between biological oxygen demand & chemical oxygen demand. Yesterday afternoon I finished up some stormwater training with an old client of ours who changed some staff recently. I was brought in for some basic environmental training, and one of the topics we covered was their NPDES stormwater permit..
METHOD #: 410.1. Chemical Oxygen Demand (Titrimetric, Mid-Level) COD Chemical Oxygen Demand. 1.0 Scope and Application. 1.1 The Chemical Oxygen Demand (COD) method determines the quantity of oxygen required to oxidize the organic matter in a waste sample, under specific conditions of oxidizing agent, temperature, and time.
5. The sample vials was inserted into 16-mm. 6. READ the results in mg/L COD. 7. If High Range Plus COD Digestion Vials was used, the result was multiplied by 10. The most accurate results was samples near 1500 or 15000 mg/L COD, the analysis was repeated with diluted sample.
