1.0 OBJECTIVE

To measures the strength of the water sample (water, wastewater, etc) based on the amount of oxygen needed to stabilize the organic matter in the sample.

2.0 LEARNING OUTCOMES

i. The student will be able to describe the importance of BOD in the environmental studies.

ii. The students will be able to measure the BOD of samples with the right sample size.

3.0 THEORY

Biochemical Oxygen Demand is a common, environmental procedure for determining the extent to which oxygen within a sample can support microbial life. This method is popular in many environmental laboratories analyzing waste water, compost, sludge, and soil samples.

When a measurement is made of all oxygen consuming materials in a sample, the result is termed “Total Biochemical Oxygen Demand” (TBOD), or often just simply “Biochemical Oxygen Demand”. Because the test is performed over a five day period, it is often referred to as a “five day BOD”, or a [pic].

In addition, this procedure is only suitable for samples void of serious matrix interferences. To gain a broader appreciation of oxygen demand, additional avenues of interest may be explored including CBOD (carbonaceous oxygen demand),...
