Dilution Issue: Dilution Component could be the ratio of the quantity of the sample to the volume of your diluted sample. It truly is employed in the system of BOD when the sample is diluted for its volume reduction. Volume of Sample is the volume with the undiluted h2o sample measured in millilitres (mL).
Since chlorine is these types of a solid oxidizing agent, it can inhibit The expansion of living germs within the BOD test. Any samples containing residual chlorine should be pretreated to get rid of chlorine before the test is run. This can be accomplished by incorporating sodium sulfite towards the sample.
