How do we determine what the precision is at these degrees that happen to be 1-2 orders of magnitude reduce than the GGA level? In addition, the acceptance requirements for GGA are determined by the suggest moreover/minus only one conventional deviation.
Dilution Variable: Dilution Variable is definitely the ratio of the volume of the sample to the volume from the diluted sample. It truly is used inside the components of BOD if the sample is diluted for its volume reduction. Volume of Sample is the volume in the undiluted drinking water sample calculated in millilitres (mL).
BOD values vary from 1 mg/L for all-natural waters to about 300mg/L for untreated domestic sewage waters.
