When BOD is very low, the dissolved oxygen current within the water physique is large. This means that the water is considerably less polluted by natural and organic subject.Biochemical Oxygen Demand of a water sample is set by a Bioassay process that analyses the oxygen eaten with the bacteria in the decomposition of natural supplies over a durati

Occasionally by the end with the 5-day incubation time period the dissolved oxygen level is zero. This is especially true for rivers and streams with a great deal of natural pollution. Because It's not necessarily regarded when the zero stage was attained, it is not possible to tell what the BOD amount is.In contrast to lakes, where by DO amounts a
