The solution is the fact in very clear samples (two hundred mLs or more of sample used) we need to increase more nutrients to make certain that bugs continue on to survive.
Incomplete Metabolism: Some complicated natural compounds may not be thoroughly metabolised by microorganisms inside the regular incubation period of time. This may end up in an underestimation from the BOD price, as the complete oxygen demand of the sample is probably not realised.
“In the event the BOD is 300mg/l and previously mentioned, sewage is claimed being nutritious, and if is 100mg/l or beneath it is alleged to be weak”. I doubt if this assertion is true, it should have been When the BOD is 300mg/l and over, sewage is claimed to generally be weak, and if is 100mg/l or beneath it is said being healthy
