The hard to degrade organics present in Some systems also might just take extended than 5 days to stop working, so a BOD exam will give an inaccurate measurement check here of the amount of pollution That could be existing in a very waste stream.
Thanx for your contribution for my dilemma. And There may be any normal values for BOD/COD ratio to establish the kind of the waste water?
BOD is a evaluate of, the level of oxygen that involve with the bacteria to degrade the natural factors existing in water / waste water.
