BOD measurement of comparative thin

BOD measurement of comparative thinking in the form of water oxygen Because of the blinding bacterial microorganisms (Bacteria) to water they use in the process of decomposing organic matter (organic) By Find out the difference of oxygen dissolved in the water sample that measured the first day
With the oxygen supply Solubility in water samples collected in the same control cabinet temperature (incubator) 20 ± 1° C.5 days (DO5)

BOD = DO0- DO5
