Biochemical oxygen demand (Biochemical Oxygen Demand, BOD): analysis by the dilution water samples in a direct way with BOD bottle experiment is
1) Select, for example, the volume of water that is expected to give up the BOD (BOD in the table 3.1) by approximately 2 to 3
value) Measuring water samples based on the selected volume in the BOD bottles, 2 bottles volume
3) dilution water into bottles full BOD bottle. Close the cover and then the bottle back and forth, with a good mix
. 4) split into one collection Kit 2 value DO immediately (DO0) by Azide modification method to another curing cabinet temperature 20 degrees Celsius for a period of 5 days (bottle mouth with water, the casting and the dry evaporation water protection CAP)
.5) after 5 days and then taken to DO the rest (DO5)
6)
BOD values are calculated using the formula.
