เครื่องจ่ายลม และหัวฟู่ (หัวจ่ายลม), ลูกยาง
The five-day test protocol with acceptably reproducible final results emphasizing carbonaceous BOD has been endorsed by The usa Environmental Safety Agency (EPA). This five-day BOD test result may be referred to as the level of oxygen necessary for aquatic microorganisms to stabilize decomposable organic subject below aerobic disorders.[7] Stabilization, With this context, may very well be perceived generally speaking terms as being the conversion of foodstuff to dwelling aquatic fauna. Though these fauna will carry on to exert biochemical oxygen demand from customers since they die, that tends to take place in just a much more secure evolved ecosystem including better trophic ranges.[3]
This was later on standardised at 68 °File and afterwards 20 °C. This temperature may very well be appreciably diverse within the temperature with the pure setting with the h2o being tested.
BOD values range between one mg/L for purely natural waters to about 300mg/L for untreated domestic sewage waters.
BOD test bottles in the laboratory of the wastewater treatment plant Biochemical oxygen desire (also called BOD or biological oxygen demand) is really an analytical parameter representing the amount of dissolved oxygen (DO) eaten by aerobic bacteria increasing on the natural and organic material current in a very water sample at a particular temperature around a specific period of time.
