A BOD5 analysis was conducted to assess oxygen demand of thewastewater. A 2.5 mL wastewater sample was transferred into 50 mLBOD jar which was made to the mark with aerated dilution water. Theaerated dilution water was prepared by allowing distilled water tostand in contact with clean compressed air until saturated with O2.The diluted wastewater sample was then incubated for 5 days at 20°C. After 5 days the dissolved oxygen concentration was determinedto be 4.33 mg/L O2. Report the BOD5 for the wastewater sample.
