WebThe following data are provided to you: Seeded wastewater: Initial DO = 8.6 mg · L−1 Final DO (after 5 days) = 2.1 mg · L−1 Volume of wastewater = 2.5 mL Total volume in BOD bottle = 300.0 mL Seeded dilution water: Initial DO = 8.6 mg · L−1 Final DO (after 5 days) = 7.3 mg · L−1 Volume of seeded dilution water = 300.0 mL T = 20°C WebVolume of wastewater = 2.5mL Total volume of the BOD bottle = 300mL Seeded dilution water: Initial DO = 8.6mg/L Final DO (after 5 d) = 7.3mg/L Volume of seeded dilution water = 300mL Expert Answer 100% (3 ratings) To calculate Biological Oxygen Demand, we use the following formula : BOD= [ (D1-D2) - ( … View the full answer central hudson poughquag ny
Chapter 5: BIOCHEMICAL OXYGEN DEMAND (BOD)
WebDWK Life Sciences (Wheaton) BOD Bottle Racks are constructed of coated wire. 1215X63 is holds up to twenty 60 mL BOD Bottles and 1220C96 hold up to twelve 300 mL BOD Bottles. Rubber Leash For BOD Stopper (1234R64) ensures that the stoppers do not become lost when collecting samples in from the field. The 10 mm diameter…. WebThe bottle had an initial dissolved oxygen concentration of 9 mg/L, and a final dissolved oxygen concentration of 3.5 mg/L. A blank (a BOD bottle filled with dilution water) run in the parallel showed no change in the dissolved oxygen in the 5-day incubation period. The BOD reaction rate coefficient for the waste is 0.3/day. Webare16230.0 mg/L, what would be the ultimate BOD for each? 5) oA wastewater has a five-day BOD equal to 210 mg/L (test performed at 20 C) and an ultimate BOD of 350 mg/L. Find the five-day BOD at 25oC. 6) In a standard five-day BOD test, a. Why is the BOD bottle stoppered? b. Why is the test run in the dark (or in a black bottle)? c. central hudson powering the path
