1 BOD TEST An unseeded BOD test is set up with a dilution factor of 40 (1 ml of sample +39 ml. dilution water). The BOD bottle is then placed in an incubator with a digital temperature display reading 20C, as required. The DO measurements during the experiment were as follows: DOO - 8.6 mg/L (measured just before incubation started), DO: (end of third day of incubation) - 5.8 mg/L, DO. (end of sixth day of incubation) - 3.5 mg/L. (a) Determine the BODs of the sample (12 points): (b) If by accident the temperature indicator of the incubator used in the experiment was mot functioning properly and was showing temperature 5 degrees Celcius lower than the actual temperature in the incubator, adjust the results so that the value of BODs as reported at 20C (13 points) y = Lo (1-e); kr = kx 1.0563
