How to calculate BOD value in a sample?
if unseeded, BOD = (D1-D2)/Pif seeded, BOD = ((D1-D2)-(B1-B2)f)/PD1 = DO of diluted seeded wastewaterD2 = DO of wastewater after incubationB1 = DO of diluted seed sampleB2 = DO of seed sample after incubationf = ratio of seed volume in seeded wastewater test to seed volume in BOD test on seedP = decimal fraction of wastewater sample used. (vol. of wastewater)/(vol. of dilution water plus wastewater)Maybe that helps
Are there limitations to the oxidase test?
There are none.
What are the main sources of error in a BOD test?
1. dilution error 2.blame the test sample 3.poor maintenance of bottles(cleaning)
Role of nitrifying bacteria in BOD test?
Nitrifying bacteria play a crucial role in the BOD (Biochemical Oxygen Demand) test. They are responsible for oxidizing ammonia to nitrate in the presence of oxygen. This helps determine the amount of biodegradable organic matter in a sample, as the oxygen is consumed during this process. By measuring the decrease in dissolved oxygen, the BOD test provides an indication of the organic pollution level in water.
