What information is required to automate biochemical oxygen demand?

Home / FAQ / What information is required to automate biochemical oxygen demand?

Automating the biochemical oxygen demand (BOD) test can greatly increase the efficiency and production capacity of a laboratory. To automate this analysis, the following information is required:

  • How many bottles on average do you set up for an initials batch?
    • For example, this accounts for all samples and all dilutions per sample, plus blanks, GGA’s, etc.
  • How often do you set up Initials?
    • For example, many laboratories set up Initials on Wednesday, Thursday, and Friday then Finals on Monday, Tuesday, and Wednesday since the laboratory is closed on weekends.
  • What is the maximum number of bottles in your incubator at any one time?
  • Do you analyze BOD, cBOD, or both?
  • What is the source of most samples that you are analyzing
    • For example, municipal WW, industrial WW, surface water, etc.
  • What percentage of samples do you know the approximate BOD of before analysis?
  • Who are the clients or users of the BOD information?
    • For example, industrial pre-treatment, WWTP effluent compliance, WWTP engineers, etc.
