BOD is biochemical oxygen demand. This is a better test but takes longer. COD is used to estimate BOD because BOD takes 5 days to complete. COD takes two hours.

Can I use titration to determine the oxidation instead of spectrophotometry?

Very informative 👏 👌 👍

Does COD also represent O2 needed to decompose anorganic contaminant?

@karl-uweschmitz3028 3 года назад

Dear Aris, COD is the oxygen amount required to oxidize organic matter into inorganic matter. It does not decompose inorganic components.

Can you elaborate what's "LO" referred at 0:56?

@karl-uweschmitz3028 4 года назад

Thanks for catching that. Its supposed to be "DO" for dissolved oxygen.

DO high BOD/COD values indicate high effluent values?

@adrianacuna7166 2 года назад

High BOD/COD means poor effluent quality

Free energy ఇస్తేనే ఫ్యాక్టోరీస్ వేస్ట్ వాటర్ ని ట్రీట్ చేస్తారా ? లేదంటే లేదా ?

Bro why is there 8000 in the formula ?

@hassanmahmoudi2752 2 года назад

HI what is LO?

@moehtaoni4249 4 года назад

Can I lower the COD by only injecting air into waste water?

@adrianacuna7166 2 года назад

By aerating, you're increasing aerobic bacterial activity its which removes COD
