Carbonaceous Biological Oxygen Demand (CBOD)

Presby Environmental - Carbonaceous Biological Oxygen CommandCBOD is the amount of oxygen, in mg/L, required by bacteria to oxidize the organic matter or biologic food available in the system. A high CBOD indicates that there will be very little dissolved oxygen available for fish and other aquatic life in the water system tested. This becomes more important if the wastewater will be released near surface water features such as lakes or streams.
