· ,High, levels of five-day biochemical oxygen demand (BOD5) and ,chemical oxygen demand, (,COD,). BOD5 is a 5-day bio-assay type test and can be considered a measure of biodegradability as it relates to ,wastewater, treatment. ,COD, is a chemical degradation test that takes a few hours to complete and is used as a surrogate to BOD5.

The COD of wastewater with limited VFA (e.g., 10 mg COD/L) increased up to 2,502 mg COD/L where propionic acid (2,468 mg COD/L) exists as the primary end product with a small quantity of acetic acid (34 mg COD/L). Propionic acid was the main VFA component fermented from the glycerol addition. Glycerol addition led to increased RBCOD accompanied by high VFA production.

Almost all wastewater treatment plants are required to measure one of these three items as a measure of the pollution value in the water. COD should always measure higher than TOC and then BOD. COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized.

Chemical oxygen demand, (,COD,) relies on chemical oxidation with chromic ,acid, (a strong oxidizer). Many organic compounds, including color bodies and fibers, which are not easily biodegradable, along with any inorganic chemicals will show up as ,chemical oxygen demand, but not biochemical oxygen demand (BOD). Some mills have found that filtered ,COD, samples give a …
