Organic Contaminants

Derived from animals and plants, or may be manufactured chemical compounds. However, all organics contain carbon. Organic contaminants can be biodegradable, which means that the contaminants can be consumed by bacteria and other microorganisms. In the process of being consumed, these organics will exert an oxygen demand (BOD) which can be measured as the Biochemical Oxygen Demand (BOD) of the wastewater. Some organic contaminants (refractory organics) are resistant to biodegradation.

  • (BIO10) Estimating Sludge Volume (2343)

Organic Material

  1. Relating or belonging to the class of chemical compounds having a carbon basis.
    • (BNR01) Nitrification and Denitrification – An Introduction to Nitrogen Removal (1485)
  2. Material which comes mainly from animal or plant sources. Organic wastes generally can be consumed by bacteria and other small organisms.
