The overall objectives of this research were two-fold: (1) to compare denitrification rates for organisms using different external carbon sources; and (2) to investigate acclimation of biomass to the various external carbon sources.
Denitrification Kinetics Using External Carbon Sources: Methanol, Ethanol And Acetate
External sources of organic carbon are often added to biological processes to facilitate denitrification and nitrogen removal by providing energy and carbon to heterotrophic bacteria. External carbon is needed especially in post-denitrification systems where wastewater carbon is not normally available. One of the factors in selecting an appropriate substrate source is that denitrification rates differ depending on the type of carbon added.
