Biological denitrification is a generally economically viable and reliable technology for nitrate (NO3−-N) nitrite (NO2−-N) removal from wastewater. Nitrate/nitrite reduction requires an electron donor, which can be supplied influent wastewater organic compounds, added as external carbon source, or by endogenous respiration. Decisions regarding the selection of source should take into consideration its cost, sludge generation quantity, rate efficiency denitrification, chemical storage safety. The expense waste management sources accounts up to 50% overall cost treatment. characteristics required biological affect microbial community structure, rate, intermediate products. This review based on bibliometric analysis systematic literature providing information insight topic process using different sources. In this review, main focus was discussing alternative vs. traditional in terms price, C/N ratio, operational parameters, advantages disadvantages, well limitations process. Future perspectives may include operating parameters influencing stability performance; maintenance improvement removal; study diversity community; research application new denitrification; N2O emission detection minimisation.
