  • What is dissolved organic nitrogen (DON) in wastewater treatment plants?
  • With the upgrade of wastewater treatment plants (WWTPs) to meet more stringent discharge limits for nutrients, dissolved organic nitrogen (DON) is present at an increasing percentage (up to 85%) in the effluent.
  • Which dissolved organic nitrogen is removed during anaerobic treatment?
  • The major removals of DON and biodegradable dissolved organic nitrogen (BDON) along the treatment train were observed in the anaerobic process. Dissolved combined amino acids (DCAA) and dissolved free amino acids (DFAA) in the effluent accounted approximately for less than 4% and 1% of the effluent DON, respectively.
  • What is dissolved organic nitrogen (DON)?
  • 1. Introduction Dissolved organic nitrogen (DON) is a faction of organic nitrogen that can pass through 0.1 μm pore size filters (Makinia et al., 2011; Czerwionka et al., 2012). Urea, amino acids, nucleic acids, humic and fulvic substances are the major DON compounds widely detected in the environment (Sipler and Bronk, 2015; Simsek et al., 2016).
  • Why is dissolved organic nitrogen a challenge in prechlorinated raw water distribution systems?
  • Sci. Technol.2025, 54, 3, 1484–1492 Dissolved organic nitrogen (DON) represents a unique challenge in prechlorinated raw water distribution systems (PRWDSs) because of its contribution to the formation of harmful nitrogen-disinfection byproducts, influence upon biogeochemical processes, and unclear molecular characteristics.
