Water resource recovery facilities (WRRFs) performing biological nitrogen removal (BNR) often require external carbon sources for meeting discharge permit limits. This brings additional financial burden to the considering continuous need of these sources. paper evaluates utilization airport stormwater, which in winter season is rich aircraft deicing fluid (ADF) as an alternative source. Denitrification and nitrification bench scale experiments were performed after addition Experimental results showed that ADFs are able achieve denitrification rates (0.064-0.066 d-1) even slightly higher than commercial source tested (0.058 at low temperatures (as 13 °C) would be considered worst case scenario efficiency. Furthermore, no significant inhibition associated with was observed. Subsequently a dynamic modeling study conducted assess performance compared conventional being used full-scale BNR process. Results from revealed if 40% ADF applied LaGuardia airport, New York could collected stormwater conveyed WRRF via sewer collection system, approximate reduction 30% accomplished by repurposing waste product. contributes potential aid commercially available comparable efficiencies.
