Resilience of carbon and nitrogen removal due to aeration interruption in aerated treatment wetlands

Modeling the relationship of aeration, oxygen transfer and treatment performance in aerated horizontal flow treatment wetlands

“…The influent shows typical water quality of high strength primarily treated domestic sewage (Tchobanoglous et al, 2003) (Table 3). During Phases 1-3 ( Figure 4), both wetlands produced high quality effluents similar to effluent quality reported from previous experiments at the site (Boog et al, 2018) and the literature (Ilyas and Masih, 2017). Effluent concentrations and porewater patterns (…”

Recent Advances in the Application, Design, and Operations & Maintenance of Aerated Treatment Wetlands

“…Recovery of nitrification was observed on the order of days, which is much shorter than that observed in start-up of new aerated wetland systems, where establishment of nitrifying bacteria resulting in stable nitrification can take on the order of weeks to months depending on temperature. A follow-up study on an aerated HF wetland and an aerated VF wetland in Germany took a deeper look into the resilience of aerated wetlands in terms of carbon and Water 2020, 12, 1188 7 of 21 nitrogen removal [84]. Both HF and VF aerated wetlands were able to fully recover after simulation of air pump failure in both summer and winter conditions (water temperatures of >18 • C and <10 • C, respectively).…”

Optimization of the step feeding ratio for nitrogen removal by SBR using technique for order preference by similarity to ideal solution (TOPSIS)

“…Furthermore, one of the most important control parameters for biological nitrogen removal is the concentration of dissolved oxygen (DO). Complete nitrification and organic carbon removal can be achieved by providing high DO concentration [17]. On the other hand, denitrification potential was declined with a high level of DO concentration in the water [18][19][20].…”
