“…9 In this study, the authors presented the optimization of the support material diameter and bed porosity. Martínez-Jardines et al 10 reported the metabolic improvement and reduction of the inhibitory effect of 2-chlorophenol on nitrification processes performed in sequencing batch reactors. Likewise, Banda et al 11 performed physiological and kinetic evaluations of a denitrifying sludge using ampicillin as the only electron source, showing that denitrification processes allow the simultaneous oxidation of recalcitrant compounds and nitrate reduction during wastewater treatment.…”
