“…Responsible editor: Gerald Thouand * Anne-Claire Texier texierac@yahoo.fr In the literature, there are various studies on the inhibitory effects of phenolic compounds on nitrification and at the same time, on the metabolic ability of nitrifying consortia for oxidizing these aromatic compounds: phenol (Yamagishi et al 2001;Amor et al 2005;Silva et al 2011), o-cresol (Jemaat et al 2014), p-cresol Beristain-Cardoso et al 2011), 2-chlorophenol (Martínez-Hernández et al 2011;Pérez-Alfaro et al 2013), p-hydroxybenzaldehyde (Téllez-Pérez et al 2013), and p-nitrophenol (Jemaat et al 2013). Most of these studies were focused on the simultaneous elimination of ammonium and a unique phenolic compound and the information on the simultaneous oxidation of mixtures of ammonium and diverse phenolic compounds is still limited, especially in bioreactors.…”

“…Because of their complex chemical composition, these wastewaters represent a great challenge for their disposal and treatment (Silva et al 2011). Actually, there is a growing interest to develop technologies for the biological treatment of effluents containing ammonium and phenolic compounds (Jemaat et al 2013(Jemaat et al , 2014. Phenolic compounds (phenol, cresols, chlorophenols, etc.…”

The aim of this study was to evaluate the physiological and kinetic capacities of a nitrifying consortium to simultaneously oxidize ammonium (138 mg N/L day), m-cresol, o-cresol, and p-cresol (180 mg C/L day in mixture) in a sequencing batch reactor (SBR). A 1-L SBR was firstly operated without cresol addition (phase I) for stabilizing the nitrification respiratory process with ammonium consumption efficiencies close to 100 % and obtaining nitrate as the main end product. When cresols were added (phase II m-cresol (10, 20, and 30 mg C/L); phase III m-cresol (30 mg C/L) and o-cresol (10, 20, and 30 mg C/L); phase IV a mixture of three isomers (30 mg C/L each one)), inhibitory effects were evidenced by decreased values of the specific rates of nitrification compared with values from phase I. However, the inhibition diminished throughout the operation cycles, and the overall nitrifying physiological activity of the sludge was not altered in terms of efficiency and nitrate yield. The different cresols were totally consumed, being o-cresol the most recalcitrant. The use of SBR allowed a metabolic adaptation of the consortium to oxidize the cresols as the specific rates of consumption increased throughout the cycles, showing that this type of reactor can be a good alternative for treating industrial effluents in a unique reactor.

“…In that configuration, the first aerobic granular reactor allows ammonium to be oxidized to nitrite by ammonia-oxidising bacteria and aromatic compounds to be totally biodegraded by specialized heterotrophic biomass [14][15][16]. In this sense, a suitable effluent for a subsequent anammox reactor can be achieved: (i) a nitrite/ammonium ratio close to 1.0 and (ii) no presence of organic matter [14,15].…”

“…The application of a two-step granular process to treat high-strength ammonium and aromatic compounds wastewaters has been recently proposed [14][15][16].

The short-term effect of several aromatic compounds (o-cresol, p-nitrophenol, o-chlorophenol and quinoline) was evaluated over granular anammox sludge cultivated over 2 years in a Sequencing Batch Reactor (SBR). The anammox granular sludge had an average size of 1.0 ± 0.2 mm and was enriched in Brocadia sp. Specific Anammox Activity (SAA) batch tests with this granular biomass were carried out in the presence of o-cresol, p-nitrophenol, o-chlorophenol, quinoline and their mixtures. The anammox biomass was never exposed to the tested aromatic compounds, prior to the SAA tests. The concentration and the mixture of aromatic compounds had a strong effect over the loss of the anammox activity. The higher the concentrations of the aromatic compounds, the higher the reduction of the SAA. Quinoline and p-nitrophenol have a lower negative effect compared to o-cresol and ochlorophenol. The Luong inhibition model seems to adjust better the inhibition of anammox biomass by the tested aromatic compounds. Depending on the aromatic compound, toxic or inhibitory effect was measured. o-Cresol and o-chlorophenol caused a toxic effect whereas p-nitrophenol and quinoline produced an inhibitory effect. In general, synergistic effects were observed when mixtures of aromatic compounds were studied.

“…Simultaneous partial nitrification and phenolic removal have been reported in continuous airlift reactors with aerobic granular biomass [23], [24]. Continuous reactors can mitigate the toxic effect of the recalcitrant compound over the biomass, since the bulk liquid concentration in the continuous reactor is expected to be low [24].…”
