Evolution and functional analysis of extracellular polymeric substances during the granulation of aerobic sludge used to treat p-chloroaniline wastewater

Effects of wastewater type on stability and operating conditions control strategy in relation to the formation of aerobic granular sludge – a review

“…On the other hand, phylum Proteobacteria has an active role in damaging the organic compounds of phenolic or anillin. As can be seen in the phylum, Thauera can reduce the p-chloroaniline (Dong et al 2017), while Comamonas and Pseudomonas can reduce the anilin (Jang et al 2003) and Rhodoccus can reduce 2-fluorophenol (Rollemberg et al 2019). Jemaat et al (2014) emphasized that the genus Acinetobacter can be responsible for the biodegradation of ocresol in AGS.…”

“…The granules display poorer settling properties with decreased polysaccharide ratio at low SUAV but higher rate of nitrogen removal. Dong et al (2017) claimed that the evaluation of granules depends on several parameters of rapid-growing aerobic microorganisms at higher OLRs and requires more shear or shear off the surface of the microorganisms, while less shear is needed at lower OLRs.…”

“…Kong et al (2015) claimed that Chloroflexi and Bacteroidetes are rich in aerobic granules exposed to cefalexin. In contrast to conventional active sludge, it can be concluded that the AGS technology demonstrates good achievement in treating wastewater including flammable organics, such as phenolic, dye, amine and pharmaceutical wastewaters (Chen et al 2007;Amorim et al 2014;Dong et al 2017).…”

An Efficient Bioaggregate Reactor for Enhanced Denitrification of Sewage with Low Carbon/Nitrogen Ratio

“…In addition, this peak shifted from 1060 (HRT = 2 h) to 1038 cm -1 (HRT = 4 h) and then 1033 cm -1 (HRT = 6 h), i.e., with increasing HRT, the amount of CH groups in the PS gradually decreased. The peak at 1635 cm -1 is related to C=O and C=C stretching vibrations in PN, which was reported to be beneficial to the aggregation of organisms [26].…”

Petrochemical slop wastewater treatment by means of aerobic granular sludge: effect of granulation process on bio-adsorption and hydrocarbons removal

“…This could promote the hydrolysis and biodegradation of the more recalcitrant fractions [2]. The bio-adsorption of some pollutants on cell surfaces of microorganisms forming aerobic granules, is mediated by the extracellular polymeric substances (EPSs) that help the binding of recalcitrant compounds with the biopolymers produced by microbial cells [21][22][23][24][25][26][27]. The treatment of petrochemical wastewater with AGS aroused interest of some researchers.…”
