Despite the widespread use of benzotriazoles and benzothiazoles and the occurrence of these compounds in wastewater treatment plants (WWTPs), no earlier study has comprehensively examined their fate in WWTPs. In this study, an integrated liquid chromatography-tandem mass spectrometry (LC–ESI(+)MS/MS) method was developed and validated for simultaneous determination of four benzotriazoles and fo...

The sequencing batch reactor (SBR) installed at Pt Pirie WWTP in South Australia is hydraulically overloaded due to significant ground water infiltration into the sewer network and requires additional treatment capacity. Modifying the operational parameters of Pt Pirie’s SBRs to select for granular sludge (GS) could be a viable means of increasing capacity. Through the use of a pilot-scale SBR ...

Bulking and foaming are two notorious problems in activated sludge wastewater treatment plants (WWTPs), which are mainly associated with the excessive growth of bulking and foaming bacteria (BFB). However, studies on affecting factors of BFB in full-scale WWTPs are still limited. In this study, data sets of high-throughput sequencing (HTS) of 16S V3-V4 amplicons of 58 monthly activated sludge s...

Micropollutants are emerging as a new challenge to the scientific community. This review provides a summary of the recent occurrence of micropollutants in the aquatic environment including sewage, surface water, groundwater and drinking water. The discharge of treated effluent from WWTPs is a major pathway for the introduction of micropollutants to surface water. WWTPs act as primary barriers a...

Environmental decision support systems (EDSSs) are an emerging tool used to integrate the evaluation of highly complex and interrelated physicochemical, biological, hydrological, social, and economic aspects of environmental problems. An EDSS approach is developed to address hot-spot concerns for a water quality trading program intended to implement the total maximum daily load (TMDL) for phosp...

This application note describes the creation of an accurate mass library for relevant environmental contaminants and its application for the screening of pesticides, pharmaceuticals and personal care products, their metabolites, and transformation products in effluents of municipal waste water treatment plants (WWTPs). An Agilent 1290 Infinity LC System coupled to an Agilent 6550 iFunnel Q-TOF ...

The structure of microbial consortia in wastewater treatment facilities is a resultant of environmental conditions created by the operational parameters of the purification process. In the research, activated sludge from nine Polish wastewater treatment plants (WWTPs) was investigated at a molecular level to determine the impact of the complexity of biological treatment line and the influent co...

Urban wastewaters (WW) are a major vector of many emerging pollutants (EPs) to aquatic ecosystems, as urban wastewater treatment plants (WWTPs) not designed abate them. New methods now critically necessary for more comprehensive analysis WW samples and the assessment WWTP efficiency in EP removal. To this end, present study aims develop methodology identify quantify EPs, especially pharmaceutic...

Nitrous oxide (N2O) is a greenhouse gas (GHG) emitted during biological nitrogen removal from wastewater treatment plants (WWTPs). Some modelling tools have been proposed to predict N2O emissions the design and operation of WWTPs. In this study, novel ASM2d-N2O model, which accounts for production in nutrient WWTPs, was used study associated full-scale WWTP with two independent lines. Firstly, ...
