Complete biodegradation of a newly-synthesized chemical in a wastewater treatment plant (WWTP) eliminates the potential for novel environmental pollutants. However, differences within- and between-WWTP microbial communities may alter expectations for biodegradation. WWTP communities can also serve as a source of unique consortia that, when enriched, can metabolize chemicals that tend to resist ...

As a result of uncontrolled discharge of wastewaters containing high levels of phosphorus to the receiving bodies could create adverse effects on water quality. Therefore phosphorus should be eliminated prior to discharging into aquatic environment together with carbon and nitrogen to reduce eutrophication risk. Control of effluent phosphorus level by enhanced biological methods became a standa...

Energy and water are inextricably linked, and together they are the two of the most valuable global resources. Internationally, the links between the energy, wastewater and water sectors are attracting increasing attention. In the wastewater sector, pressures including increasingly stringent environmental regulations and greater volumes of wastewater being produced and treated are a major chall...

The occurrence of eight carcinogenic N-nitrosamines in biosolids from 74 wastewater treatment plants (WWTPs) in the contiguous United States was investigated. Using liquid chromatography-tandem mass spectrometry, seven nitrosamines [(N-nitrosodimethylamine (NDMA), N-nitrosomethylethylamine, N-nitrosodi-n-propylamine (NDPA), N-nitrosodibutylamine, N-nitrosopyrrolidine, N-nitrosopiperidine (NPIP)...

The reuse of treated municipal sewage ('biosolids') on land is an effective method to divert waste away from landfill and to use an alternative, low cost method of fertilisation. While legislation has mainly focused on the control of nutrient and metal application rates to land, other potentially harmful emerging contaminants (ECs) may be present in biosolids. Up to 80% of municipal sewage slud...

Co-treatment of landfill leachate and sewage in a traditional wastewater treatment plant (WWTP) is a very common leachate management method in the United States. However, biologically recalcitrant and humic-like leachate organic matters (the major fraction of mature leachate organics) cannot be truly removed by the aerobic biodegradation in WWTPs. Prior to effluent discharge from WWTPs, chlorin...

The occurrence, fate and environmental impact of 30 pharmaceuticals including sulfonamides, fluoroquinolones, tetracyclines, macrolides, dihydrofolate reductase inhibitors, β-blockers, antiepileptics, lipid regulators, and stimulants were studied in two municipal wastewater treatment plants (WWTPs) located in Wuxi City, East China. A total of 23 pharmaceuticals were detected in wastewater sampl...

An assessment of the concentrations of thirteen different therapeutic pharmaceutical compounds was conducted on water samples obtained from different wastewater treatment plants (WWTPs) using solid phase extraction and high- and ultra-high-performance liquid chromatography with mass spectrometry detection (HPLC-MS/MS and UHPLC-MS/MS), was carried out. The target compounds included ketoprofen an...

This study aims to shed light on a new understanding of global machine-learning (ML) prediction models for wastewater treatment plants (WWTPs). The paper evaluates the development local and predict influent biochemical oxygen demand (BOD5) in four WWTPs. proposes an integrated framework remote sensing ML techniques, specifically decision tree, random forest, adaptive boosting, gradient boost al...

In recent years, there is a growing concern about the alarming spread of antimicrobial resistance (AMR) in different environments. Increasingly, many species bacteria, fungi and viruses are becoming immune to most commonly used pharmaceuticals. One causes development persistence these drugs, excreted by humans, municipal hospital wastewater (WW). Consequently, treatment plants (WWTPs) primary s...
