This study evaluates the occurrence of flame retardants (FR) in five wastewater treatment plants (WWTPs) located close to Barcelona (NE Spain), an area with high urban and industrial pressures. Compounds studied include eight polybromodiphenyl ethers (PBDEs) and eight New Brominated Flame Retardants (NBFRs), for which little information regarding their presence, partitioning and fate within the...

Currently, energy and environmental efficiency are critical aspects in wastewater treatment plants (WWTPs). In fact, WWTPs are significant energy consumers, especially in the active sludge process (ASP) for the N-ammonia removal. In this paper, we face the challenge of simultaneously improving the economic and environmental performance by using a reinforcement learning approach. This approach i...

Introduction: Although various liquid, solid, and gaseous streams of wastewater treatment plants (WWTPs) have been analyzed in many studies for the presence of SARS-CoV-2 RNA, no study was found to sample and detect SARS-CoV-2 RNA in screenings and grit samples separated from primary treatment units of WWTP. Hence, this study aims to provide an experimental protocol for sampling and extracting ...

A total of 49 wastewater samples from 23 different wastewater treatment plants (WWTPs) were analyzed using real-time quantitative polymerase chain reaction for the presence and quantity of thermotolerant campylobacters. Thermotolerant campylobacters were detected in 87.5% (21/24) and 64% (16/25) of untreated and treated wastewater samples, respectively. Their concentration was sufficiently high...

A major challenge in designing resilient infrastructure is to meet the needs of sustainable development (Kennedy & Corfee-Morlot, 2013). Sustainable development requires a high degree of energy efficiency. Municipal wastewater treatment plants (WWTPs), in particular, have the potential to be much more sustainable. In the U.S., 3 – 4% of the total energy consumed is dedicated to WWTPs and drinki...

For many years, the “superbug” methicillin-resistant Staphylococcus aureus (MRSA) was confined to hospital patients, but since the 1990s it has been infecting otherwise healthy people in settings such as schools and locker rooms. Researchers now report the discovery of MRSA in U.S. wastewater treatment plants (WWTPs), identifying another possible environmental reservoir for the bacteria [EHP 12...

Policy of energy conservation and emission reduction has been advocated during recent years in China. The development of wastewater treatment has presented some problems with a huge sludge production and high operating cost. Eutrophication occurred frequently in many water bodies of China and discharge standards for wastewater treatment plants (WTTPs) are strict with nutrient removal. However, ...

Abstract. Urban wastewater treatment plants (WWTPs) as an important engineering facility for urban water pollution prevention and control, the appropriate location selection WWTPs is most stage in process of treatment. Improper site can lead to degradation environment. Phnom Penh located delta between Mekong River Tonle Sap River, with dense population, residents are religious. There no suffici...

The aim of the study was to determine the potential of community-level physiological profiles (CLPPs) methodology as an assay for characterization of the metabolic diversity of wastewater samples and to link the metabolic diversity patterns to efficiency of select onsite biological wastewater facilities. Metabolic fingerprints obtained from the selected samples were used to understand functiona...
