Linking drugs of abuse in wastewater to contamination of surface and drinking water
The concentrations of 17 drugs of abuse, including cocaine, several amphetamines, opioid drugs, and 2 metabolites—benzoylecgonine, a metabolite of cocaine, and 2‐ethylidene‐1,5‐dimethyl‐3,3‐diphenylpyrolidine, a metabolite of methadone—were investigated in an urban watershed that is heavily impacted by discharges of municipal wastewater. The artificial sweetener sucralose was also monitored as ...

A modified anaerobic digestion process with chemical sludge pre-treatment and its modelling
Activated Sludge Models (ASMs) assume an unbiodegradable organic particulate fraction in the activated sludge, which is derived from the decay of active microorganisms in the sludge and/or introduced from wastewater. In this study, a seasonal change of such activated sludge constituents in a municipal wastewater treatment plant was monitored for 1.5 years. The chemical oxygen demand ratio of ...

Methane and nitrous oxide emissions from municipal wastewater treatment – results from a long-term study
Methane and nitrous oxide emissions from a fully covered municipal wastewater treatment plant were measured on-line during 16 months. At the plant under study, nitrous oxide contributed three-quarters to the plant's carbon footprint, while the methane emission was slightly larger than the indirect carbon dioxide emission related to the plant's electricity and natural gas ...

SARS-CoV-2 (Coronavirus) Detection in Wastewater
SARS-CoV-2 detection workflow in wastewater Monitoring wastewater for SARS-CoV-2 – or Coronavirus as it is more commonly known – can be a valuable data resource for an effective COVID-19 management. However, there are several challenges involved in detecting biological parameters in wastewater. Fortunately, there are also several solutions available to overcome them. Wastewater ...

Tracking Omicron With Wastewater Data
Testing wastewater for viruses can yield an unbiased epidemiological snapshot of an entire community Since early in the pandemic, wastewater-based epidemiology (WBE), also known as sewershed surveillance, has been used to track COVID-19. It’s a technique that detects chemicals or pathogens in a population by monitoring municipal wastewater, and it has a distinct advantage over individual ...

Real-Time Organic Loading Monitoring for Municipal Wastewater Treatment
Summary Operational decisions can be difficult to make when incoming wastewater quality fluctuates. Industrial manufacturers can discharge highly concentrated wastewater unexpectedly causing operational problems if not detected. Aside from potential operational problems, shock loading also has the potential to affect regulatory compliance if wastewater cannot be treated properly. Monitoring ...

A pilot-scale study on PVA gel beads based integrated fixed film activated sludge (IFAS) plant for municipal wastewater treatment
In the present study, a pilot-scale reactor incorporating polyvinyl alcohol gel beads as biomass carrier and operating in biological activated sludge mode (a combination of moving bed biofilm reactor (MBBR) and activated sludge) was investigated for the treatment of actual municipal wastewater. The results, during a monitoring period of 4 months, showed effective removal of chemical oxygen ...

5 Red Flags That Your Oil Skimming Solution Isn’t Reliable
Using an oil skimmer to remove oil from coolant, process water and wastewater has many benefits, such as reducing maintenance, lowering environmental impact, improving working conditions, and potentially creating new revenue opportunities. But, to reap those benefits, your oil skimmer must be completely effective, efficient, and reliable. In this post, we cover five signs that your oil skimming ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions - Case Study
Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
