Science & Tech Spotlight: Wastewater Surveillance

Why This Matters Wastewater surveillance can be an efficient way to detect community-level disease outbreaks and other health threats. It has the potential to identify a COVID-19 outbreak 1 to 2 weeks sooner than clinical testing and allow for a more rapid public health response. However, the lack of national coordination and standardized methods pose … Read more

Wastewater provides a planet-wide laboratory for the study of human health – BIOENGINEER.ORG

Of the many contemporary conveniences often taken for granted in developed countries, modern sanitation may be among the most important. A new study suggests that wastewater infrastructure may provide societal benefits far beyond the dramatic improvements in community hygiene. Of the many contemporary conveniences often taken for granted in developed countries, modern sanitation may be … Read more

A ‘greener’ way to clean wastewater treatment filters – BIOENGINEER.ORG

Membrane filters do not require much energy to purify water, making them popular for wastewater treatment. To keep these materials in tip-top condition, they’re commonly cleaned with large amounts of strong chemicals, but some of these agents destroy the membranes in the process. Now, researchers reporting in ACS Applied Materials & Interfaces have developed reusable … Read more

Graphene sensor rapidly detects opioid metabolites in wastewater – BIOENGINEER.ORG

Chestnut Hill, Mass. (2/25/2022) – The unique properties of the atom-thick sheet of carbon, known as graphene, enabled a new penny-sized, multiplexed bio-sensor that’s the first to detect opioid byproducts in wastewater, a team of researchers from Boston College, Boston University, and Giner Labs report in the latest online edition of the journal ACS Nano. … Read more

A novel evaluation framework for energy neutrality potential of wastewater treatment plants – BIOENGINEER.ORG

Towards China nationally determined contribution to carbon neutrality 2060, it is necessary to consider wastewater treatment plants. This kind of municipal facility consumes huge amounts of energy and emit greenhouse gases to remove pollutants. The three main pathways for decarbonization of plants include energy reduction, energy recovery, and energy renewables. Energy neutrality would be primary … Read more

Tracking seasonal and tidal effects on wastewater pollutants in the River Ganges – BIOENGINEER.ORG

A new analysis of the River Ganges in West Bengal, India, highlights how wastewater flowing into the river impacts its water quality, and how that influence shifts with seasons and tides. Sayanti Kar of Jadavpur University and Asutosh College in Kolkata, India, and colleagues present these findings in the open-access journal PLOS Water on February … Read more

Wastewater monitoring for public health – BIOENGINEER.ORG

Since September 2020, at the University of California, Davis, researchers have been monitoring wastewater on the UC Davis campus and in the city of Davis for COVID-19 through the Healthy Davis Together program. A new article published on February 8 in Proceedings of the National Academy of Sciences considers their experiences and the benefits and … Read more

University of Missouri scientist helps detect novel SARS-CoV-2 variants in NYC wastewater – BIOENGINEER.ORG

First delta, then omicron. The latest Covid variants have spread like wildfire across the globe in recent months, leading many scientists to wonder when the next variant will appear. Now, scientists may be one step closer to making that determination. First delta, then omicron. The latest Covid variants have spread like wildfire across the globe … Read more
