Toilet paper is an unexpected source of PFAS in wastewater, study says
Sewage can provide information on potentially harmful compounds, such as per- and polyfluoroalkyl substances (PFAS), that get released into the environment. Now, researchers in Environmental Science & Technology Letters report an unexpected source of these substances in wastewater — toilet paper.
Daylong wastewater samples yield surprises
Testing the contents of a simple sample of wastewater can reveal a lot about what it carries, but fails to tell the whole story, according to Rice University engineers.
New Material Designed by Berkeley Lab ‘Mines’ Copper from Toxic Wastewater
A research team led by Berkeley Lab has designed a new material – called ZIOS (zinc imidazole salicylaldoxime) – that extracts copper ions from mine wastewater with unprecedented precision and speed.
NUS engineers turn pineapple leaves into biodegradable aerogels for food preservation and wastewater treatment
Researchers from the National University of Singapore developed a technique of using pineapple leaf fibres to create ultra-light, biodegradable aerogels. These versatile aerogels can be used for food preservation, wastewater treatment, oil absorbing as well as heat and sound insulation.
Pothole repair made eco-friendly using grit from wastewater treatment
Potholes can cause billions of dollars of damage every year to automobiles. Today, scientists report a new way to repair roads — by using a remnant of wastewater treatment called grit. They will present their results at the American Chemical Society Fall 2020 Virtual Meeting & Expo.
Harmful Microbes Found on Sewer Pipe Walls
Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak? A new Rutgers study, published in the journal Environmental Science: Water Research & Technology, examined the microbe-laden “biofilms” that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.
These tiny, self-assembling traps capture PFAS
A study shows hat self-assembling molecular traps can be used to capture PFAS — dangerous pollutants that have contaminated drinking water supplies around the world.
Novel Technology to Clean Wastewater Containing Explosives
A new grant from the US Department of Defense will help a University of Delaware team test a novel technology that uses iron nanoparticles to destroy munitions compounds in wastewater.
Treating wastewater with ozone could convert pharmaceuticals into toxic compounds
Researchers have found that ozone treatment and subsequent chlorination can convert trace amounts of some pharmaceuticals in wastewater into DBPs called halonitromethanes.
What’s in Puget Sound? New technique casts a wide net for concerning chemicals
Using a new “non-targeted” approach, University of Washington and UW Tacoma researchers screened samples from multiple regions of Puget Sound to look for potentially harmful compounds that might be present.
Study: How U.S. sewage plants can remove medicines from wastewater
A study of seven wastewater treatment plants points to two treatment methods — granular activated carbon and ozonation — as being particularly promising for reducing the concentration of pharmaceuticals including certain antidepressants and antibiotics.
