Industrial Wastewater Treatment

What do firefighting foam, non-stick cookware, water-repellent textiles and pesticides all have in common? They all contain per- and polyfluoroalkyl substances, or PFAS—human-made chemicals that don't break down naturally. It's no wonder, then, that PFAS are now contaminating soil and water and can also be detected in the bodies of humans and animals. The dangers are well known: these forever chemicals can damage…

Given that previous studies have neglected the potential mechanism of the difference in aluminum content affecting the activated sludge system, a research team from Wuhan University of Technology has investigated the morphology distributions of residual aluminum salts (RAS) and their effects on the removal efficiency of activated sludge (AS) under different PAC concentrations, and revealed the internal mechanisms…

The Australian state of Victoria pulled out of hosting the 2026 Commonwealth Games on Tuesday citing major cost blow-outs, leaving organizers fuming as they scrambled to keep the multi-sport event afloat.State Premier Daniel Andrews said the initial estimated Aus$2 billion (US$1.36 billion) needed t...

Approximately 1,000 gallons of wastewater contaminated by the chemical trivalent chromium released into Coldwater Creek, which is also contaminated by radioactive waste from the first production atomic weapons in the

Using hydrogen and UV light, scientists reported destroying 95% of two kinds of toxic PFAS chemicals in tap water in under an hour.

A research team of environmental scientists from Ben-Gurion University of the Negev has developed a circular process for eliminating the risk posed by phosphoric acid plant wastewater. The process turns the environmentally toxic wastewater into clean water while recovering valuable acids. Phosphoric acid is the main ingredient in industrial fertilizers, a massive industry worldwide.

Efficient adsorbents for industrial wastewater treatment are important to minimize potential environmental damage. In particular, organic dyes, as a significant group of industrial pollutants, are usually highly water soluble, non-degradable and many are toxic to carcinogenic. Changxia Li and Freddy Kleitz from the Faculty of Chemistry of the University of Vienna together with colleagues now presented a new…

Minamata, a British film released in 2021, is based on the true story of an American photographer documenting how the citizens of Minamata, Japan, became ill due to the industrial discharge dumped into the river by a Japanese corporation. The Minamata disease, mentioned in the movie, is a neuromuscular disorder resulting from mercury poisoning. To prevent further human health impacts from mercury pollution, the…

Imagine millions of soapy sponges the size of human cells that can clean water by soaking up contaminants. This simplistic model is used to describe technology that MIT chemical engineers have recently developed to remove micropollutants from water—a concerning, worldwide problem.

Inspired by a common household cleaning supply — soap — MIT researchers synthesized micelle-laden hydrogel particles to remove micropollutants from water.

Nanorobots propelled by magnets can be used repeatedly without fuel, offering a sustainable and cost-effective way to clean up industrial wastewater

Pfas are poisoning our soil and polluting our lungs. The EPA is finally sounding the alarm – but that's not enough

Researchers in Japan have confirmed microplastics are present in clouds, where they are likely affecting the climate in ways that aren't yet fully understood.

They stop your food from sticking to the pan. They prevent stains in clothes and carpets. They help firefighting foam to extinguish fires. But the very thing that makes "forever chemicals" so useful also makes them dangerous.

An insidious category of carcinogenic pollutants known as "forever chemicals" may not be so permanent after all.

Without upgrading our wastewater management technology, our solutions will not overcome the issue of clean water access. Here are three tech innovations that can help us do that.

Danish startup Again has raised money… again. Google Ventures and Berlin-based HV Capital led the $43mn funding round, which brings the startup's total to date to just shy of $100mn. Again ...

A discovery by UC Riverside scientists could assist water providers across the nation as they face new federal standards to limit "forever chemical" concentrations in drinking water.

Refractory organic pollutants, including phenols, perfluorinated compounds, and antibiotics, are abundant in various industrial wastewater streams such as chemical, pharmaceutical, coking, and dyeing sectors, as well as municipal and domestic sources. These pollutants pose significant threats to ecological well-being and human health.
