A team from the Korea Institute of Science and Technology (KIST) and Myongji University, both located in Seoul, has published a new paper describing an “electricity generation and purification membrane for water recycling.”Continue ReadingCategory: Tec… Continue reading Water purification membrane generates electricity as it filters
Solar stills provide a clever and simple means of purifying dirty or salty water, but they work at a rather slow rate. A new material has been shown to boost their performance, and it’s made from fruit waste which would otherwise be discarded.Continue … Continue reading Simple process converts fruit waste into water-purifying material
Although we’ve seen a number of systems that use sunlight to purify tainted water, their output is often quite limited. A new loofah-inspired hydrogel, however, uses sunlight to treat much more water in one go … enough to meet a person’s daily needs.Co… Continue reading Sunlight-activated “loofah hydrogel” excels at purifying water
Scientists in Australia have developed an intriguing new technique for removing toxic “forever chemicals” from water. Adding a solution to contaminated water coats the pollutants and makes them magnetic, so they can easily be attracted and isolated.Con… Continue reading Magnetic solution removes toxic “forever chemicals” from water in seconds
Microplastics are a growing environmental problem, but now researchers in Korea have developed a new water purification system that can filter out these tiny fragments, as well as other pollutants, very quickly and with high efficiency.Continue Reading… Continue reading High-efficiency water filter removes 99.9% of microplastics in 10 seconds
PFAS are among the most insidious pollutants, thanks to their ubiquity, their long life and their growing list of linked health concerns. But now researchers at the University of California, Riverside have developed a new method to break them down more… Continue reading Hydrogen and UV breaks down toxic PFAS “forever” chemicals in water
While the purification of wastewater once just involved the removal of traditional pollutants, it now also entails the removal of microplastic particles. A new powder reportedly does the job much quicker and more thoroughly than has previously been pos… Continue reading “Nanopillared” material removes microplastics from water via magnetism
In wastewater produced by the textile industry and others, dye is one of the primary pollutants. A newly developed synthetic polymer is capable of removing that dye from the water, plus it can be cleaned up and reused to treat more wastewater.Continue … Continue reading New polymer removes dye from wastewater, and can be reused afterwards
When cooking oil is extracted from peanuts and sunflower seeds, a waste product known as oilseed meal is left behind. New research shows that proteins harvested from that meal can be used to filter heavy metals out of contaminated water.Continue Readin… Continue reading Low-cost filters use plant waste to remove heavy metals from water
Although there are already portable systems that create drinking water by desalinating and purifying seawater, they typically utilize filters that have to be replaced. A new MIT setup, however, just requires a small amount of electricity to get the job… Continue reading Filterless portable device uses electricity to make seawater drinkable
