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
There are many parts of the world in which fresh water may be plentiful, but it’s also full of harmful microbes. An experimental new filter is able to purify such water for drinking, and it’s powered solely by sunlight.Continue ReadingCategory: Good Th… Continue reading Sun-powered water filter excels at killing pathogens
Presently, in order to purify wastewater, antibacterial chemicals and ultraviolet light are among the measures commonly used. According to a new international study, however, the utilization of algae may be a more eco-friendly and energy-efficient alte… Continue reading Algae-purified wastewater used to raise fish
Access to clean water is a major unmet need in many parts of the world. Researchers at the University of Texas at Austin have developed a new hydrogel tablet that could help, with a prototype able to disinfect a liter of river water in one hour.Continu… Continue reading Purifying hydrogel tablet makes river water drinkable within an hour
Is there anything graphene can’t do? Researchers at MIT have found yet another use for the over-achieving wonder material, by making a reusable filter out of graphene oxide foam that acts like a magnet for uranium, effectively pulling the radioactive e… Continue reading Charged graphene foam acts as “uranium magnet” for water purification
In many arid regions, people use devices known as solar stills to extract drinkable water from seawater or tainted water. A new type of solar still is claimed to be much more effective than others, by incorporating a rotating cylinder.Continue ReadingC… Continue reading New solar still uses a rotating cylinder to produce more potable water
Ironically, many of the places that most require water purification have the least-developed infrastructure. That’s where a new filtration device comes in, as it’s activated by the sun – and it’s said to perform better than other solar-powered purifica… Continue reading Spongey filter releases purified lake water when set in the sun
Although ozone is often used to disinfect water in settings such as treatment plants, the required equipment is typically too large for use in small appliances like water coolers. A new miniaturized ozone generator, however, may be about to change that… Continue reading Tiny ozone generator could find use in water-purifying appliances
