Old biological filters work better than new water treatments, according to Swedish study
An old water treatment technology called slow sand filters could be making a comeback – and the older filters would work better than both newer ones or modern filtration methods. According to Science Daily, a Swedish study suggests that the older the filter, the better it is for treating water. Slow sand filters first appeared during […]

Cities that are running out of water can now safely remove at least some pharmaceuticals from recycled water and wastewater
If cities are forced to recycle water, they’ll need to find a way to filter out pharmaceuticals – such as the widely used anxiety drug Diazepam – from wastewater. So, South African researchers have developed titanium dioxide nanofibers that can remove drugs from water, reported ScienceDaily. The fibers are the brainchild of a research team […]

Engineers study self-assembling block polymer membranes as an alternative option for water treatment
As water scarcity spreads across the face of the Earth, researchers are scrambling for ways to convert non-traditional sources into potable water. In a Nano Werk article, engineering researchers from two universities reported that self-assembling block polymer membranes could be used as alternative materials in water filtration. The United Nations warned that about 1.9 billion […]

Silk hybrid material can attack bacteria when illuminated by a green light
Indiana and Korean researchers have found a way to fuse a far-red fluorescent protein into silk. When exposed to green light, the resulting material will release molecules that kill bacteria and other dangerous pathogens, according to a NanoWerk article. Touted to be all-natural by its creators, the new biomaterial offers an alternative way to sterilize pathogens. […]

Plastic pollution being re-purposed to break down dyes from wastewater
People use plastic for a variety of reasons, which has given way to the production of different kinds of the material. However, one of the unintended consequences of such an expansion is that of improper disposal. Experts have developed recycling methods to reduce plastic waste, in an effort to mitigate environmental damage. Now a joint […]

Science breakthrough removes nearly all BPA from water at very low cost
A team of researchers at Carnegie Mellon University, University of Auckland, and Oregon State University has recently developed a catalyst that effectively eliminates nearly all traces of bisphenol A (BPA) from water. The new catalysts, called tetra-amido macrocyclic ligands (TAML) activators are small molecules that are known to mimic oxidizing enzymes. According to the researchers, combining the […]
