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 […]

New polymer mat able to fish biologically harmful contaminants from water
There’s a new water treatment mat that acts like a miniaturized fishing net for water pollutants. Devised by Texan researchers, it can bait, hook, and destroy toxic chemicals in water supplies, according to a ScienceDaily article. Developed by the Nanotechnology-Enabled Water Treatment (NEWT) Center, the mat uses titanium dioxide to break down pollutants. It can be made as big or […]

Vitamin C can neutralize chlorine in water
While there are those who rely on chlorination for clean water, not many are aware that various studies have confirmed that chlorine is a toxic chemical. Exposure to chlorine can damage the arteries and weaken the immune system. Additionally, ingesting chlorine can cause oxidative stress in the cells and destroy fatty acids that are crucial to heart […]

South African wastewater found to contain heroin and cocaine; scientists say problem is worldwide
The results of a water test in South Africa revealed the last things that a person would want in their tap water. Researchers from the University of South Africa (Unisa) found heroin, cocaine, and traces of other drugs in wastewater collected from a provincial treatment plant in Gauteng. The team presented their findings at a […]

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 […]

The sewer system is collapsing at popular tourist destinations in Mexico… cholera won’t be far behind
We often think of the Yucatán peninsula as our own backyard paradise. Fly a little bit more north and you reach the island tourist destination of Holbox, a travel site known for its majestic beaches and inconceivable beauty. Annually, the state pulls in around 1,500 tourists during peak season. This is an impressive number considering […]

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 […]

Carbon nanotube material removes 99% of heavy metals from water
A set of innovative filters were found to eliminate up to 99 percent of heavy metals in contaminated water. The filters, produced in a Rice University laboratory, was developed from carbon nanotube materials that were grown in place on chemically-epoxidized quartz fibers. Lab findings showed that the filter was able to absorb more than 99 percent of metals from […]
