Wastewater treatment plants catch a lot of the nastiness that swirls through our sewage and agricultural run-off before that water is reused. But those facilities tend to miss filtering out pharmaceutical drugs that make their way into wastewater.
One of those drugs is Diazepam — first marketed as Valium — a calming drug used to treat anxiety and seizures. It is commonly used and potentially addictive psychoactive drug that impacts how patients thinks and feel. Diazepam is sold under 500 different brands worldwide, and widely abused. So the fact that it both makes it’s way into wastewater, and is not properly filtered out, is a concern for the public health community.
In 2017, a study published by Rio de Janeiro State University found that both treated wastewater and untreated wastewater had the same concentration of psychoactive drugs. Traditional treatment methods aren’t getting the job done.
Now, researchers have developed a low-cost method to remove Diazepam from recycled water and wastewater. This new method uses titanium dioxide nanofibers to target Diazepam, and other two other […]
