Process simultaneously removes toxic metals and salt to produce clean water

"..."Desalination or water treatment plants typically require a long series of high-cost, pre- and post-treatment systems that all the water has to go through, one by one," said Adam Uliana, a UC Berkeley graduate student who is first author of a paper describing the technology. "But here, we have the ability to do several of these steps all in one, which is a more efficient process. Basically, you could implement it in existing setups..."

3D-printed graphene aerogel makes efficient, scalable water filter

"...Nanosheets of graphene have shown promise in water filtration in the past, but these are harder to produce at large scales. The team says that making graphene aerogels through this new technique makes them easier to scale up. They’re also reusable and apparently don’t leave residue in the water coming out the other side..."

Finally, 3D-printed graphene aerogels for water treatment

"..."The goal is to safely remove contaminants from water without releasing any problematic chemical residue," says study co-author Nirupam Aich, PhD, assistant professor of environmental engineering at the UB School of Engineering and Applied Sciences. "The aerogels we've created hold their structure when put in water treatment systems, and they can be applied in diverse water treatment applications. " The study -- "3D printed graphene-biopolymer aerogels for water contaminant removal: a proof of concept" -- was published in the Emerging Investigator Series of the journal Environmental Science: Nano..."
