Filtering water is an incredibly important process, but it's not as simple as it seems. As the pores in a membrane inevitably get clogged with material, it takes time and energy to clean or replace ...

A porous silicon membrane that is a few nanometers thick can quickly filter liquids and separate molecules that are very close in size, researchers at the University of Rochester report in this week’s ...

(Nanowerk News) Everyone knows it from their childhood days in the sandpit: sand is filtered using a sieve. Larger stones get stuck, while fine sand can fall through the sieve. The same principle is ...

A "straight out of science fiction" liquid membrane developed by a team of Penn State mechanical engineers acts as a "reverse filter" that lets large objects through while blocking small ones. The ...

Researchers just developed a revolutionary new graphene water filter that could provide fresh drinking water to millions of people around the world. The innovative design filters liquids nine times ...

Oil filtration media have at least two layers in practice, but typically three or more. Porous filtration materials like cotton, polyester, and non-woven fiberglass fabrics segregate particles from a ...

Filtering and treating water, both for human consumption and to clean industrial and municipal wastewater, accounts for about 13% of all electricity consumed in the US every year and releases about ...
