Deep sea pressure reverse osmosis at 400 to 600 meters drives membrane filtration, cutting energy use more than 50 percent ...

(Nanowerk News) A new method for preparation of a double-layered nanoporous membrane suitable for virus filtration was developed by researchers at Pohang University of Science and Technology in South ...

An international collaboration led by Kobe University researchers has successfully developed a nanosheet-laminated photocatalytic (*1) membrane that demonstrates both excellent water permeance and ...

The limited freshwater sources and the ease of water pollution necessitate efficient treatment systems. Membranes are commonly employed as filters and quality control materials in water treatment ...

Membranes with microscopic pores are useful for water filtration. The effect of pore size on water filtration is well-understood, as is the role of ions, charged atoms, that interact with the membrane ...

In a study published in Nature Chemical Engineering, researchers at EPFL developed a scalable method for producing porous graphene membranes that efficiently separate carbon dioxide. A graphene ...

Depth filtration or centrifugation? The choice is mainly a matter of economics. Depth filtration makes sense up to about 4,000 L, depending on the process, after which most biomanufacturers turn to ...
