"The Impact of Nano-sized Pores on Filtration Technology"

Originally Published 1 year ago — by Phys.org

Researchers have demonstrated that the placement of nanosized holes on nanoporous membranes can significantly impact their performance in filtering impurities from water and other applications. Computer simulations revealed that the proximity of nanopores can affect water permeability and salt rejection, with a hexagonal pattern showing greater performance than a honeycomb pattern. These findings provide insight into designing more efficient nanoporous membranes for processes such as water desalination.

Reverse Osmosis: The Misunderstood Water Purification Method.

Originally Published 2 years ago — by WIRED

A study published in April by Yale’s environmental engineering program has replaced the “solution-diffusion” model of reverse osmosis with a “solution-friction” theory that water molecules travel in clusters through tiny, transient pores within the polymer, which exert friction on them as they pass through. This breakthrough could help people design membrane materials or structures that make desalination more efficient or better at screening out undesirable chemicals, and improve municipal water systems.
