Researchers at the University of Colorado-Boulder have developed a new membrane water filtration system based around air bubbles that aims to help address water scarcity issues around the world.
Membrane filters generally use pressure to force water through a sieve to separate out unwanted particles and contaminants. The new membrane system is unique in that it uses a tiny layer of air bubbles to distill the water rather than sieve it. This change makes the system more permeable and better at removing unwanted impurities than the common reverse osmosis systems working today.The new technology is described in a recently published journal
