Sentences with phrase «current water desalination»

Unlike the existing reverse - osmosis membranes responsible for more than half of the world's current water desalination capacity, the new membrane process dehydrates ions as they pass through the membrane channels and removes only select ions, rather than indiscriminately removing all ions.

Not exact matches

And desalination is just one niche of the water industry — but like others, it offers limitless opportunities for innovation, since many current technologies are outdated and inefficient.

Enormous investments in desalination of sea water technology and systems are expected in the years ahead as current desalination techniques are very energy demanding leading to significant CO2 emissions.

In experiments, the researchers pumped water through a graphene membrane treated with both defect - sealing and pore - producing processes, and found that water flowed through at rates comparable to current desalination membranes.

Recent promotion of desalination raises additional concerns regarding overall resource efficiency and the potential for diminishing returns on investment, given the energy inputs required to ensure water supply, with current energy supply being from thirsty fossil - based processes.
