Cellulose-Based Membrane Purifies Water in Minutes

Cellulose-Based Membrane Purifies Water in Minutes
Oct-21-15
A new method of filtering salty water in minutes could prove particularly beneficial to people living in remote areas.

The technique, developed by a team from the University of Alexandria, is based on an established method called pervaporation. However, until now the membrane used in this technique was complicated and costly to manufacture.

To make the pervaporation process more accessible, the team created a membrane embedded with cellulose acetate powder. Meant to replace the original, expensive membrane, the cellulose-embedded membrane is able to quickly desalinate and purify even polluted seawater. And because the water to be purified can be vaporized using fire, the membrane is suitable for use in remote areas.
