Device inspired by mangroves could help clear up flood water
A novel approach to removing salt from water, inspired by mangrove trees, has been revealed by researchers who say the system could offer an unusual approach to clearing up flood water.
Mangroves, like other trees, employ a system of water transport: it is thought evaporation of moisture from their leaves produces a negative pressure in their water-conducting tissues that helps to draw water into their roots and up their trunks.
This transport relies on surface tension, the fact that water molecules like to interact with the walls of the tissues, and that water molecules exert a “tug” on each other.
Salty water can damage most plants, but mangroves can thrive in salty conditions because they have adaptations including cell membranes that prevent salts from passing through in an uncontrolled manner, as well as cell walls that contain a waxy substance…
