The textile way of purifying water

Inexpensive, portable and relatively uncomplicated – purifying water with the help of textiles has several advantages. Smart Textiles has developed two methods; one to remove microorganisms, and one to remove heavy metals. In the first, polluted water is channelled over a porous fabric coated with titanium dioxide; at the same time, the fabric is exposed to light (such as regular sunlight), kick-starting a reaction that destroys the cell membranes of the microorganisms and so kills them. In the second, the water is channelled over textiles, on the surface of which a special kind of fungus has been allowed to grow; the fungi bind to the heavy metals in the water, purifying it. One could say that an artificial microcosm of nature is created, in which nature and technology interact.
