     While we've seen quite a few filtration systems for making polluted water drinkable, many are quite complex, or utilize costly materials. By contrast, an experimental new setup simply requires users to inject dirty water through a layer of cellulose.
    Developed by scientists from The University of Texas at Austin, the prototype device consists of a roughly hockey-puck-shaped housing, inside of which is a hydrogel film supported by a membrane full of microscopic pores.
The hydrogel is in turn made up of "an intertwined web" of cellulose nanofibers. Cellulose is the most common organic compound on Earth – it can be easily and inexpensively obtained from a wide variety of readily available natural sources, such as plants.
