SINGAPORE: An Indian-origin scientist has developed the world's first water purification technique that uses apple and tomato peels to remove different types of pollutants. In a bid to make clean water available at low cost, Ramakrishna Mallampati, a PhD student at the National University of Singapore, experimented with peels of apples and tomatoes. He found that tomato peels can remove different contaminants in water , including dissolved chemicals , dyes and pesticides, and can also be used in large-scale applications. It was also found that apple peels can remove dissolved water pollutants through adsorption.
Mallampati hopes that the water purification methods can benefit communities living in places where there is little electricity or resources to establish a water purification plant.
