Bhubaneswar: A girl from Odisha has won the 'Community Impact Award' at the prestigious Google Science Fair in California.
Reports said Lalita Prasida Sripada Srisai, a ninth standard student of Delhi Public School, Damanjodi in Koraput district developed a low cost bio-absorbent based water purifier which won her $10,000 as prize money.
Here's a brief explanation of her project:
Aquatic ecosystems support various life forms. Discharge of contaminants into water bodies is a matter of concern all over the World. Thus, the waste water released from different sources should be purified at source.
This project aims to clean waste water by flowing through different layers of corn cobs like long pieces of corn cobs, small pieces of corn cobs, powdered corn cobs, activated charcoal made from corn cobs and fine sand.
This is a cost-effective and simple technique. This is useful for immobilizing the contaminants in domestic and industrial effluents, and in ponds, reservoirs and water tanks.
Her project will receive support from Google for one year.
She has won the award in 13-15 years age group.
The winners of the fifth annual Google Science Fair were announced live from Google Headquarters in Mountain View, California. Lalita's school has said the water purifier will aid the poor who don't have access to clean water.
