15-year-old Srishti Asthana has been named among the top 15 finalists of the Google Science Fair, 2013. Her project on a Green Technique for treating water polluted with detergents competed against entries from across the world to make it to the finals. She proposes nano ZnO assisted photo catalytic degradation using solar light for the treatment of contaminated water.
Speaking to an English daily about her inspiration for the project, Srishti said, “As a part of a field trip, I went to Ludhiana last year and was taken aback to see how the dyes from the textile industries got drained out in the water bodies, thus polluting it. On querying from an owner on how they treated the water before draining out, he counter questioned me on whether do we treat the detergent water before draining that out. The question triggered an idea in me of doing the same.”
The advantages of her method as mentioned in her project are: fast reaction, short treatment time, less costs, less exposure for workers, complete reduction pathway to non-toxic end products is possible and less equipment.
The class XI student of science Stream from Millenium School in Mohali will showcase her project at the Google headquarters in the US on September 23 to present her project for the final round, which will be judged by an international panel of esteemed scientists. The grand prize will get a ten-day trip to the Galapagos Islands, $50,000 in scholarships, and more.
The Google Science Fair is an online competition. It was first started in 2011 and is open to students in the age groups of 13-18 to widen science projects and share their findings.
