Cleaning Our Water with Nanotechnology


“Cleaning Our Water with Nanotechnology” is a public presentation about our drinking water and how we can make contaminated water safe to drink using a variety of technologies – including 3 new nanotechnologies for water purification. During the presentation, audiences consider the following questions: Which contaminants do we have in our water that makes it unsafe to drink? How do we typically purify our water – and what are the shortcomings/limitations of those technologies? How can new nanotechnologies purify our drinking water in new ways to help us in situations where large-scale water treatment isn’t appropriate? The presentation includes a variety of demonstrations to illustrate how these technologies work and some models to help visitors visualize what’s happening with these technologies at the nanoscale.
