Developing device to expand global access to safe drinking water
Update: The 窪蹋勛圖厙 team selected as bronze winner in the graduate competition. A team of student innovators from 窪蹋勛圖厙, developing a device to expand access to clean drinking water globally, was chosen a finalist in the 2018 (CIC) by the . Finalists will present their entries to a panel of judges composed of innovators from across the country, and have their inventions showcased at the CIC Expo at the United States Patent and Trademark Office (USPTO) headquarters in Alexandria, Virginia, Nov. 14-16.
The device
Solar disinfection, developed in the 1980s to inexpensively clean water, is simply filling a clear bottle with water and exposing it to sunlight for several hours to destroy bacteria and viruses. The approach is proven to reduce diarrheal disease, the second-leading killer of children younger than 5. Although solar disinfection is so effective that UNICEF and the World Health Organization have endorsed it, the technique can be difficult for users to know how long to treat their water to ensure it's safe. To address that uncertainty and speed the purification process, the team devised the Optimized Solar Purification with a Reusable Indicator, or OSPRI, a cheap, reusable, sensor that changes color when the water has received enough sunlight to be safe to drink. OSPRI is made of a dye-based formula contained in a tube that drops to the bottom of a water-filled bottle during solar disinfection. With our device, this underutilized technique becomes much easier to use, which will help it become practically accessible to a far wider audience, Datta said. What drives us is the potential to impact the health of so many people with a device that is so simple and affordable. Since we first started BBP, our goal has been to make our device accessible to as many people as possible. After nearly three years of development, BBP has a prototype water-disinfection technology that is ready for field-testing with the nonprofits partner in Nairobi, Kenya. BBP has grown from three co-founders to a group of more than 30 students, most of them from 窪蹋勛圖厙.For more information, contact Bill Lubinger at william.lubinger@case.edu.
