Become an Environmental Engineer: Design a Filtration Device
by Priti Mehta
Students identify the problem with drinking water contamination due to pesticide, prescription medicine, and hormones. They design solutions for a real-world problem that negatively affects the environment. Using chlorine as a proxy for other contaminated materials found in water, students design and test the filtration device that removes contamination efficiently. They use plastic tubes and assorted materials such as activated carbon, felt, sand, and cloth etc. to create filters. They also use water quality test strips to assess their success and redesign for improvement.
