Water Filtration Systems in Peru

Guest: Randy Lewis, Ph.D., Chair of the Department of Chemical Engineering at BYU  Floating on Peru’s famous Lake Titicaca near the city of Puno is a cluster of man-made islands. Some 1,200 people called the “Uros” live on the artificial archipelago made of thick reed mats that have to be regularly repaired and refreshed. It’s a precarious life, made more so by the lack of clean water for drinking. Yes, they’re surrounded by Lake Titicaca, but the waters are polluted by solid waste and sewage.
