Mexican scientists deploy nanotechnology to clean up Xochimilco canals
MEXICO CITY (Reuters) – Mexican scientists have developed a unique “nanobubble” system using solar energy to improve water quality in the canals of Mexico City’s Xochimilco ecological zone, a popular tourist attraction.
Officials in Mexico City have been focused on cleaning up the long-polluted waters of Xochimilco, a UNESCO World Heritage Site and one of the few areas of the capital that still boasts canal networks dating back to Aztec times.
A team of researchers from the Center for Research and Advanced Studies (Cinvestav) has developed a method using solar energy to activate a pump that sends cleansing “nanobubbles” into the water…(more)
