IVIC researchers develop nanobubble system for water purification

Researchers at the Venezuelan Institute for Scientific Research (IVIC) have developed a nanobubble system designed to purify and disinfect water in tanks and reservoirs. Led by physicist Eric Plaza and materials engineering student Vanesa Uzcátegui from Simón Bolívar University, the technology aims to reduce reliance on chemical disinfectants like chlorine, ozone, or ultraviolet radiation.

The method utilizes a physical process combining ultrasound and electrolysis. By applying an electric current between two electrodes, the water decomposes to release hydrogen and oxygen at a nanoscale. These tiny gas particles inhibit the growth of harmful microorganisms and pathogens for extended periods without altering the water's chemical composition.

Laboratory tests have already shown positive results against two types of bacteria. The research team is currently systematizing data for scientific publication and working toward the development of a scalable prototype. If successful, the technology could be implemented in both industrial and domestic settings to prevent waterborne diseases and support public health initiatives.
