ABSTRACT
The article focuses on the use of ultra-pure quartz glass in ultraviolet light (UV) water and air purification systems in the U.S. It states that the use of UV disinfection technology is helping make drinking water a more sustainable resource dues to the decline of readily available potable water in the world. It notes that the use of quartz is translating twice the amount of ultraviolet output compared to standard germicidal lamps, which inactivates common pathogens.
