For the past few decades, and increasingly today, ultraviolet (UV) radiation has been successfully used around the world for municipal wastewater disinfection. As a growing alternative and a direct replacement technology to chemical (chlorine) disinfection, UV does not produce harmful by-products and is non-toxic to the environment. Furthermore, UV technology is recognized as the “green” disinfection solution with a low environmental impact. TrojanUV is a global provider of UV disinfection systems, with decades of expertise behind them. Water Online spoke with Wayne Lem, TrojanUV market manager, to find out more about this important technology.
