Advanced UV Optoelectronics: Revolutionizing Large-Scale Water Disinfection with Deep Ultraviolet LED Technology
Advanced UV Optoelectronics: Revolutionizing Large-Scale Water Disinfection with Deep Ultraviolet LED Technology As the world grapples with escalating pressures on water resource management and public health security, traditional water treatment technologies are facing significant hurdles—including inefficiencies, high energy consumption, and risks of chemical residue. Data highlights the stakes: waterborne illnesses cost the global economy billions of dollars annually, underscoring the urgency for safer, more effective solutions. Conventional mercury-based UV lamps, long relied upon for disinfection, compound these issues with drawbacks like excessive energy use, short operational lifespans, and environmental hazards from mercury contamination—failings that increasingly clash with modern sustainability goals.
