Research on UVC LED wavelength dependency

ZAPARAY starts a research track on the UVC LED wavelength dependency on pathogen inactivation.


This biomedical research track is spearheaded by Hannah Siwe.

Hannah holds a master’s degree in Biomedical Sciences.

With her knowledge and experience in research, she will investigate ZAPARAY’s upcoming innovations in biocidal efficacy. This project runs in the Laboratory of Liver Infectious Diseases (LLID) headed by Prof. Dr. Philip Meuleman and Laboratory Bacteriology Research headed by Prof. Dr. Piet Cools, both at Ghent University. More specific she will investigate the biocidal impact of the technology change from UVC discharge lamps to UVC LED as a sustainable solution for virucidal and bactericidal water disinfection. UVC radiation originating from mercury lamps is already for over 100 years an important source of disinfection, however its severe environmental impact due to toxic mercury compounds and high energy consumption is an obvious driver towards alternative light sources. With the recent evolution of LED technology, it becomes more and more feasible to replace the mercury lamps by LEDs as UVC radiation source. ZAPARAY is a Belgian company specialized in the development and manufacturing of chemical-free disinfection solutions based on UVC LED radiation technology.
