UV LED Water Disinfection
- UV LED Water Sterilization: Applications in Purification and Disinfection Systems
With the increasing scarcity of water resources, there is a growing need for water treatment methods that emphasize sustainability, non-toxicity, and effectiveness.
While traditional chlorination can be applied to tap water, it has limited effectiveness against certain resistant bacteria, such as Mycobacterium avium complex (MAC) and Pseudomonas aeruginosa.
In contrast, UV LED water sterilization technology provides an additional layer of protection, effectively inhibiting microbial growth and biofilm formation, achieving significant inactivation in a short period. It is an environmentally friendly and highly efficient water treatment solution.
-
Wavelength: 265–280 nm
-
Mechanism of Action: UVC light penetrates bacteria, viruses, fungi, and other pathogens, damaging their nucleic acid structures and preventing replication.
-
Safety Features: It does not alter the taste, odor, or clarity of water.
UVC light inactivates pathogens, rendering them harmless and allowing safe water usage. This makes UVC LED a reliable point-of-use disinfection technology.
Ultraviolet water disinfection provides a high-efficiency, non-toxic, and sustainable solution for water treatment.
Compared with traditional disinfection lamps, UV LEDs offer adjustable wavelengths, providing more targeted sterilization. Different pathogens require different wavelengths for effective inactivation.
