LED UV Water Disinfection: A Chemical-Free Alternative or Supplement to Chlorine for Municipal Water Disinfection
LED UV water disinfection, used as the final stage in municipal water treatment, eliminates harmful pathogens like protozoa, bacteria, and viruses without the risks of chlorine or its by-products. By employing UV-C LED technology with an optimal wavelength around 280 nm, the PearlAqua Tera from LED UV-C Systems Ltd ensures safe, chemical-free water purification, either reducing or entirely replacing chlorine dosing. The LED UVC technology damages pathogen DNA/RNA, rendering them harmless, and provides a sustainable solution free from mercury-based lamps.

Why Choose the Tera LED UV System for High-Flow & Municipal Water Treatment?
The Tera LED UV system is the ideal solution for high-flow & municipal water treatment applications, offering energy efficiency, long-term reliability, and a lower total cost of ownership.
Unlike conventional mercury UV systems, which must remain on 24/7 due to warm-up times and operational limitations, the Tera LED UV system features instant on/off capability. This eliminates unnecessary power consumption when water demand is low—reducing energy waste and operational costs.
Designed with robust side-mount lamp modules available in 1-, 2-, or 3-module configurations, the Tera LED UV system delivers scalable performance for large-scale treatment. Its quartz-thimble-free design eliminates the risk of sleeve breakage and downstream contamination, ensuring reliable, continuous operation.
