Industry Breakthrough for Mercury-Free Water Treatment
AquiSense Technologies has achieved what many in the water treatment industry considered a significant hurdle for UV-C LED technology – simultaneous validation under the US Environmental Protection Agency’s rigorous UV Disinfection Guidance Manual and certification to NSF/ANSI/CAN 61-2024 standards. This dual achievement marks a pivotal moment for advanced water disinfection systems, particularly those utilizing mercury-free LED technology.

The Kentucky-based company‘s PearlAqua Kilo system represents the first full-scale UV-C LED water disinfection product to meet both critical standards, positioning it as a viable alternative to traditional mercury-based UV systems for municipal and industrial applications.
Third-Party Validation Builds Industry Confidence
“These certifications represent more than just regulatory compliance – they demonstrate technological maturity,” explains AquiSense CEO Oliver Lawal. “Water operators now have independently verified evidence that LED-based disinfection can meet the most demanding performance requirements while ensuring material safety.”, according to further reading
The EPA UVDGM validation process involved extensive independent testing under varying water quality conditions, confirming the system’s ability to reliably inactivate chlorine-resistant pathogens including Cryptosporidium and Giardia. These microorganisms represent significant challenges for conventional water treatment methods and have been responsible for numerous waterborne disease outbreaks worldwide., according to recent research
Material Safety Meets Performance Excellence
The NSF/ANSI/CAN 61 certification addresses growing concerns about materials in contact with drinking water potentially leaching contaminants. This comprehensive standard evaluates products for hundreds of potential leachates, ensuring that water treatment components don’t introduce new health risks while removing biological contaminants., according to further reading
“The combination of disinfection performance validation and material safety certification creates a complete package for water utilities,” notes Jennifer Pagan, AquiSense’s Chief Technology Officer. “Municipal engineers no longer need to choose between innovative technology and proven reliability.”
Technical Advantages of UV-C LED Systems
The PearlAqua Kilo system leverages several inherent benefits of UV-C LED technology that differentiate it from conventional mercury-based alternatives:
- Instant On/Off Capability: Unlike mercury lamps that require warm-up time, LEDs provide immediate full-power disinfection
- Reduced Maintenance: LED systems typically offer longer operational lifespans with more predictable performance degradation
- Mercury-Free Operation: Eliminates environmental concerns associated with mercury lamp disposal and breakage
- Compact Design: Modular LED configurations enable more flexible installation in space-constrained environments
Broader Implications for Water Treatment Industry
This validation milestone comes at a critical time for the water treatment sector, which faces increasing regulatory pressure to address emerging contaminants while improving energy efficiency. The successful certification of a full-scale UV-C LED system demonstrates that LED technology has progressed beyond laboratory applications and small-scale point-of-use systems.
For municipal water utilities, the availability of certified LED disinfection systems provides new options for facility upgrades and new construction projects. The technology’s modular nature also offers potential benefits for distributed treatment approaches and emergency response applications where rapid deployment and reliability are essential.
As regulatory agencies worldwide continue to tighten standards for both water quality and environmental impact, mercury-free disinfection technologies validated to established performance standards are positioned to play an increasingly important role in protecting public health while supporting sustainability goals., as detailed analysis
