- Your application is potable water disinfection
- Budget is a primary consideration
- You want a proven, straightforward UV system
- Low total cost of ownership is important
Choose Hallett If…
Premium performance for challenging conditions
- Your water has low UVT, high hardness, or high iron
- You need NSF/ANSI 55, 61, or 372 certification
- Your application includes wastewater or reuse
- You require automatic self-cleaning

- You need modular redundancy for critical operations
Why UV Disinfection
The Advantages of Ultraviolet Treatment
UV-C light at 254nm destroys the DNA of bacteria, viruses, and protozoa — delivering safe, treated water without the downsides of chemical disinfection.
Chemical-Free
No chlorine, no byproducts, no chemical taste or odor. Just clean, safe water.
Broad Spectrum
Effective against bacteria, viruses, Cryptosporidium, Giardia, and other pathogens.
Low Operating Cost
Minimal energy consumption and simple lamp replacements keep costs predictable.
No Byproducts
Unlike chlorination, UV creates no disinfection byproducts (DBPs) like THMs or HAAs.
Instant Treatment
Water is treated in seconds as it passes through — no contact time or holding tanks needed.
Compact Footprint
UV systems require minimal floor space compared to chemical treatment alternatives.
Easy Maintenance
Annual lamp changes and periodic sleeve cleaning — that's it. No complex chemical handling.
Environmentally Safe
No chemical storage, transport, or disposal. A truly green disinfection solution.
