Hallett 13 Systems For Non-Potable Applications

UV Pure’s Hallett® 13 systems for Non-Potable Applications including Wastewater and Process Water up to 1 MGD, outperform conventional UV wastewater systems. Effective in treating very low quality wastewater, process water or grey water (low UV transmittance), are self-cleaning, and do not expose operators to potentially hazardous wastewater.


Hallett UV wastewater purification systems, with patented Crossfire Technology, are engineered for simple, efficient multiplex configuration, and treat flows up to 1 MGD (3785 m3/day) For Non-Potable Applications including Wastewater and Process Water. Hallett LPHO (low pressure high output) systems For Non-Potable Applications including Wastewater and Process Water outperform all conventional LPHO wastewater systems and most medium pressure systems with the ability to treat very low quality (low UV transmittance) wastewaters trouble free. Traditionally, low-quality wastewater effluents have required medium pressure systems to reach the required dose. The Hallett system For Non-Potable Applications including Wastewater and Process Water is the first of its kind and the only LPHO technology that matches and/or beats the performance of conventional medium pressure systems which are significantly more expensive from a capital and operating cost perspective. Each Hallett system For Non-Potable Applications including Wastewater and Process Water is factory sized and programmed to achieve target treatment requirements. Hallett systems are effective in a broad range of pre-treatment wastewater quality. They are also engineered to prevent operator exposure to potentially hazardous wastewater since no manual quartz cleaning is required.

UV Pure's Crossfire Technology uses dual smart UV sensors that continuously monitor UV Dose, Lamp Intensity (UVI), and net UV Transmittance (UVT). That means a disinfection dose 2.4 times greater than conventional UV systems for the same energy input and cost.

UV Lamp removal is fast, safe and easy on all UV Pure systems like this Hallett 30 system for wastewater and potable water treatments. There is no extra, wasted space required for lamp removal. Hallett's are equipped with UV Pure's patented Crossfire Technology.

Flexible stainless steel hook-up hoses mean no hard piping and are standard on all UV Pure Hallett wastewater and potable water treatment systems.


Only UV Pure's patented Crossfire Technology provides automatic mechanical self-cleaning eliminating quartz fouling from minerals and bio-film. It also prevents operator exposure to potentially toxic wastewater. With Crossfire Technology there is no risk of false alarms due to fouling.
