Lighting the path to safer water with a new high-performance Hallett series

On October 1, UV Pure will launch its new reliable, self-cleaning Hallett™ series at WEFTEC 2018 in New Orleans. UV Pure’s new Hallett 1000 model joins the existing family of Hallett systems to provide advanced UV disinfection for potable water, wastewater, water reuse, and rainwater harvesting in municipal, industrial, and commercial applications.

The new Hallett family includes re-designed models from Potable, Wastewater, Reuse and NC product lines.

Hallett NC replaces the Upstream™ product line for applications that don’t require formal certification to NSF/ANSI standards or performance validation under US EPA and NWRI testing protocols.

UV Pure’s new Hallett Potable models provide the highest level of reliability and protection for public and private drinking water systems, including the most challenging applications for hard and mineral-rich water. Multiple smart sensors continually monitor UV dose, lamp intensity, and UV transmittance (UVT), and they can trigger an alarm or shut down the system entirely if treated water quality does not meet specified thresholds.

The Hallett PN series includes models that are certified to NSF/ANSI standards (pending), while Hallett 1000P systems will be validated to meet the US Environmental Protection Agency’s (EPA) globally accepted protocols for UV water disinfection. Water industry professionals rely on these designations for assurance that UV disinfection equipment provides the highest level of pathogen inactivation, public health protection, and regulatory compliance.

UV Pure’s new Hallett Wastewater product line ensures effective disinfection of domestic and industrial wastewater with UVT as low as 35% to minimize pre-treatment requirements. As with all of our systems, the new Hallett W-models incorporate a unique vertical, non-contact design with dual air-mounted UV lamps in an elliptical-reflector reactor chamber to concentrate sterilizing UV energy on wastewater from 360 degrees. The quartz sleeve continually cleans itself with an automatic wiper that prevents the buildup of biofilm and mineral scaling. The Hallett design enables lamp changes to be completed without the risk of coming in contact with wastewater in the quartz sleeve, and in much smaller spaces compared to conventional light-in-a-pipe systems.

UV Pure is also launching a new Hallett Reuse product line for disinfection of reuse water and rainwater. These Hallett R-models will be validated to provide an effective UV disinfection dose for low-UVT water from greywater and rainwater collection systems, and other reuse water from commercial and industrial applications.

Hallett 1000R systems will be validated to meet the National Water Research Institute (NWRI) and EPA protocols for UV water disinfection for UVT as low as 35%. This level of treatment assures public health protection under challenging conditions and significantly outperforms many conventional UV systems, which are often rated effective only for cleaner water with UVT above 75%.

New Hallett systems are still powered by UV Pure’s patented Crossfire Technology™

This technology features an automatic self-cleaning mechanism that continually removes minerals and biofilm from the quartz sleeve, thereby preventing fouling, maximizing UV dose delivery, and virtually eliminating the need for manual cleaning. Crossfire Technology also integrates multiple smart sensors that continuously monitor UV dose, lamp intensity, and net UVT for optimum performance.

The new Hallett systems will be launching at WEFTEC 2018.

Discover the NEW Hallett 1000: Smart new features, same trusted name

Operators can now virtually eliminate concerns about maintenance, active supervision, and performance reliability for on-site UV disinfection at commercial, industrial, and municipal water or wastewater plants up to 1 million US gallons per day (3,785 cubic metres per day). How?

UV Pure’s new Hallett™ 1000 systems have more capacity than ever, plus the performance, power, and smart technology you expect from UV Pure.

The new Hallett 1000 model builds on the success of UV Pure’s proven Hallett 30 system and patented Crossfire Technology™. This technology uses a unique elliptical reflector design with dual air-mounted lamps to deliver a high UV dose and target pathogens from 360 degrees.

New and improved features of the Hallett 1000

Longer lamp life:

Each Hallett 1000 unit is equipped with high-output, long-life low-pressure high-output (LPHO) amalgam UV lamps that are powered by a UL-certified pre-heat ballast with a soft start. This helps extend their operating life to provide maximum UV output for up to 12,000 hours, or approximately 16 months.

Larger capacity system, same reliable disinfection:

The new Hallett 1000 units can handle flow rates of up to 100 gpm (378 L/min) per unit while continuing to provide robust, reliable disinfection under the toughest conditions. For higher flow applications, multiple Hallett 1000 units are connected with a prefabricated pipe manifold to achieve flow up to 1 MGD (3,785 m3/day). This modular design provides built-in redundancy and ensures the highest level of protection since one or more Hallett systems can be shut down for service while others continue to operate.

Space-saving, easy-access vertical design:

The new Hallett 1000 systems incorporate a newly designed aluminum outer shell with side hinges that can easily be flipped open to access the internal components. This design even further reduces the Hallett installation space requirements on a wall or as part of a vertical-mounted manifold system, and allows operators to quickly change lamps without having to pull them from the fragile quartz tube.
