Raising the Bar for UV Water Disinfection with the New Hallett

Following years of development and testing, UV Pure launched the third generation of our popular Hallett UV water disinfection system. As we ramp up production to meet global demand, we want to share how the new Hallett makes safe water more accessible than ever.

Versatile UV water disinfection for diverse needs

The new Hallett offers the same reliable water disinfection for a wide range of applications. Our new product lineup includes models with varying capacities divided into three categories:

  • Hallett P models for potable water applications, such as commercial and residential use. The 500PN and 750PN are available with NSF 55A certification. The 1000P is available with EPA validation.
  • Hallett W models for wastewater applications, including industrial use. The 1000W is available with EPA validation.
  • Hallett R for reuse applications, such as in agricultural and recreational settings. The 1000R is available with NWRI validation for water reuse.

Third-party validation is pending for the Hallett 500 & 750 R, W models.

Our new Hallett 1000 models have been validated for US Environmental Protection Agency (EPA) performance standards for UV water disinfection to service markets that require EPA validation.

Larger, more powerful units

One of the exciting developments with the third-generation Hallett, is the introduction of high-capacity models. These models can handle flow rates up to 100gpm, up from the previous maximum of 30gpm. For applications requiring higher flows, like municipal water systems, multiple Hallett 1000’s can be connected to allow flows up to 1MGD.

For enhanced performance, these larger units feature amalgam lamps with higher output and an extended lamp life of up to 12,000 hours. Some larger models also come with quad UV sensors to support higher-accuracy measurements of UV dose and UV transmittance (UVT).

Smarter technology and improved design

Incorporating years of feedback from customers, technicians and our in-house experts has helped us make major technology and design enhancements in the new Hallett. Here are a few highlights:

  • UV dose display to enable hourly, daily, or weekly dose recording
  • A real-time clock to facilitate troubleshooting with time and date stamps for errors and warnings
  • A wiper position switch to accurately sense wiper movements in low UVT applications and optimize the wiper parking position
  • Data logging at 30-second intervals on a USB key
  • A double door hinge design to allow easier lamp changes and servicing of system components
  • Improved UV sensor housing to protect sensors during system handling and sensor calibration
Optimized performance and remote operation

Dependable performance is crucial to ensure that our Hallett systems can provide safe water in varying operating environments. That’s why the third-generation Hallett features forced-air cooling to prevent overheating and lamp heaters to enable use in extreme conditions.

Dependability also means that users can trust that their systems are running well, even when they’re not on site. Remote start/stop capabilities mean the new Hallett can remain on standby until a remote signal starts the UV system. The new models also provide more system information to remote operators, allowing them to prevent possible shutdowns ahead of any issues.

Delivering safe, clean water through innovation

Global demand for safe water continues to grow and innovations in water technology are rising to the challenge. As a pioneer in UV water disinfection, UV Pure continues to help customers meet their water needs across diverse industries, applications and markets.

Safety First: NSF and EPA Certifications for UV Water Disinfection

In this blog post, we examine the role of NSF and EPA certifications for UV water disinfection systems in ensuring water safety and providing peace of mind.

UV systems provide fast-acting, environmentally responsible water disinfection, making them an attractive alternative to chemical water disinfection.

As use of UV water disinfection grows, there is an important question to answer: how do end users know that a system works?

Navigating the certification environment

Given the importance of safe water, it is surprising that neither Canada nor the United States have federal regulations for UV water disinfection in residential settings.

The lack of mandatory standards does not mean there are no standards. For example, NSF International, a globally recognized organization, has created a set of voluntary standards for UV water disinfection technology  for home use.

There are different NSF standards depending on the function, size and end use of a product. While not required by law, many manufacturers of UV water disinfection products pursue NSF certification. This shows that their systems meet these minimum performance and safety standards.

The United States Environmental Protection Agency (EPA) is another source of standards for UV water disinfection for public water applications recognized worldwide.

Understanding the certification process

With end users placing their trust in certification, the testing process is understandably rigorous.

Broadly speaking, these are the key elements of the procedure for attaining certification:

  1. The manufacturer submits its UV water disinfection product and detailed documentation to a testing lab.
  2. Professionals at the lab thoroughly review the documentation. They gain a full understanding of how the product is designed and works, including all underlying technology and functional constraints.
  3. They then systematically test the product to ensure alignment between the documentation and actual construction and performance. This includes measuring performance against minimum standards, for example, consistent delivery of a minimum UV dose.
  4. The lab also carries out an inspection of the manufacturer’s production facilities to ensure they are up to standard.
  5. When the product meets all requirements, the product is certified for that specific standard.

Regular retesting and production facility inspections are required for a product to maintain its certification. In addition, re-certification is required any time a manufacturer makes changes to a product and each model must be certified separately.

For NSF certification, testing can be carried out in an NSF International lab or in third-party labs that test based on NSF standards. EPA does not offer its own testing services, so all testing to meet EPA standards is carried out by third-party labs.

Recognizing the value of third-party certification

Third-party certification can help you make an informed decision when purchasing a UV water disinfection system. Safety and reliability are essential no matter where you intend to use this technology. These requirements will be met with certification based on recognized industry standards.

UV disinfection systems intended for use at a public or commercial site (e.g. hospital, campground, hotel, etc.) generally require certification. In these settings, certification is essential for protecting public health, meeting compliance obligations and managing liability.

For residential use, the choice between certified and non-certified systems comes down to personal preference. While non-certified systems may come with a lower price, it is up to the end user to balance this against safety and reliability considerations.

Maintaining high standards at UV Pure

At UV Pure, safe water is our top priority. This commitment is reflected in our adherence to globally recognized safety and technology standards with most of our UV water disinfection products carrying NSF or EPA certifications.

The non-certified products we offer are made to the same high standards as our certified products.

When human health is on the line, there is no room for doubt. NSF and EPA certifications for UV water disinfection systems set the bar high, giving individuals and organizations around the world confidence that their water is safe.

The benefits of genuine UV Pure lamps

A UV lamp is a UV lamp… right? Perhaps it’s not as simple as that, especially when it comes to protecting public health from harmful waterborne pathogens.

UV lamps often provide the final step (and sometimes the only step) in water disinfection, so it’s critical that they are tested and certified to operate properly within your UV Pure system and to consistently deliver the required UV dose.

We’ve learned that there are non-genuine UV Pure lamps available, but installing these lamps can adversely affect treated water quality and system operation.

Major risks that you and your UV Pure system can encounter when attempting to use non-genuine lamps:

  1. Non-genuine UV lamps are not tested by UV Pure, or verified by third-party certifiers, to meet stringent performance specifications or water quality certification such as NSF/ANSI 55—putting the health and trust of those that depend on safe, clean water at risk.
  2. UV Pure lamps are designed and validated to provide maximum UV output for 9,000 hours, or about a year. Non-genuine lamps may not provide the same assurance.
  3. UV Pure smart controls and sensors may not perform as designed. These systems monitor and alert operators when lamps are approaching end of life and when lamp output drops below optimum performance.
  4. System water quality certifications will become invalid as UV Pure can’t assure system performance when non-genuine lamps are in use, or even after they have been removed.
  5. Sensitive electronic components such as control boards and ballasts may be adversely affected by non-genuine UV lamps, causing poor system performance, reduced component life or sudden component failure.
  6. Damage to UV Pure systems caused by non-genuine lamps cannot be claimed as a warranty repair and any remaining warranty will be void.
  7. Non-genuine lamps are not covered by UV Pure’s industry-leading one-year warranty.

How can you tell if a UV lamp is genuine?

Genuine UV Pure lamps are marked with the UV Pure logo and the UV Pure web URL at the base.

What to check when restarting UV Pure units for seasonal water systems

Are you getting ready to restart a UV Pure system at your seasonal property? Each UV Pure system is designed to make restart a simple process – almost as simple as flipping on the power and opening the water valve. To ensure optimum performance of your system, seasonal startup is a good time to perform a few simple inspections.

Before restarting your UV Pure system:

  1. Inspect the quartz sleeve for cracks, breaks and fouling.
  2. Inspect the reflector panels for damage.
  3. Inspect lamps for cracks and breaks.
  4. Inspect quartz around the filaments for discolouration at the ends, which indicates a bad lamp or a possible ballast issue.
  5. Reconnect all fittings and close all valves.
  6. Slowly apply water pressure and inspect the unit for any signs of leaks or loose plumbing joints.
    • If any components in steps 1 to 6 require attention, consult your manual or contact a qualified UV Pure service representative.
  7. When the system is fully pressurized, turn on the UV Pure system and allow the lamps to reach full power. This may take up to 24 hours.
  8. Once operational, flush water through the unit for at least five minutes.

Importance of having UV lamps:

We recommend making spare lamps available at each site to ensure uninterrupted system operation. UV lamps have a limited lifespan and should be changed after 12,000 hours of operation.

Your UV Pure system will alert you when:

  • the lamps require changing as they approach end of life, or
  • when lamp output has dropped below the optimum operating level. A menu screen in the LCD display of Hallet® and Upstream™ systems also shows the remaining lamp life.

Whenever changing lamps:

  • use only genuine UV Pure lamps to ensure the system meets certified performance standards and to avoid adverse effects to sensitive electronic components.

To understand all the benefits of using genuine UV Pure lamps, read this post.

For more information about restarting UV Pure systems, please see your instruction manual.
