Identifying the New Third Generation Hallett Feature Advancements

When UV Pure® decided to redesign a new generation of Hallett, it defined what the best features and proven technologies are in the UV water disinfection world. The Third Generation Hallett hit the pavement running when it was first introduced to the market in March 2019 and hasn’t slowed down since.

What sets the Hallett apart from competing products, is its non-contact maintenance and easy to operate colour touch screen. This means the operator is not exposed to coming in contact with contaminated water when performing routine procedures, such as quartz inspections and lamp changes. In fact, the Third Generation Hallett design makes maintenance even easier.

To help visualize the advancements from the First and Second Generation Hallett to the new Third Generation Hallett, we have selected a few features to compare between the generations to better explain the improvements that have been made.

Automatic Quartz Sleeve Cleaning Mechanism

The automatic quartz sleeve cleaning mechanism has always been built into our product and always will be. The new door design allows for easier quartz inspection.

User Interface

The user interface has evolved significantly between Hallett generations. The First Generation Hallett had a single button interface, which was then expanded to four mechanical buttons for the Second Generation Hallett, and since then has developed to a multi-colour LED touch-screen display for the Third Generation Hallett.

The new onboard colour touch screen displays UV dose, a real-time clock, operating status and self-diagnostics. With improved message history capabilities, storage capacity has increased to the last 99 messages with real-time information that includes time, sensor values, temperatures, dose, UVT and UVI values at time of alarm.

Third Generation touchscreens display all most relevant information when treating:

        • System Model
        • Remaining Lamp Life
        • UV Dose
        • Maximum Flow
        • Date & Time

These latest advancements also lead to less time spent on operational troubleshooting. During warnings, the LED screen will turn yellow and display the active warning message, no longer requiring to search through message histories or manuals to understand what faults are being communicated. This will reduce operational downtime and service time of operators.

External Alarm Contacts

Focusing on efficiency and reliability, the Third Generation Hallett continues to provide two dry contacts for alarms or auto-dialers. The word “dry” typically indicates undetected voltage present at the contact. The first contact consists of a “System Run” condition, which upon being closed, indicates the unit is in treating mode, while if open, indicates the unit is in alarm, has lost power, or perhaps the wire has been damaged. The second contact labeled “warning” indicates the existence of an abnormal condition such as high-water temperature. If this contact is open, the system is operating under normality and if closed, a warning condition is presently communicated.

Remote Start/Stop

With the First and Second Generation Hallett’s not having the ease of the remote start/stop function, our team put high focus on adding this feature in the Third Generation Hallett. By having this feature built into the model, UV Pure can offer built-in redundancy when in parallel configuration.

Minimum UVT Required

In the UV disinfection world, we all understand the importance in having low UV transmittance (UVT). Our Third Generation Hallett 1000’s has one of the lowest UVT´s in the market. In the table below, you will see the minimum UVT required for our different models.

Hallett

Minimum UVT Required

Third Generation (H1000 series)

35%

Third Generation (H500, H750 series)

50%

Second Generation (H15xs, NC series)

50%

First Generation (H30, H13 series)

45%

 

Lamp Heaters

UV pure has improved its product performance in cold climates by installing lamp heaters into the H500 and H750 series of the Third Generation Hallett.

Lamp Change Duration

Changing the lamps in the Hallett models has always been easy, but now customers can change the lamps themselves! With the easy access to the lamps, it takes less than two minutes to change the lamps.

 

The new Third Generation Hallett models have NSF/ANSI certifications and third-party validation in accordance with the US EPA UV Disinfection Guidance Manual (UVDGM) and NWRI UV Disinfection Guidelines for Drinking Water and Water Reuse. With a small footprint and simple plug-and-play design, the Hallett is quick to install and easy to start up, even in the tightest of spaces.

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.

NSF logo

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.

Safe Water Technologies: An Introduction to UV Water Disinfection

Water is used everywhere, from agricultural and industrial to residential and healthcare settings and beyond. Whatever the specific application – whether it’s potable water, wastewater, reuse water, or rainwater – safety is paramount. Here is an introduction to water disinfection. There are many ways to make water safe for use, including various processes for filtration (nano, ultra, and reverse osmosis) and disinfection (chemical and non-chemical). The process or combination of processes used depends on factors, such as the initial water quality, intended end use, logistical and economic considerations.

In this post, we focus on ultraviolet (UV) water disinfection, providing an overview of how it works and how it is evolving.

The water disinfection landscape

In general, there are two main categories of water disinfection technology:

1. Chemical technologies, which include chlorine, ozone, and peracetic acid
2. Non-chemical technologies, which include UV disinfection

uv-water-disinfection-benefitsEach technology has a unique set of advantages and disadvantages. For example, chemical disinfection using chlorine is highly reliable and inexpensive, but it poses safety risks in the handling of chlorine and the creating toxic byproducts.

When deciding which technology is best for an application, engineers typically take into consideration a range of factors. Some of those factors include requirements for biocidal efficiency, practicality, reliability, cost, environmental impact and occupational health and safety.

Harnessing the power of UV light

UV water disinfection harnesses the germicidal power of short-wave UV light, specifically at the 254nm wavelength, to damage the DNA of cells and viruses. Applying UV light at this specific wavelength to water renders any microorganisms sterile, thereby disinfecting the water.

The first use of UV water disinfection technology was in 1910. Since then, the use of UV systems has grown as the technology has evolved along with scientists’ understanding of how UV light combats waterborne threats.

Compared to chemical disinfection technologies, non-chemical UV disinfection offers several key benefits in terms of safety and efficacy, including:

  • Fast-acting, triggering a reaction almost instantly
  • No disinfection by-products
  • Safe and chemical-free, avoiding the handling and disposal hazards associated with chemicals
  • Environmentally responsible technology
  • Does not alter water chemistry and its constituents, such as pH, taste, odour, colour, etc.
  • Proven and trusted

Different technologies for UV water disinfection

Since that first application, the sophistication and capabilities of UV water disinfection technology have grown exponentially. While manufacturers offer endless options for UV water disinfection systems, they can all be grouped into two main categories:

  1. Light-in-a-pipe systems. In these systems, pressurized water is exposed to 254nm UV light as it flows through a quartz tube. Light-in-a-pipe systems are advantageous in that they offer greater control over water conditions within the system, like preventing exposure to airborne pathogens. However, they can be costlier to operate given increased energy requirements and maintenance costs.
  2. Channel systems. In these systems, non-pressurized water is exposed to 254 nm UV light as it flows through an open channel. Channel systems are often used to disinfect large water streams, especially wastewater streams, as they can offer lower operation and maintenance costs. However, channel systems are also more vulnerable to airborne pathogens due to their open nature.

As both types of systems have advantages and disadvantages, it’s important for engineers to understand their options to find the best fit for their project.

uv-water-disinfection-benefits

Making water safer with better UV technology

UV systems are already a safe and reliable solution for disinfecting potable water, wastewater, reuse water, and rainwater, only becoming better with continual advances in technology.

Here are a few of the ways in which UV water disinfection technology is becoming smarter and more effective:

  • UV dose consistency. Maintaining a consistent UV dose ensures the water flowing through a UV system meets the minimum requirements for safe disinfection. Advances in lamp technology allow lamps to be calibrated at a higher intensity initially to maintain the minimum required intensity until the end of their lifespan.
  • Real-time monitoring. UV systems typically have sensors to indicate when performance falls below minimum thresholds. However, when sensors are poorly calibrated or the cause of an alarm is not clear, it can be a nuisance. Fortunately, smarter sensors and remote real-time monitoring are continually improving reliability while reducing maintenance requirements.
  • 360-degree coverage. Suspended and dissolved solids in water can cause shadowing within a UV disinfection system allowing pathogens to pass through. This challenge is being overcome with smarter system design, such as using dual lamps and reflectors to provide 360-degree UV light coverage that attacks pathogens from all angles.

With some countries actively shifting away from chemical disinfection, due to health and safety concerns, demand for UV water disinfection is growing. Understanding UV water disinfection is becoming increasingly important for engineers around the world.

Five considerations for upgrading an existing UV Pure system

Over 18,000 UV Pure systems are operating worldwide – with many providing years or even decades of reliable disinfection performance in potable, wastewater, and reuse applications. Over time, requirements for some sites can change, leading operators to evaluate different disinfection options to cope with higher flow requirements, changing water quality, emerging pathogenic threats or other factors.

The introduction of UV Pure’s new Hallett product line addresses these upgrade challenges with new technology, higher-capacity flow rates, and lower power consumption while continuing to provide the low-maintenance, highly reliable performance that operators trust from UV Pure.

As the UV Pure team prepares to ship the first of these new Hallett systems in early 2019, we share some answers below to common questions about the new units.

How are the new Hallett units similar to UV Pure’s proven Hallett 15xs and Hallett 30 systems?

The new Hallett units are still powered by UV Pure’s patented Crossfire Technology™, which includes automatic self-cleaning wipers, smart sensors, and built-in purging to prevent fouling of the quartz sleeve by mineral scaling and biofilm. This makes Hallett systems up to 10 times more effective in difficult water applications than conventional UV systems.

How are the new Hallett systems different from existing Hallett units?

The new Hallett units have been completely redesigned with better features and operability. The new systems 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 units are connected to achieve flow up to 1 MGD (3,785 m3/day).

What happened to UV Pure’s Upstream products?

Upstream systems will be discontinued in early 2019, but UV Pure will continue to offer replacement parts and full product support for years to come. New Hallett NC systems will replace Upstream models for disinfection applications that do not require product certification or validation.

How does UV Pure ensure its systems provide the appropriate level of public health and environmental protection?

UV Pure is offering a new Hallett system that is validated to the US Environmental Protection Agency’s (EPA) UV Disinfection Guidance Manual (UVDGM) protocols, as well as to the National Water Reuse Institute’s (NWRI) UV Disinfection Guidelines for Drinking Water and Water Reuse.

What type of warranty is available for replacement lamps?

UV Pure continues to offer a 12-month limited warranty for LPHO lamps, while amalgam lamps in the new Hallett 1000 model will be covered for 16 months.

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.

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.

How UV Pure added to the success of 2018 Solar Decathlon participant

Sole Canadian team in Chinese sustainable house competition adds UV Pure system to provide safe water.

A team of students, known as Team MTL, from McGill University and Concordia University recently participated in the 2018 Solar Decathlon, a competition that challenged participants to build a sustainable house using cutting-edge technologies.

The group, known as Team MTL, designed a house that uses a point-of-entry (POE) treatment UV disinfection system to treat the main water supply and protect residents from waterborne pathogens.

To ensure that they would never have to worry about water quality, the students wanted a UV disinfection system that provides a high level of safety for the water that is supplied throughout the house.

UV Pure donated a Upstream NC 15-50 disinfection system to support the experiential learning opportunities provided by the competition and improve the water quality of the main water supply.

The Upstream NC 15-50 system incorporates dual smart UV sensors that continually monitor UV lamp output and water quality, ensuring the highest level of treatment and public health protection. If either of these parameters does not meet the set specifications, the system will sound an alarm, notify the unit owner, and automatically shut down.

 

“We are grateful to UV Pure for supplying us with an Upstream NC 15-50 system for our home,” says Ben Wareing, Architecture Lead of Team MTL. “The system consistently provides a clean water supply to the house, ensuring the wellbeing of the inhabitants.”

 

Once treated with UV Pure’s disinfection system, the water is supplied to low-flow plumbing fixtures and appliances throughout the house such as the dishwater and washing machine.

This approach supports Team MTL’s water management strategy, which prioritizes conservation and reuse to help homeowners reduce potable water demand.

The 2018 Solar Decathlon took place in Dezhou, China from August 2 to August 19. A total of 48 universities from 10 countries around the world were represented in the 20 teams that competed in the Solar Decathlon.

At the end of the competition, teams were ranked in a number of categories, including: innovation, engineering, architecture, market appeal and communications.

Congratulations to Team MTL for placing first in the architecture, market appeal and communications competitions, and  third in the innovation and engineering competitions!

Team MTL
