Initial Expansion Project

The Lowest Lamp Count, Lowest Energy and Easiest-to-Maintain UV System for Drinking Water Disinfection

Today, TrojanUV launched the TrojanUVTelos™ (télōs), a UV system that sets a new standard for ultraviolet (UV) disinfection for small communities.

The system combines TrojanUV Solo Lamp™ Technology and the revolutionary TrojanUV Flow Integration (FIN™) Technology to deliver the lowest lamp count, lowest energy, and easiest-to-maintain UV disinfection system available. No compromises are needed with the compact and efficient TrojanUVTelos.

“In the world’s communities, providing safe drinking water without the overuse of chemicals and without creating disinfection by-products is a continual challenge,” says Marv DeVries, president of Trojan Technologies. “Our goal with TrojanUVTelos is to make UV disinfection easier and more cost effective.”

These cost savings are driven by FIN, a new hydraulic optimization technology developed by TrojanUV. FIN advances the science of mixing and light distribution inside a closed vessel UV system to never-before-achieved levels. Inside the TrojanUVTelos, FIN uses patent-pending flow modifiers distributed throughout the length of the UV chamber to ensure the highest possible UV disinfection performance, reducing lamp counts, energy requirements and overall operational costs. 

“Our customers correctly demand lower energy consumption and lower lamp count. We created the TrojanUVTelos to address the needs of the energy- and maintenance-conscious buyer,” states Adam Festger, Drinking Water Market Manager at TrojanUV.  “The Solo Lamp and UV system design advancements are allowing us to design higher efficiency and lower maintenance UV systems than ever before.”

Even in developed countries, water can act as a vehicle for illness. The USEPA reports that in the United States, tens of thousands of public water systems, the majority of which extract groundwater, provide water without disinfection. A recent report on European drinking water identified that approximately 12% of European drinking water is also not disinfected. The TrojanUVTelos is designed to simplify implementation of drinking water disinfection and protect communities from a wide range of pathogens including bacteria, viruses and chlorine-resistant protozoa such as Cryptosporidium and Giardia.

With TrojanUVTelos, SCADA connection is standard, as is remote online monitoring and enhanced regulatory reporting capability. Drivers and controls are pre-assembled and mounted on the UV chamber which eliminates the need for a separate, wall- or stand-mounted cabinet. This greatly simplifies installation and reduces footprint. DVGW certification is in progress, will be completed in early 2015, and will equip the TrojanUVTelos to meet the latest drinking water disinfection regulations globally. 

Telos, or Τέλος, is a Greek word meaning an outcome or goal. With the TrojanUVTelos, we believe that we have achieved a significant milestone in drinking water disinfection.

The solution comes by treating water consisting of treated wastewater effluent and mixture of freshwater and saltwater.

This involves a three-step process: 

1. Removal of solids through filtration
2. Desalination using reverse osmosis
3. Disinfection and removal of remaining chemicals using the TrojanUVPhox™ solution with ultraviolet light and hydrogen peroxide

Under the most severe drought ranking issued by the National Drought Mitigation Center for the past three years, Cambria had invoked mandatory water conservation measures for its residents, including the prohibition of all outdoor water irrigation using potable water, limiting residential water use to no more than 50 gallons per person per day, and reducing commercial water use by 20%, all of which were accompanied by strict fines for non-compliance.

The CCSD implemented a strategy for an emergency water supply system, which became operational in January 2015, and is intended to get through challenging drought periods. The system is designed for the reuse of wastewater for augmentation of drinking water supplies, a process known as indirect potable reuse, and is a means of achieving a sustainable water supply and protection against drought.

While the plant is currently operating under an emergency permit, the CCSD is looking at making the system a permanent solution and believe it could also be a possibility for other communities experiencing similar issues.

The CCSD emergency water supply plant has been shortlisted for the Desalination Plant of the Year award by Global Water Awards 2015, which represents the most impressive technical or ecologically sustainable achievement in the industry. The winners will be announced on April 27, 2015 at a ceremony at the Nasioutzik Museum in Athens, Greece.

The Otter Lake Water Commission has installed our TrojanUVSwift™ECT – a technology which optimizes the treatment of environmental contaminants, particularly taste and odor-causing compounds found in surface waters. This is the first ECT installation and the first UV system to receive disinfection credits in the State of Illinois.

Built in 1969, the Otter Lake Water Commission treatment plant serves approximately 17,000 people in the towns of Auburn, Divernon, Girard, Pawnee, Thayer and Virden. The treatment plant has a maximum flow rate of 1.5 million gallons per day.

In 2006, concentrations of MIB, a contaminant responsible for taste and odor (T&O), exceeded 6,000 ng/L in water treated by the Otter Lake Water Commission. In 2010, an LT2 Bin classification of 2 was issued, requiring an additional 1-log Cryptosporidium inactivation.

To analyze these issues and develop a solution, the Otter Lake Water Commission conducted a series of studies. The analysis concluded that UV-oxidation was the most reliable option to obtain the required 1-log Cryptosporidium inactivation, while simultaneously delivering T&O treatment.

The plant passed performance testing in August 2014 and has successfully treated a T&O event. As of September 2014, the plant is capable of treating 1.7-log of MIB (2-methylisoborneol) and algal toxins, including year round disinfection (2-log Cryptosporidium inactivation.) 

The Six Nations of the Grand River has opened its new water treatment plant, which features the TrojanUVSwift™ECT system. This system is treating water drawn from the Grand River, which receives the water of several municipal wastewater plants upstream of this plant’s water intake.

The raw water is challenging to treat and utilizes membrane filtration and a TrojanUVSwift™ECT system to destroy contaminants such as pesticides and taste and odor-causing compounds while providing disinfection of chlorine-resistant protozoa.

The water treatment plant opened in January 2014 and is capable of supporting up to 7,370 users. Treating water for N-Nitrosodimethylamine (NDMA) and taste and odor (T&O), it has a production capacity of 50 L/s, which is almost four times that of the old plant.
The Six Nations reserve is located in Ontario and is bordered by the County of Brant, city of Brantford, Norfolk County, Haldimand County,and has a subsection reservation, the New Credit Reserve located within it boundaries.

Discussions took place between Six Nations council and the Government of Canada for more than a decade about building a new water treatment plant to replace the old infrastructure that was becoming gradually obsolete. Six Nations council also wanted a system that could eventually serve all households and commercial development in Tuscarora Township.

The Government of Canada provided $26 million toward the funding of the project through Canada’s Economic Action Plan as part of an overall plan to invest $189 million on water and wastewater projects in Canada.

In May 2014, Wichita Falls, Texas found itself under a stage 5 drought catastrophe ranking during the second worst drought in the city’s history. The lakes supplying water to the city were at less than 25% capacity, resulting in restrictions on outside irrigation and residents and businesses were encouraged to conserve water as much as possible. Despite reducing water supply by one-third, water was still expected to run out within two years under the drought conditions.

Wichita Falls city officials developed a short-term solution to the problem – to treat and purify wastewater so it could be reintroduced into the potable water supply. The city built a 13-mile pipeline from the wastewater treatment plant to the drinking water plant, installed advanced treatment equipment including membranes and reverses osmosis, and began extensive testing by the Texas Commission on Environmental Quality (TCEQ) to ensure the water was meeting treatment goals. The project went online in July 2014 under a temporary emergency permit serving a population of just over 100,000 using a 50-50 blend of treated wastewater and lake water.

As the temporary emergency permit timeline came to an end, the city requested an extension on the project. In order for the Direct Potable Reuse (DPR) project to be extended, the Texas Commission on Environmental Quality required the installation of a UV-treatment process to act as an additional barrier for Cryptosporidium inactivation. All other DPR projects that have been approved in Texas have included UV as part of the treatment process. 

Trojan Technologies delivered the TrojanUVSwift™ECT to Wichita Falls in late December 2014 in order to support the city and its DPR project, which was at risk of being forced offline by TCEQ unless an additional UV disinfection barrier was installed. By February of 2015, Wichita Falls had commissioned the TrojanUVSwift™ECT, allowing the city to receive a one-year extension on its DPR project, versus a six-month extension without UV treatment.

Along with a similar project in Big Spring, Texas, Wichita Falls is Trojan’s second UV installation and the state’s second site for DPR. The project has received global attention as representatives from several countries have visited the city’s treatment plant to learn more about the technology that makes DPR a viable treatment option for wastewater reuse. 

About the TrojanUVSwift™ECT

Its ultra-compact footprint, its ability to apply large amounts of UV light, and high flow capacity make the TrojanUVSwift™ECT an excellent reactor for use as part of a multi-barrier system in large municipal applications. In such an application, the TrojanUVSwift™ECT can destroy contaminants such as pharmaceuticals and taste and odor-causing compounds while providing disinfection of chlorine-resistant protozoa.

At ACE 2015, our Market Manager Adam Festger sat down with Water Online to discuss drinking water solutions for small communities, TrojanUVTelos, TrojanUVSigna and more.

When it comes to community drinking water systems, most are classified as small or very small (in the U.S.), serving less than 3,300 people. Though the volume of people served pales in comparison to large systems, that’s still a lot of plants to operate. As regulations tighten and the need for better treatment technologies arises, the implementation of new tech into small plants with few operators becomes a concern.

TrojanUVTelos was developed for precisely this reason. In the interview, Adam Festger explains the technology that goes into the TrojanUVTelos system, particularly the implementation and advantages of the low-pressure TrojanUV Solo Lamp.

Tucson Water’s Advanced Oxidation Process (AOP) Water Treatment Facility was awarded the 2015 Grand Prize in Design from the American Academy of Environmental Engineers and Scientists (AAEES).

As part of a commitment to provide safe, reliable drinking water, the city of Tucson, Arizona completed the installation of a new Advanced Oxidation Process Water Treatment Facility in January, 2014. The system uses 6 TrojanUVPhox units and supplies purified water to nearly 50,000 people.

The technology is treating groundwater contaminated with 1,4-dioxane and other volatile organic compounds (VOCs ), which were used in aircraft manufacturing companies in the Tucson airport area from the 1940s to 1970s.

1,4-dioxane is a contaminant not easily removed with conventional technologies, but TrojanUV’s oxidation systems destroy VOCs, breaking them down into their harmless components almost instantly. The process combines ultraviolet light with hydrogen peroxide to purify up to 8 million gallons of water a day.

The AAEES Award celebrates the best in environmental projects and programs. The Academy states that the complexity of the design, integration and implementation of the project was “unprecedented in Arizona” and that:

The new AOP facility restores the Tucson Airport Remediation Project (TARP) facilities to full effectiveness without compromising water quality commitments or requiring additional water supplies for blending.”

The ribbon has been cut at the Terrence J. O’Brien Water Reclamation Plant (WRP) in Skokie, Illinois. The TrojanUVSigna™ is now online and able to disinfect a peak flow of 525 million gallons of wastewater per day. The plant serves more than 1.3 million people within 143 square miles and was the first among the top 10 largest wastewater plants in the U.S. to implement UV disinfection.

TrojanUVSigna at the Terrence J. O'Brien Reclamation Plant

The Metropolitan Water Reclamation District of Greater Chicago (MWRD) – of which the Terrence J. O’Brien WRP is part of – has made a number of upgrades to its treatment process in recent years. The addition of UV disinfection has been a critical part of these upgrades; it plays a key role in improving water quality throughout the Chicago Area Waterway System (CAWS), and helps to protect the region’s drinking water supply in Lake Michigan.

A Need for Innovation

Industry-leading Technology

The TrojanUVSigna™ was introduced in 2010. It was the industry's first large-scale wastewater disinfection system to utilize high-powered, high-efficiency amalgam lamps (TrojanUV Solo Lamp™ Technology) positioned in a staggered, inclined array.

Municipalities around the world are installing the TrojanUVSigna™ for several reasons. For the MWRD, those reasons included simplified maintenance, demonstrated disinfection performance, and UV’s environmental benefits. We are proud that our technology is helping them protect and safeguard their waterways.

The ribbon-cutting ceremonies took place on March 23, 2016.
