The Solo Lamp™ is the most powerful, high-efficiency lamp in the world and is paired with the advanced, energy-efficient Solo Lamp™ Driver. It is no longer necessary for municipalities installing UV technology to make a choice between energy-efficiency and a small footprint. This revolutionary lamp technology offers the high electrical efficiency of a low-pressure UV system, while simultaneously providing the low lamp count similar to a medium-pressure UV lamp system.

“Our customers’ needs are evolving, and so too is our UV technology,” says Marvin DeVries, President of Trojan Technologies. “Thanks to technology advancements like this, our future water treatment systems can be designed to provide both high UV output and high electrical efficiency – the best of both worlds. After five years of research and development, we are excited to officially launch TrojanUV Solo Lamp™ Technology, and are looking forward to introducing it at ACE’10.”

By using fewer and more efficient lamps, the carbon footprint associated with UV treatment is reduced to less than 1/3 that of medium pressure UV lamp systems. The increased efficiency of the Solo Lamp™ translates into a significant reduction in wasted energy, peak electrical loads, and associated electrical infrastructure.

“Our Solo Lamp™ Technology will be offered for drinking water, wastewater and environmental contaminant treatment, and will form a key technology platform for future large-scale applications,” says DeVries.

The TrojanUV Solo Lamp™ and Driver Technology enables the design of an extremely energy-efficient solution with the smallest physical footprint and total lamp count possible. The result is a low-maintenance system coupled with ActiClean™ – an effective, dual action lamp sleeve cleaning system – to maximize total efficiency and minimize power consumption.

The $1.4 billion (€0.9 billion) plant, located in Westchester County, New York, will treat an average of 1.3 billion gallons (4.921Mm3) of water daily from the Catskill and Delaware reservoir systems, which supply most of the city’s daily water demand. It will have the overall capacity to treat more than two billion gallons a day – all of the city’s drinking water needs even during peak demand times.

The NYCDEP awarded the contract to construct the facility to the joint venture of Skanska USA Civil (White Plains, New York), ECCO III (Yonkers, New York), and J.F.White (Framingham, Massachusetts). A joint venture of Malcolm Pirnie (White Plains, New York) and CH2MHill (Englewood, Colorado) is serving as the construction management team. The project designer is a joint venture of Hazen and Sawyer (New York, New York) and CDM (Cambridge, Massachusetts).Trojan Technologies, London, Ontario, Canada, is supplying the UV technology.

Paul Whitener, CH2MHill’s project manager, says the project is slightly ahead of schedule, with all major excavation complete, and concrete foundations and all structural steel scheduled for the next couple of months.

‘This is a landmark facility within the drinking water industry,’ he adds. ‘We are proud to be partnering with Malcolm Pirnie and the NYC Department of Environmental Protection to provide high-quality drinking water to the DEP’s nine million customers.’

New York City provides its eight million residents and one million upstate customers with high quality drinking water drawn from the largest unfiltered surface water supply in the world. Since the mid-1800s, when local well water sources became polluted as the city’s population grew, New York has transported drinking water from reservoir systems located as far as 100 miles (160km) north of it. Most of the water moves by gravity through pipes and aqueducts, saving significantly on energy requirements for pumping. Total storage capacity in the reservoir systems is 580 billion gallons (2195Mm3).The Catskill reservoir system, developed in the early 1900s, and the Delaware reservoir system, built in stages between 1930 and 1970, meet most of the city’s demand.

Several interconnections among the three water systems increase flexibility by permitting exchange of water from one to another, buffering the effect of localized droughts and capitalizing on excess water in any of the three watersheds.

The 1996 amendments to the United States Safe Drinking Water Act now require that all drinking water drawn from surface water supplies must be filtered unless the government grants a waiver (known as a Filtration Avoidance Determination, or FAD).To satisfy the requirements of such a waiver, the NYCDEP agreed to build the UV disinfection plant, supplementing the existing chlorination disinfection facilities for the Catskill and Delaware supplies. According to construction estimates, a filtration plant would have been much more expensive.

The new UV system is designed to achieve up to 99.9 percent (3-log) inactivation of cryptosporidium to meet the future requirements for unfiltered water. The system consists of 56 UV units each sized to handle 40 million gallons a day, making them some of the largest ever built.

As reported in a paper at the American Water Works Association annual conference in 2006, project designers and the city evaluated both medium pressure and low pressure-high output UV lamp systems for an extensive range of factors, including staffing requirements, power consumption, and maintenance. In the end, the low pressure / high output units were selected based on 30-year life cycle (present worth) costing.

The UV units consist of stainless steel disinfection chambers containing an array of UV lamps inside quartz sleeves that are immersed in the water flow. UV light alters the DNA of water based microbes, such as giardia and cryptosporidium, and prevents them from replicating.

Trojan was selected after a rigorous validation process which included Trojan building one full-size UV unit designed for the project, which underwent performance tests at an independent test facility in Johnstown, New York.

According to Jennifer Muller, municipal UV market director for Trojan Technologies, her company has supplied some of the largest UV-based treatment units in the world for wastewater disinfection, drinking water disinfection as well as UV-oxidation for environmental contaminant treatment (Madrid, Milan, Rotterdam, Honolulu and Atlanta among them).But the New York facility is the largest in the US in terms of flow capacity treated as well as the number of UV lamps. Still, design concepts and components are similar to conventionally-sized projects, she says.

‘The physical size and weight of each individual UV unit was larger than any we’ve had to work with previously, but didn't pose any significant challenges,’ she says. ‘Each unit includes an access hatch sized such that a person can actually climb into the UV unit (for maintenance) and would likely discover that it’s larger than some apartments in New York City.’

‘New York has taken a big step toward ensuring the continued quality of its citizens’ water supply and protecting them from the many diseases that can be caused by water-borne pathogens,’ said Marvin DeVries, Trojan’s President. ‘This facility will triple the UV capacity in the United Sates.’

The NYCDEP’s Roman said the new facility is being funded out of the department’s capital projects budget. He said the project would not provide any additional water supply to New York City, but would assure advanced treatment of the existing supply.

Abstract & Chapter Summaries:

This is the second guidebook on commercial membrane technology written by a team of membrane technology professionals and published by Balaban Desalination Publications. The material included in the first guidebook (published in 2007) covers mainly brackish and seawater desalination technology and applications. This guidebook is dedicated to the membrane technologies applied in wastewater reclamation processes. The reasons for a separate book on wastewater reclamation technology are related to the unique treatment challenges, potential of sufficient availability and affordable economics of utilizing this water source: The water sources, used for wastewater reclamation, are highly contaminated with constituents that embody conditions of environmental and health concern. Therefore, specialized and highly reliable treatment technologies are required for applications that involve water reuse; Wastewater is available in abundant quantities at locations that allow convenient conveyance to the treatment facilities and distribution of treated effluent to potential users; Energy requirement of the treatment process is low compared to other alternatives of augmentation of water supply; Advances in membrane technology for wastewater reclamation contributed to its increasing recognition as a reliable technology for cost effective production of high quality effluents.

The objective of this book is to describe commercial treatment technologies and explain in simple engineering terms modern membrane applications in wastewater reclamation processes. Examples of design and process calculations and case studies are provided to illustrate methods of system design, calculation of process parameters and evaluation of process economics.

The book content was formulated to serve as a reference for configuration and design processes of membrane systems in wastewater reclamation and reuse applications for project engineers, plant designers, planners, utility directors and operations managers, involved in municipal and industrial reclamation projects. It is also anticipated that the book will provide information on practical approaches of these technologies and processes to scientists and academics interested in commercial wastewater reclamation applications.

Water scarcity is set to dominate the sustainability agenda in the 21st century. Population growth, climate change and increasing demand for water mean we have to do more with less. Urban areas are especially vulnerable and recent trends in rainwater harvesting and water reuse will become mainstream. As municipalities face the pressing issue of water scarcity, Trojan Technologies has led the way providing solutions using environmentally responsible, cost-effective ultraviolet (UV) light for water recycling and disinfection applications.

Water sources we rely upon every day are becoming increasingly impacted by natural and man-made contaminants such as pesticides, fuel additives, volatile organic compounds and nitrosamines. UV light alone, or in conjunction with hydrogen peroxide, can safely destroy these biological chemical contaminants in water, helping to restore its natural condition and making the water safe for reuse or for release back to the environment.

Wastewater treatment plants have traditionally used chlorine gas or liquid bleach to disinfect treated sewage before discharge into rivers and streams. Chlorine, while an effective disinfectant, is a toxic, hazardous chemical that can be deadly in the event of a leak or spill. The chlorination process can also create carcinogenic byproducts harmful to the environment and aquatic life. Today, large US cities including Atlanta, Birmingham, Honolulu, and Las Vegas have adopted environmentally friendly Trojan UV disinfection for their wastewater treatment plants.

Climate change, growing populations and the resulting water stress are driving forces for wastewater reuse in arid states such as Florida, Arizona and California. A water reuse plan that augments fresh water supplies, either directly or indirectly, is a viable option for municipalities of any size or location. Recycled and disinfected water is commonly used for irrigation of golf courses, landscapes and commercial properties. Demands on the city’s drinking water supplies are also reduced when recycled water is used for cooling, firewater, service and other processes.

The Orange County Groundwater Replenishment System in California is the world’s largest Indirect Potable Reuse (IPR) system – capable of recycling 100 million gallons of wastewater per day. The finished water, treated with a TrojanUVPhox UV-oxidation system, is used to recharge groundwater aquifers and prevent seawater intrusion. The Orange County facility is an award-winning example of how advanced treatment can cost-effectively convert wastewater back to a quality that exceeds drinking water standards. Some insist on calling it ‘toilet to tap’ – I call it socially responsible engineering in challenging times.

The City of Palo Alto, California conducted a detailed carbon footprint analysis concluding that chlorine disinfection has a larger carbon footprint due to transportation of chemicals to the treatment plant. Similarly, Trojan Technologies performed a Life Cycle Assessment on various disinfection processes to determine the overall environmental impact of UV and chlorine. It was shown that UV had the least environmental impact in all categories (e.g. global warming potential, human health effects, ecotoxicity, ozone depletion, etc.). As sources of electricity become more renewable, UV’s overall impact on the environment will continue to decrease.

Reuse of wastewater, now recognized as an ecological and economic necessity, is increasingly practiced not only in the United States, but globally in water scarce regions such as Australia, Spain and Italy. For over two decades ultraviolet radiation has been successfully used to disinfect reuse water in a cost-effective manner. UV is a non-chemical disinfection technology that protects the public against pathogenic micro-organisms including protozoa, bacteria and viruses. In comparison to chemical disinfection, UV does not produce harmful by-products, is non-toxic to the environment and has the lowest environmental impact making it truly a ‘green’ solution.

>>Article [PDF] http://trojanuv.com/about/news?id=263 Thu, 18 Mar 2010 12:00:00 EDT The water and wastewater sector experienced rapid growth in 2008 fuelled by huge investments in infrastructure, but the global economic crisis is now expected to restrain market growth. What impact has the crisis had on the sector in your opinion?

David Tomowich: As we all know, water is vital to survival and therefore proper treatment of water, including disinfection, is key to maintaining a healthy community, environment and economy. The global economic crisis has been felt within the industry on a project level as some projects have been delayed or even cancelled due to funding re-prioritisation or lack of residential development and construction. Having said that, the water industry overall continues to grow since water is such a vital resource. Even during tough economic times there is usually a focus on infrastructure that includes developing the supply of safe reliable water treatment.

What are the biggest challenges facing the water industry in the Middle East? How is your solution best placed to tackle these challenges?

David Tomowich: The Middle East is experiencing unprecedented growth that will naturally put a lot of strain on the existing infrastructure in place to treat water. A big challenge may be the planning as well as having resources in place to keep up with the growth and demand for water and wastewater treatment – especially considering the water shortages already experienced in most middle-eastern countries. Another challenge for the Middle East will be to put in place and enforce regulations that ensure minimum water treatment standards are being met during this period of rapid growth and beyond. Trojan’s UV disinfection solutions have played an integral part in hundreds of reuse and water recycling plans worldwide. UV can easily be installed into existing wastewater or drinking water plants to increase levels of public health protection. In terms of meeting sustainability objectives, UV offers a safe chemical-free approach to disinfection with an environmental footprint significantly lower than alternative disinfectants or desalination.

Governments in GCC countries have identified municipal wastewater treatment as the priority area for multiple reasons including the achievement of the Millennium Development Goals. Where do you see the main growth opportunities in the water and wastewater sector and what are you doing in this area?

David Tomowich: In the drinking water sector, Trojan is designing and providing ultraviolet systems that protect the public against potentially harmful protozoa, bacteria and viruses. To date, these drinking water installations tend to be on a smaller scale. We are encouraging the adoption of UV disinfection technology by larger facilities – the benefits to the cities and communities are significant. Regulations, installations and experience is available globally and can be drawn upon as needed in the Middle East. UV disinfection has played a key role in the Middle East for over a decade and will continue to be a growth market. The demand for reliable technology and the use of best design practices needs to be a priority of regulatory agencies, consultants, the end-user and equipment suppliers alike. Meeting the demands of growing populations and addressing water scarcity will only be successful if new standards of treatment are formulated and adopted into future water treatment plans.

A recent Frost and Sullivan report concludes that the water and wastewater market is set to grow to US$1.87 billion by 2013. What are your thoughts on the water and wastewater industry in the MENA region over the coming three years? What do you expect to see happen and what do you hope for the sector?

David Tomowich: We expect to see significant project-related activity including UV applications and significant growth and advancement in the field of water treatment – especially as the economy rebounds and delayed projects move forward. We need to ensure there is proper design, validation and application of technologies in any rapidly growing market to ensure a successful outcome. Industry leaders, regulators, consultants and end-users all need to play a role to ensure objectives are established and met. I expect to see rapid growth in the water and wastewater treatment sectors in the coming years. My hope is that we see additional emphasis on inherently greener technologies and that industry participants take an active role in the development and implementation of critical planning projects, policies and regulations that address water scarcity in the region.

The ultraviolet light system would be installed on ships, purifying the ballast water that is pumped off as the vessels take on cargo.

A new international treaty is aimed at cracking down on ships dumping ballast water that could contaminate fragile ecosystems.

"Lots of other companies are developing products for this market," said Trojan Technologies chief executive Marvin DeVries. "There are about 50,000 ships floating on the oceans today and unless they avoid international travel, they will be subject to these requirements."

Trojan is hoping to gain an edge by partnering with Wartsila, a Finnish company that supplies engines and other major components for freighters and cruise ships. Wartsila, with 160 locations in 70 countries, will sell and service Trojan's purification system to its customer base.

"We are strong on the technology side. We know how to treat dirty water, but we don't have a real presence in this (marine) market," said DeVries.

Ships pump in ballast water to keep them level as they unload cargo. The ballast water often is pumped out at another distant port.

The discharged ballast water can contain a wide variety of aquatic creatures and microorganisms that can overwhelm native species and cause other damage to the ecosystem.

Ballast water has been blamed for the introduction of invasive species such as zebra mussels into the Great Lakes.

DeVries said algae and micro-organisms also can cause serious environmental damage.

The Trojan device will use a combination of filters and screens to take out small marine species while ultraviolet light would eliminate the micro-organisms.

The system would work in combination with a ship's ballast pumps and the basic filtering systems that take out larger aquatic species.

Authorities in Canada and other nations are monitoring ballast water as ships enter port.

The International Maritime Organization is working on a treaty requiring all new ships to have a ballast water purification systems and existing ships to have a system installed by 2014.

DeVries said retrofitting in the engine room of older ships presents a challenge.

"Space is at a premium, so coming up with something very compact is key to the effort," said DeVries.

He said Trojan should have prototype for the purification system in the fall and be ready to put it on the market next year.

Wärtsilä and Trojan Technologies sign agreement to launch ballast water treatment product

Industry leaders introduce ultraviolet technology to marine market with ballast water treatment product

Wärtsilä Corporation and Trojan Technologies have signed an exclusive agreement to jointly develop, market, and distribute a ballast water treatment product for ships. The two companies will gain synergistic benefits from the combined strength of Wärtsilä’s global reach and presence in the marine market, and from Trojan Technologies’ leadership and experience in developing ultraviolet treatment solutions. The ballast water treatment product is presently in pre-production, with third-party validation to take place in late 2010. The innovative ballast water treatment product is expected to enter the market at the end of the year.

Changing regulations in the marine industry have driven the need for this new ballast water treatment product. In 2004, the International Maritime Organization (IMO) adopted the Global Ballast Water Convention, which mandated ballast water treatment. Ballast water is used to stabilize vessels when not fully loaded: water is taken in when a ship unloads cargo, and released when it is loaded again. Water that is taken in at one port is often released at another, which can result in the introduction of non-indigenous organisms into fragile ecosystems. Untreated ballast water has been an issue of serious public concern during recent years.

According to the Global Ballast Water Convention, all vessels built prior to 2009 will need to install a certified ballast water treatment (BWT) system by 2014 or 2016, depending on the ballast water capacity of the vessel. Since 2009, all new vessels are required to install a BWT system. For the convention to come into full force, it must be ratified by 30 countries representing 35 per cent of the global fleet’s dead weight tonnage. Currently 21 countries representing 23 per cent of the world’s dead weight tonnage have ratified, and full ratification is expected to occur in 2011.

“Ballast Water Treatment is becoming an important item on the environmental agenda for our customers, and therefore also for us,” says Roger Holm, Vice President, Solutions Management, Wärtsilä Services. “Moving into this field is a natural step for Wärtsilä, and one that continues the development of our Environmental Services portfolio.”

Trojan Technologies has over 30 years of experience in developing ultraviolet treatment solutions. As the world leaders in developing UV technology for municipal wastewater, drinking water, and industrial water treatment systems, Trojan Technologies was a logical partner in providing Wärtsilä with UV technology for ballast water treatment. Trojan Technologies has the experience, and the research and development capabilities to develop an energy-efficient, integrated, proprietary technology with a compact footprint and the flexibility to upgrade as regulations continue to evolve.

“Trojan is excited to partner with Wärtsilä in this endeavour,” says Marvin DeVries, President of Trojan Technologies. “Trojan has a long history of innovation and leadership in the global UV industry, and we believe that our water treatment expertise, combined with Wärtsilä’s strong presence in the marine industry, will enable the two companies to play a significant role in providing a compact, cost-effective and high performance system to address the emerging ballast water treatment market.”
