Based in London, Ontario, Trojan Technologies produces open channel and pressurised UV disinfection systems for industrial applications, municipal water and wastewater treatment, commercial integration, residential use, and elimination of environmental contaminants from wells and other sources of drinking water (including reused water).
The company’s innovations in low-energy lamp design and optimised reactor performance have established benchmarks for the field that have fostered global adoption of UV technology. With installed systems at more than 5,800 facilities in more than 80 countries, Trojan has led the worldwide drive for commercial, engineering and regulatory acceptance of the technology as an environmentally sound alternative to traditional chlorine-based water treatment.
“Trojan’s success has contributed to a viable competitive industry in the area of ultraviolet technologies, leading to the development of a full range of industrial technologies in specialised and general applications,” noted the Stockholm Industry Water Award nominating committee in its citation.
“Their work with other members of the UV industry has advanced worldwide regulatory acceptance, overcome many limitations of existing technologies, and provided a new means of protecting public health and developing new sources of water supply.”
Executives from Trojan Technologies will formally receive the Stockholm Industry Water Award at a ceremony during World Water Week in Stockholm this coming August.
By demonstrating and communicating the benefits of UV-based water treatment solutions to government regulators and industry bodies, and using education to alleviate public concerns over the treatment and reuse of wastewater, Trojan Technologies has led adoption of the technology around the world. With water supplies at risk from overuse and contamination in the developing and industrial regions of the planet, decision makers now increasingly select UV technology to ensure the safety of drinking water.
Ultraviolet light purifies water by destroying the ability of microorganisms to function and reproduce. In water treatment applications such as those pioneered by Trojan Technologies, specialised lamps project intense UV light into the water, effectively neutralising the organic contaminants it contains.
UV water treatment systems are especially effective at eliminating disease-causing agents in wastewater. They destroy bacteria such as E. coli, viruses such as those causing hepatitis and polio, and virtually all water-borne pathogens, including chlorine-resistant types such as giardia and cryptosporidium. They also eliminate many micro-pollutants from herbicides and pesticides, a significant issue in agricultural regions.
UV technology also works more than 20 times faster than traditional chlorine-based systems, with no environmental impact from chemical leaks or any known disinfection by-products that could be harmful to health.
By virtue of these combined advantages, UV treatment presents an especially effective solution to the interrelated challenges of water quality and sufficient supply in arid regions. Its proven performance in eliminating all contaminants has led to public acceptance and confidence in sophisticated new applications for wastewater reuse.
In its citation, the Stockholm Industry Water Award nominating committee highlighted several recent installations of Trojan systems that illustrate the potential of UV treatment for wastewater reuse applications. The most notable of these are large-scale projects in Orange County, California and southeast Queensland, Australia.
