Communities on Long Island in New York State rely on extracting groundwater for most of their drinking water supply. After monitoring by the USEPA, it was determined that approximately 70% of wells extracting groundwater for public supply contained 1,4-dioxane - a probable human carcinogen - above the designated limits. Our Advanced Oxidation Process (AOP) solutions, the TrojanUVFlex® and TrojanUVPhox®, are installed at multiple well sites across the Island to remove 1,4-dioxane, helping to ensure the community has safe drinking water.
In 2019, Pall Water became a business of Trojan Technologies, bringing with them years of industry-leading experience in delivering membrane-based water treatment systems,

The Terrence J. O’Brien Water Reclamation Plant in Illinois serves over a million people and was the first among the top 10 largest wastewater plants in the U.S. to implement UV disinfection. The TrojanUVSigna® installed at this large plant disinfects a peak flow of 535 million gallons (2,025 million liters) of wastewater each day.
The TrojanUVSigna – a revolutionary advancement in wastewater disinfection – was introduced in 2010. It incorporates many innovations, including TrojanUV Solo Lamp Technology, that reduce the total cost of ownership for disinfection and drastically simplify operation and maintenance.
In 2011, the 9/11 Memorial opened to honor victims and provide a space for healing for their families.

It all began in 1977, when a young entrepreneur named Hank Vander Laan and his partner bought Trojan Metal Products Limited – a small company located in London, Ontario, Canada. The larger vision of what Trojan Technologies would eventually become was in the patent rights in this purchase; a small UV treatment unit for homeowners to use to purify their drinking water. These humble beginnings are the foundation on which we have built our vision to be a custodian of global water by engineering low-risk, innovative water technologies to ensure everyone has access to clean water.
