Emerging contaminants in drinking water are coming under increasing scrutiny as hazards to human and aquatic health. These compounds include pharmaceuticals, industrial chemicals, Endocrine Disrupting Compounds, and others. At present, the technologies for treating these compounds are costly and inefficient. Photocatalysis has been identified as a promising technique for treating these emerging contaminants in […]

Ultraviolet (UV) photoreactors for water treatment comprise UV lamps encased in quartz sleeves, immersed in the water to be treated. Over time, these quartz sleeves become fouled with materials from the water, reducing the amount of UV available for treatment. This phenomenon requires that the systems be over-sized and often include costly automatic cleaning systems […]

Conventional wastewater treatment process includes primary treatment (clarifier), secondary treatment (aeration tanks) and anaerobic digestion (AD) of primary sludge (PS) and waste activated sludge (WAS), followed by disposal of the bio-solids from of the AD process. It is estimated that the sludge treatmen/disposal processes account for approximately 40% of the costs for a wastewater treatment […]

Demand for water and wastewater treatment has grown substantially in recent years, leading to a increased need for innovative technology. To remain a global leader in UV-based treatment technology, Trojan must continue to innovate through its intesive research and development program. One of Trojan’s distinguishing features has been the rigorous analysis and testing that our […]

Global population growth, urbanization and changing climate patterns have increased the demand for potable water, wastewater reuse and value recovery from wastewater, and treatment of industrial process water. Population growth also results in increased demand for the shipping of goods by ocean freight, with the associated risk of the transport of unwanted marine life from […]

Driven by climate change induced water scarcity, further enhanced by rapid urbanization and population growth, potable water reuse initiatives are gaining interest. Potable reuse involves the indirect or direct use of highly treated municipal wastewater as a municipal drinking water source. Historically, the most commonly installed potable reuse train consisted of microfiltration, reverse osmosis (RO), […]

Trojan Technologies uses ultraviolet (UV) lamps in reactors to purify water. When multiple lamps in a reactor are active at once, light emitted by the various lamps can interact with neighbouring lamps, creating effects that are not well taken into account in current industrial lamp models. The goal of this project is to develop a […]

Trace concentrations of numerous organic compounds (emerging contaminants (EC), and endocrine disruptor compounds (EDCs)) such as pharmaceuticals and personal care products (PPCP), including prescription drugs and biologics, “nutraceuticals,” fragrances, sun-screen agents, and numerous others are reported in various wastewater effluents, and aquatic systems. In addition to these, increasing levels of naturally occurring organic materials (NOM) […]

The United States Coast Guard (USCG) recently introduced stringent regulations for the treatment of ballast water. Ultra-violet (UV) light is a useful technology in a ballast water treatment system (BWTS), for inactivating species which could be invasive and harmful to humans and the environment. UV damages DNA and prevents replication, but the vital stain methods […]
