Modelling and Experimental Validation of the Interaction of Multiple Mercury Arc Lamps in Ultraviolet (UV) Reactors

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 more accurate model, which accounts for these phenomena, to better predict the distribution of UV light inside a reactor. To do this, we have developed a numerical model of the photon-plasma interactions, which agrees well with work found in the literature.

Accelerate development of new technologies and applications for advanced water treatment - Year two

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 one location to another by the discharge of ballast water.

Technical and Economic Assessment of Implementing UV Treatment in Potable Reuse Process Trains

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), and ultraviolet (UV) as treatment stages.

Development of rapid and accurate genomic techniques for ballast water UV treatment - Year two

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 mandated in the USCG protocol do not detect UV damage. Alternative culture-based measures of cellular replication capacity are yet to be approved, time consuming, and have limitations (some species mayn't grow).

Advanced Oxidation of Micropollutants in Water for Water Reuse

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) directly linked to societal nutrient management practices are of serious consequence for managing water resources.
