AGENDA Introduction Core Business UV Basics and Advantages Capabilities Questions
TROJAN FOUNDING PRINCIPLE Trojan is uniquely positioned to bring innovative, technology-based solutions to municipalities, industrial enterprises, and consumers to solve their water related and process problems in an environmentally responsible way.
TROJAN TODAY A Global Environmental Business with staff of 650 Canada London & Guelph (400) US Multiple locations (175) Europe Multiple locations (50) China Multiple locations (25) • • Over 6,000 municipal UV installations on 6 continents,treating over 26 billion gallons/day, 4M m³/hr •UV for municipal, industrial, commercial and consumer applications • Environmental Contamination Treatment UV-H2O2 for removal of micro-pollutants, odour and corrosion control • Partnerships: Over 200 offices in 90 countries on 6 continents • Logistics & Manufacturing in Canada, US, Europe and China • Sales in 2009: US$ 220 M.
TROJAN UV COMPANY OVERVIEW • Over 30 years of UV water treatment experience • 650+ employees worldwide • Annual turnover of US$220M in 2009 • Thousands of UV installations in 6 continents • Worldwide sales & support • UV pioneers with dedicated R&D resources • ISO 9001 Certified, CE, DVGW, UL, CSA, NSF • Business unit of the Danaher Corporation (DHR)
DISINFECTION WATERBORNE MICROORGANISMS Microorganisms in drinking and waste water represent a risk to Public Health. Bacteria Viruses Protozoa (E.coli) (Hepatitis, Polio) (Giardia) (Cryptosporidium)
Cell Wall DNA Nucleic Acid Cytoplasmic Membrane UV DISINFECTION HOW DOES IT WORK? UV light at the 254 nm wavelength penetrates the cell wall of the microorganism. The microorganism is “inactivated” and rendered unable to reproduce or infect. UV Energy
Adenovirus Rotavirus Poliovirus Hepatitus A Legionella Streptococcus Crypto Giardia E.coli UV AS PART OF MULTI-BARRIER STRATEGY Typical Chlorine CT for Giardia Chlorine Disinfection UV Dose Typical Design UV dose = 40mJ/cm2 UV Disinfection Dual Protection Chlorine CT
WHY UV? ADVANTAGES • Effective against bacteria, viruses, and protozoan pathogens • No disinfection by-products formed • Not affected by pH, temperature • Easy maintenance and operation • Environmentally friendly technology • Economical alternative to other disinfection techs

ADVANTAGES OF UV DISINFECTION UV disinfection is a physical process No hazardous or toxic chemicals are used, eliminating public health concerns associated with THMs, HAAs or other carcinogenic by-products UV inactivates a broad spectrum of pathogens, including Giardia and Cryptosporidium Inactivation of chlorine-resistant parasites protect downstream recreational waters and surface waters used as a potable water source UV disinfection takes only seconds to inactivate organisms Since the contact times are short, the footprint required is minimal and existing chlorine contact tanks can be reused
ADVANTAGES OF UV DISINFECTION UV disinfection does not leave a residual disinfectant No de-chlorination or residual monitoring is required, which greatly reduces operation and maintenance costs Receiving waters are not negatively impacted and there is no risk of overdosing UV is an accepted, proven technology in thousands of installations around the world UV is easily designed by consulting engineers and approved by regulatory bodies, thereby reducing engineering costs and reducing permit approval time Upgradeable to UV oxidation or photolysis system Treatment process can be upgraded to treat emerging contaminants, offsetting upgrade costs in the future
Cell Wall DNA Nucleic Acid HOW DOES UV WORK? • UV light penetrates the cell wall • The UV energy permanently alters the DNA of the microorganism • Microorganisms are “inactivated” and unable to reproduce or infect UV Energy

DEFINITION OF UV DOSE UV Dose = Intensity x Retention Time (mWs/cm2) (mW/cm2) (seconds) • Higher dose means greater DNA damage and more bugs are killed • Different bugs require different doses to achieve same kills (e.g. bacteria vs. viruses)
UV Transmission Scale: 20% - 50% 50% - 70%> 70% • Post-membrane • High-level reuse • Contaminant destruction • Secondary Effluent • Filtered Effluent • WW Reuse • Fixed Film Effluent • Primary Effluent • Blended Effluent • Lagoons • CSO, SSO UV TRANSMITTANCE • The ability of light to transmit through water • The ratio of light entering the water to that exiting the water • Sample length of 1 cm
Scatter UV Light UV Lamp Complete Penetration Incomplete Penetration limits DNA damage THE EFFECTS OF PARTICLES Shade Particles
QUARTZ SLEEVE FOULING • What is Fouling? • Accumulation of organic and inorganic material on the quartz surface • Absorbs UV light and decreases UV dose available for disinfection • All water fouls submerged surfaces • Rate of fouling influenced by various site-specific factors (water quality, hydraulics and velocities, sleeve surface condition)
LAMP AGING • As lamps age the amount of UV output decreases • UV systems should be designed to deliver the required dose at the end of lamp life (EOLL) to ensure disinfection is met under worst case conditions • EOLL should be independently validated to guarantee the system meets the disinfection requirements
UV SYSTEM VALIDATION • As microbes flow through a UV reactor they will all follow a different path • Some will receive a high dose and some a lower dose • To account for these differences, “Validated” reactors should be used • “Validation” involves a full-scale test of the UV system involving live microbes
