2 AGENDA Introduction Core Business UV Basics and Advantages Capabilities Questions

3 3 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 FOUNDING PRINCIPLE

4 4 A Global Environmental Business with staff of 650 CanadaLondon & Guelph (400) USMultiple locations (175) Europe Multiple locations (50) ChinaMultiple 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-H 2 O 2 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 TODAY

5 5 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)

6 6 Microorganisms in drinking and waste water represent a risk to Public Health. (Giardia)(Cryptosporidium) VirusesBacteria (E.coli)(Hepatitis, Polio) Protozoa DISINFECTION WATERBORNE MICROORGANISMS

7 7 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 DISINFECTION HOW DOES IT WORK? UV Energy DNA Nucleic Acid Cell Wall Cytoplasmic Membrane

8 8 Chlorine CT Chlorine Disinfection UV Disinfection Typical Chlorine CT for Giardia Typical Design UV dose = 40mJ/cm 2 UV Dose Adenovirus Dual Protection Giardia Rotavirus Poliovirus Hepatitus A Legionella E.coli Streptococcus Crypto UV AS PART OF MULTI-BARRIER STRATEGY

9 9 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

13 13 UV DESINFECTION SYSTEMS

14 14 UV SYSTEM KEY COMPONENTS UV Lamps Quartz Sleeves Reactor Chamber Sleeve Wiping System Control Panel with Visual Displays & Alarms Power Supply (Ballasts) UV Sensor

15 15 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

16 16 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 ADVANTAGES OF UV DISINFECTION

17 17 ULTRAVIOLET (UV) LIGHT

18 18 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 DNA Nucleic Acid Cell Wall HOW DOES UV WORK?

19 19 ACGTAAA TGCATTT C G G C ACGTAAA TGCATTT C G G C UV DNA Double Strand Dimerization of Thymine Nucleotides dimer DNA MECHANISM OF UV DISINFECTION

20 20 UV Dose = Intensity x Retention Time (mWs/cm 2 ) (mW/cm 2 ) (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) DEFINITION OF UV DOSE

21 21 IntensityRetention Time Equipment Parameters Lamp Spacing Lamp Age Sleeve Fouling (iron, calcium, etc) Reactor Design Water Quality Factors (related to upstream process) UV Transmittance Turbidity Solids Flow Rate FACTORS AFFECTING UV DOSE

22 22 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 UV Transmission Scale: 20% - 50%50% - 70% > 70% 20% - 50% 50% - 70% > 70% Primary Effluent Blended Effluent Lagoons CSO, SSO Secondary Effluent Filtered Effluent WW Reuse Fixed Film Effluent Post-membrane High-level reuse Contaminant destruction UV TRANSMITTANCE

23 23 UV Lamp Scatter UV Light Complete Penetration Incomplete Penetration limits DNA damage Shade Particles THE EFFECTS OF PARTICLES

24 24 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) QUARTZ SLEEVE FOULING

25 25 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 LAMP AGING

27 27 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 UV SYSTEM VALIDATION

28 28 Step 1: Develop UV dose response data under controlled laboratory conditions Collimated Beam Sample Stirrer UV Lamp Viable Microbial Population Dose Challenge Organism Dose Response Dose Response Curve BIODOSIMETERY DETERMINATION

29 29 Step 2: Inject test organism into full scale reactor to measure inactivation. Use organism from same culture. Organisms in (N o ) Organisms out (N) UV Reactor BIODOSIMETERY DETERMINATION
