UV Pure Technologies develops UV disinfection systems using patented Crossfire Technology. The document discusses UV Pure's awards, customers, market focus on small decentralized applications, and how its Crossfire Technology offers advantages over conventional UV designs through features like self-cleaning elliptical reflectors and dual smart sensors. UV Pure offers a broad range of product lines for potable, wastewater, and reuse applications from 15 GPM to 1 MGD.

Market Focus Small Decentralized Applications: Under 1 MGD today; increasing to 5 MGD within two years Potable Small Community Use Small Municipality Use Mobile Applications – mining, camps, transportation (aerospace, shipping, trains) Waste Decentralized (Premier Tech – Eco Flo), parks, golf courses Small Municipal Reuse Washwater (Agriculture Canada) Australia – irrigation Green Roof applications

5. Understanding Ultraviolet Light The Ultraviolet Spectrum Categories of UV Light

6. How UV disinfection works DNA Replication UV light instantly alters the DNA of pathogens rendering them unable to reproduce (sterile)

7. UV Dose is the product of : Intensity X Residence Time (Quantity of UV Light per (Contact Time in UV Reactor) unit Area Falling on a Surface) UV Dose is expressed in mJ/cm 2 (Millijoules per centimeter square) mWsec/cm 2 (Milliwatt second per centimeter square) μ Wsec/cm 2 (Microwatt second per centimeter square) UV Dose Calculation

8. Factors Influencing UV Dose Water Quality Factors UV Transmittance (UVT) Turbidity Hardness & Water Chemistry – Quartz Sleeve Fouling Flow Rate Faster Flow means decrease in UV Dose Slower Flow means increase in UV Dose Lamp Age and Operating Temperature UV Lamps lose output (UVI) over time UV Lamps lose output outside optimal operating temp range

9. Water UV Transmittance (%UVT) The amount of UV light from a UV lamp that can transmit through a sample of water – usually reported for a path length of 1 cm. UVT is expressed in percentage value, %UVT The higher the %UVT- the more UV Light transmitted through water Distilled water = 99 %UVT Tap Water = 85-95% UVT 1cm water layer UV Light transmitting through the water

10. Turbidity (NTU) Turbidity is a measure of Suspended Solids in the water It is expressed in Nephelometric Turbidity Units (NTU) Turbidity levels over 1 NTU can shield microorganisms from the UV lights, making the UV disinfection less effective

11. Hardness & Iron High level of Hardness and Iron can contribute to significant Fouling and Scaling of Quartz Sleeve which in terms lowers the UV Transmittance affecting the overall disinfection performance Cleaning Mechanism is therefore necessary to eliminate the Fouling/Scaling problem

12. Why UV? Features & Benefits Broad-Spectrum microbial barrier Real-time monitoring for effective disinfection Low cost alternative No disinfection by-products Small footprint – easily retrofitted Easily serviced/maintained/monitored No environmental risk Low energy consumption “ UV disinfection is the silver bullet”
