The Ultraviolet Spectrum

Understanding Ultraviolet Light

Categories of UV Light

How UV disinfection works

DNA Replication

UV light instantly alters the DNA of pathogens rendering them unable to reproduce (sterile)

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/cm2 (Millijoules per centimeter square)

mWsec/cm2 (Milliwatt second per centimeter square)

μWsec/cm2 (Microwatt second per centimeter square)

UV Dose Calculation

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

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

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

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

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”

Market leader in applications requiring NSF/ANSI Class A certification from 15 GPM to 1 MGD, both potable and waste.

Chosen by Boeing for POE purification on 787 Dreamliner

Engineered to achieve same performance as NSF/ANSI 55 Class A systems, but at lower pricing competitive with other non-certified systems that have UV intensity monitors

NEW for Residential and Light Commercial Markets

• 8 and 12 GPM Models• Quick and Easy Lamp

Changes• Visual Quartz Inspection takes

seconds

• Easy Installation• Priced competitively with

ordinary UV systems• Validated to dose of 40

mJ/cm2 at specified flow rate
