COMMON UV DISINFECTION APPLICATIONS

• Disinfection of Primary Treated Effluent (e.g. 5,000 FC/100 ml)

• Unfiltered Secondary Effluent (e.g. 200 FC/100 ml)

• Tertiary Effluent (following sand, disk, membrane filter)

• Disinfection for WW reuse and reclamation e. . 2.2 TC/100 ml

• Photolysis / Oxidation for specific contaminants in WW (e.g. NDMA)

•

UV Transmission Scale:

• Primary Effluent• Blended Effluent

• Lagoons

• Secondary Effluent• Filtered Effluent

• WW Reuse

• Post-membrane• High-level reuse

• Contaminant destruction

Basic principals of UV



WHAT IS ULTRAVIOLET LIGHT?

UV-A (Long Wave UV):

315-400 nm

-

280-315 nm

UV-C (Short Wave UV):

200-280 nm



How does UV work?

• The UV energy

AFFECTING PERFORMANCE – UV TRANSMITTANCE (UVT)

• The ratio of light enteringthe water to that exiting thewater

• Length of 1 cm

Examples:

Filtered Surface Water:

85 – 95%

Unfiltered Surface Water:

80 – 95%

Secondary Wastewater:

50 – 70%



UV Dose

DOSE

UV Dose is expressed in: µWsec/cm2 (Microwatt seconds/cm2)

mWsec/cm2 Milliwatt seconds/cm2

mJ/cm2 (Millijoules/cm2 )

UV Dose = Disinfection energy applied to water



UV Lamps – Low Pressure

• UV output isLow Pressure Lamp UV Output

primarily 254

nanometers -monochromatic

• 254 nm

ideally suited tomicrobial



UV Lamps – Medium Pressure

• Broad spectrum of UVMedium Pressure Lamp UV Output

output (<200 to >600

nm) - polychromatic

• Though less efficient,medium pressure

lamps emit more UVenergy - a ow ng verycompact treatmentsystems capable oftreatin lar e flows



Traditional UV Solutions Have Forced a Compromise

Low energy solution required significantly

more lamps (LPHO lamp technology)

Solution with small footprint, fewer lamps and

lower maintenance required MP lamp

technolo , sacrificed electrical efficienc

With TrojanUV Solo LampTM Technology

you can have best of both
