DISINFECTION WATERBORNE MICROORGANISMS


       Microorganisms in drinking and waste water
       represent a risk to Public Health.


 Bacteria   Viruses                       Protozoa
(E.coli) (Hepatitis, Polio)   (Giardia)              (Cryptosporidium)




                                                                         6
UV DISINFECTION HOW DOES IT WORK?


UV light at the 254 nm
wavelength penetrates the
cell wall of the
microorganism.
                                           UV Energy
The microorganism is
“inactivated” and rendered
unable to reproduce or       Cell Wall
infect.

 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


                                                                    15
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

ULTRAVIOLET (UV) LIGHT




                         17
    HOW DOES UV WORK?



• UV light penetrates the cell wall
• The UV energy permanently
  alters the DNA of the
  microorganism                                   UV Energy
• Microorganisms are
  “inactivated” and unable to         Cell Wall
  reproduce or infect

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)




                                                            20
FACTORS AFFECTING UV DOSE


              Intensity           Retention Time
Equipment Parameters
• Lamp Spacing                • Reactor Design
• Lamp Age
• Sleeve Fouling (iron, calcium,
etc)
Water Quality Factors
(related to upstream process) • Flow Rate
• UV Transmittance
• Turbidity
• Solids

                                                   21
     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




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


                                                                                22

       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)




                                                                                  24
     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




                                                                                 25

    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
