Ultraviolet disinfection is a form of wastewater treatment. It is commonly USED in garden pond filtration systems to kill algae. UV is also used for treatment of water after it leaves a Reverse Osmosis Holding Tank.

Large scale URBAN UV wastewater treatment is performed in cities such as Edmonton, Alberta.

UV Dosing:

One method for gauging UV effectiveness is to compute uv dose. The U.S. EPA publishes UV doseage guidelines

Doseage INVOLVES the following PARAMETERS:

• flow rate (reflecting CONTACT time)
• transmittance (reflects light reaching the target)
• turbidity (“cloudiness”)
• lamp age (reflects reduction in UV intensity)
• lamp fouling
• % active lamps (reflects lamp outages in each lamp bank)
