#2045 - "Utilizing Ultraviolet Disinfection in Drinking Water Facilities"    IEPA#5406

Delivered on: 6/8/2011
RTC Hours: 1 Total Hours: 1
Presented by: Patrick Bollman, P.E., Engineered Treatment Systems (ETS)

In November 2006, the United States Environmental Protection Agency released the Ultraviolet Disinfection Guidance Manual for the Final Long Term 2 Enhanced Surface Water Treatment Rule ( This document (UVDGM) was generated to provide technical information on how UV should be applied for disinfection of public water systems. It is important to note that it is not a regulation just guidance on how to implement UV.

The Webinar will focus on the following aspects of UV disinfection:

• UV fundamentals – what is UV, how is UV light generated, what UV does and how it works, how organisms respond to UV, and a comparison of available lamp types.
• Equipment selection – what manufacturers will require to provide an adequately sized system including flowrates (peak, average, and minimum), water quality (transmittance – how much light passes through the water,
soluble iron and manganese, hardness), required disinfection/dose (are you trying to receive cryptosporidium/giardia credits), and existing plant hydraulics (not many new DW plants are being constructed, therefore existing hydraulic grade lines often will help dictate the size of equipment that is required).
• Installation requirements for chambers and cabinets.
• Maintenance items that will need attention including lamps, sleeves, wiper rings, UV intensity monitors, and power supplies.
• Validation requirements – what/how UV manufacturers get their systems approved.
• Regulatory summary and why municipalities might/have to implement UV.
