Validation Management• Test and Verify the “Dose” Delivery Performance of UV reactorswithin their prescribed operating envelope of flow rate, power,UVT, etc.• Cryptosporidium, Giardia and/or virus removal credits for drinkingwater systems – validations must be done at full scale• Trend is toward testing at off-site facilities – Two are in the U.S.:• Portland, OR• Johnstown, NY (HDR|HydroQual UV Center)• The equipment supplier generally manages this validation requirementwithin the procurement process for the systems it offers commercially• Owner/engineer can also manage – generally with a pre-purchaseapproach.Regulatory interaction and approval – importantto the process
Validation Protocols - Drinking Water andReusevion is• US EPA Ultraviolet Disinfection Guidance Manual(UVDGM, 2006). M• Controls the drinking water market – nationally and, in large part,internationally.• NWRI/AwwaRF (2003) “UV Design Guidelines for Reuseand Drinking Waters”. (3 rd Edition Announced August2012)• Controls the reuse market – with a mix of UVDGM QAprotocols. International trend to use UVDGM for reusevalidations
