25、n. I.A. Background. Ultraviolet (UV) disinfection systems have gained increased acceptance for use in water treatment plants based on information that UV disinfection could cost-effectively inactivate Cryptosporidium. In addition, the Long T erm 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) has
26、 recognized UV disinfection as a best available technology for meeting the requirements of the rule. I.B. History. The need for a standard addressing UV disinfection systems was recognized by the American Water Works Association (AWWA) in November 2005. The committee was appointed for the task of st
27、andardization, and at the first inaugural meeting in June 2006, a committee was formed to develop a standard. The first edition was approved by the AWWA Board of Directors on June 10, 2012. This edition was approved on June 19, 2016. I.C. Acceptance. In May 1985, the US Environmental Protection Agen
28、cy (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the Water Research Fou
29、ndation (formerly AwwaRF) and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate products for use in, or in contac
30、t with, drinking water rests with individual states. Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, incl
31、uding 1. Specific policies of the state or local agency. 2. Two standards developed under the direction of NSF : NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. * American National Standards Institute, 25 West 43rd Stree

33、ng AWWA standards, Food Chemicals Codex, Water Chemical Codex,* and other standards appropriate to the state or local agency. Various certification organizations may be certifying products in accordance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certif
34、ication organizations within their jurisdictions. Accreditation of certification organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not reg
35、ulated by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on th
36、e certifier. ANSI/AWWA F110 does not address additives requirements. Therefore, users of this standard shall consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable standards. 2. Determine the status of certification by
37、all parties offering to certify prod- ucts for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. Conditions under which the UV disinfection system is to be operated must be evaluated carefully by the purchasers. The evaluati
38、on must include the determination of the hydraulic characteristics of the system in which the lamps will be installed and the electrical circuits required for the operation of the lamps, including the maximum and static differential pressures across the lamp and the range of flow through the UV syst
39、em under the most adverse operating conditions. Sensors (UV intensity and UV transmittance) are critical components for mak- ing UV disinfection a credible technology for municipal drinking water. For all sen- sors, both the frequency and specificity of calibration may vary by location and UV manufa
40、cturer. In designing UV facilities and specifying UV equipment, accessible, easy-to-use sensor calibration routines should be highlighted as part of any basic instrumentation package. Small changes in transmittance in low-UV-absorbing waters can significantly change UV dose delivery; where ultraviol
41、et transmittance (UVT) monitors are used as part of verifying adequate dose delivery, it is recommended the * Both publications available from National Academy of Sciences, 500 Fifth Street, NW, Washington, DC 20001.

42、onsider tightening UVT error limits above the minimum standard where UVT is high (e.g., 94 percent). III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being
43、considered. III.A. Purchaser Options and Alternatives. The following information shall be provided by the purchaser: 1. Standard usedthat is, ANSI/AWWA F110, Ultraviolet Disinfection Systems for Drinking Water, of latest revision. 2. Equipment requirements (Sec. 4.1). 3. Request for validation statu
44、s or an executive summary of the validation report (Sec. 4.3.5.2). 4. Details of other federal, state or provincial, and local requirements (Sec. 4.4.1). 5. Whether compliance with NSF/ANSI 61, Drinking Water System ComponentsHealth Effects, is not required (Sec. 4.4.1.1). 6. Request for factory tes
45、t results (Sec. 5.1.1.2). 7. Request for shop inspection by the purchaser (Sec. 5.1.1.3). 8. Request for on-site field representative (Sec. 5.2.2). 9. Request for a supplier check of equipment for correct installation and func- tion (Sec. 5.2.3). 10. Request for a required number of training materia
46、ls (Sec. 5.2.5.2). 11. Specify acceptance testing time requirements (Sec. 5.2.6). 12. Request storage requirements (Sec. 6.2.3). III.B. Laying Length. There is not a standard laying length for UV disinfection systems and because of this, interchangeability between various manufacturers may not be po
47、ssible without modification to the existing piping system. The purchaser is cautioned to obtain this information from the manufacturers for verification prior to purchase (Sec. 4.3.2.4). III.C. Testing. This standard requires the manufacturer to have third-party validation testing conducted on a ful
48、ly assembled system. If the purchaser desires that an additional validation test be conducted on the installed, fully assembled system, this requirement should be specified in the purchase documents (Sec. 4.6). III.D. Modifications to Standard. Any modification to the provisions, definitions, or ter
49、minology in this standard must be provided by the purchaser. Copyright 2017 American Water Works Association. All Rights Reserved. x I V. Major Revisions.
