31、 Treatment Units Drinking water treatment units Health effects 1 General 1.1 Purpose It is the purpose of this Standard to establish minimum requirements for materials, design and construction, and performance of point-of-use and point-of-entry drinking water treatment systems that are designed to r
32、educe specific health-related contaminants in public or private water supplies. Such systems include point-of-entry drinking water treatment systems used to treat all or part of the water at the inlet to a residential facility or a bottled water production facility, and includes the material and com
33、ponents used in these systems. This Standard also specifies the minimum product literature and labeling information that a manufacturer shall supply to authorized representatives and system owners, as well as the minimum service-related obligations that the manufacturer shall extend to system owners
34、. 1.2 Scope The point-of-use and point-of-entry systems addressed by this Standard are designed to be used for the reduction of specific substances that may be present in drinking water (public or private). These substances are considered established or potential health hazards. They may be microbio
35、logical, chemical, or particulate (including filterable cysts) in nature. It is recognized that a system may be effective in controlling one or more of these contaminants, but systems are not required to control all. Activated carbon filter systems covered by this Standard are not intended to be use
36、d with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. 1.3 Alternate materials, designs, and construction While specific materials, designs, and construction may be stipulated in this Standard, systems that incorporate alternate
37、materials, designs, and construction may be acceptable when it is verified that such systems meet the applicable requirements stated herein. 1.4 Minimum requirements A system as defined in this standard shall meet the applicable requirements of 4, 5, 6, and 8, plus at least one performance claim as
38、described in 7. A component as defined in this standard shall meet the requirements of 4 and 8. If the component is pressure-bearing, it shall also meet the applicable requirements of 5. A commercial modular system as defined in this standard shall meet the applicable requirements of 4, 5, 6, and 8,
39、 plus at least one performance claim as described in 7. Manifolds of commercial modular systems shall meet the requirements of 4, 5 (if pressure bearing), and 8, and shall be evaluated as stand-alone components. Manifolds shall have a minimum internal diameter such that the water velocity in the man
40、ifold will not exceed 3 m (10 ft) per second (which can be calculated based upon the system flow rate 2017 NSF NSF/ANSI 53 2016 2 and the manifold internal diameter). Individual modular elements evaluated as a manifold and modular element combination shall meet the applicable requirements of 4, 5, 6
41、, and 8, plus at least one performance claim as described in 7. 1.5 Chemical and mechanical reduction performance claims 1.5.1 All performance claims shall be verified and substantiated by test data generated under the requirements of this Standard. 1.5.2 When performance claims are made for substan
42、ces not specifically addressed in the scope of this Standard or for those substances not specifically addressed but falling under the scope of NSF/ANSI 53, those claims not specifically addressed in the Standard shall be so identified. 1.6 Treatment train A system that contains multiple, sequential
43、treatment technologies for a performance claim under this Standard shall meet the applicable requirements as described in Annex I. 1.7 Standard review This Standard shall be reviewed at least once every five years. The review shall be conducted by the NSF Joint Committee on Drinking Water Treatment
