DIN EN 16713-3:2016-08 EN 16713-3:2016 (E) 4 1 Scope This European Standard specifies requirements and test methods for equipment and means of pool water treatment utili
22、zed in domestic swimming pools. This standard applies for swimming pools as defined in EN 16582-1 and will be read in conjunction with it. This standard does not apply to: pools for public use covered by EN 15288-1; spas for domestic or public use; paddling pools according to EN 71-8; natural and na
23、ture like pools. NOTE For filtration systems see EN 167131 and for circulation systems see EN 167132. The purpose of this standard is furthermore to ensure a consistently high quality of pool water in terms of hygiene in order to prevent damage to human health, particularly as a result of pathogens.
24、 At the same time, account is also to be taken of the well-being of the bathers (e.g. by minimizing the side effects caused by disinfectants). To this end, requirements are specified for water quality and water treatment. 2 Normative references The following documents, in whole or in part, are norma

32、 upon the pH-value Note 1 to entry: In the pH-range relevant in the pool application, these forms are HOCl/OCl-. 3.9 active chlorine proportion of free chlorine available as the biologically active hypochlorous acid (HOCl) at a given pH 4 Requirements 4.1 General Depending on the equipment being ins
33、talled and type of chemicals used, the necessary instructions and safety requirements (e.g. hazards of using chemicals inappropriately) shall be provided to the pool owner. DIN EN 16713-3:2016-08 EN 16713-3:2016 (E) 6 Pool water treatment is essential for the safety of the users but incorrect treatm
34、ent can also be the cause of various disorders (e.g. stains, discolorations, corrosion). The different problems related to improper pool water treatment or materials are listed in EN 16582-1:2015, Annex D (as an example for polyester shells but can be in a similar way for other pool materials e.g. l
35、iner, paint, tiles, mineral coating and pool equipment). 4.2 Fill water specifications Water that is obtained from a mains water supply is deemed to be suitable as fill water without testing. Water that is not obtained from a mains water supply should be tested for suitability and treated, if necess
36、ary. The following maximum values are recommended for the fill water: iron: 0,1 mg/l; copper: 0,2 mg/l; manganese: 0,05 mg/l; polyphosphate as phosphorus: 0,01 mg/l; nitrates: 50 mg/l. If these values are exceeded it is recommended to treat the water to achieve the recommended values. Phosphates int
37、roduced into the swimming pool water both with the fill water, and by the swimmers, promote algal growth. By optimization of flow, treatment (e.g. filtration and flocculation) and operation, the growth of microorganisms can be reduced together with the reduction of the phosphates. 4.3 Physical and c
38、hemical pool water requirements The following parameters ensure good quality bathing water. To ensure that these parameters can be achieved and maintained, the following shall be considered: a) pool design according to EN 16582 (all parts) and EN 16713-1 and EN 16713-2; b) pool installation accordin
39、g to EN 16582 (all parts) and EN 16713-1 and EN 16713-2; c) pool operation and maintenance; d) physical and chemical parameters should be checked regularly with suitable measuring equipment. Basic parameters for good quality bathing water are the pH value, free chlorine (or alternate disinfectants)
40、and combined chlorine (if applicable). If chlorine is not used or actively measured, the redox potential is one method of measurement.

43、r appropriate parameters may be considered. aWhen using organic compounds this value may be higher. bIf national regulations allow 100 mg/l then a suitable treatment should be applied (e.g. dilution). cSubject to the flocculant(s) used (if any). dWhen pH is greater than 7,5 the free active chlorine
44、is less than 50 %. eNatural water sources may introduce water colouration. fIntentional water colouration is excluded. 4.4 Flocculation/coagulation The finest of dirt particles, hardly visible or invisible, may be present in the water. Due to their very small size these can pass through the filter u
45、nder certain circumstances. In order to prevent this, the smallest of dirt particles could be converted into larger particles with the help of a flocculation agent. The use of flocculants/coagulants has long been used to assist in the enhancement of water quality. It is particularly relevant in the
46、removal of microorganism, e.g. Cryptosporidium cyst, which occurs in human faeces and is virtually impervious to disinfection. Consequently it shall be removed by filtration. The following substances are commonly used as flocculants/coagulants: a) aluminium based coagulant, as in EN 15031; b) iron b
47、ased coagulant, as in EN 15797; Special caution is needed with the use of iron based coagulants, to avoid the development of corrosion and stains. These substances all form a gelatinous precipitate by hydrolysis and shall be removed by cleaning. DIN EN 16713-3:2016-08 EN 16713-3:2016 (E) 8 Flocculan
48、ts are commonly used with granular media filters when necessary, however they are not mandatory. Alternative flocculants can be used, but shall comply with the general requirements regarding effectiveness, reaction and residual effect. The level of contamination of pool water in domestic pools is ve
49、ry small in comparison with commercial pools. It may be used in certain cases but generally flocculation/coagulation is not required on a permanent basis. 4.5 Disinfection 4.5.1 General In order for a disinfectant to work safely and reliably, it shall be equally effective against viruses, bacteria, fungi and parasites. Indications for the microbiological parameters providing effective disinfection of the pool water is in Annex B. When choosing a disinfectant, differing advantages and dis
