EN 16713, Domestic swimming pools Water systems, currently comprises: Part 1: Filtration systems Requirements and test methods; Part 2: Circulation systems Requirements and test methods; Part 3: Water treatment Requirements. According to the CEN-CENELEC Internal Regulations,

16、 the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, La

BS EN 16713-3:2016EN 16713-3:2016 (E) 4 1 Scope This European Standard specifies requirements and test methods for equipment and means of

18、 pool water treatment utilized 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

19、 to EN 71-8; natural and nature 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, particularl

20、y as a result of pathogens. 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

26、ter quality through physical and chemical actions 3.2 pool water water in the swimming or bathing pool 3.3 disinfection killing or inactivating certain microorganisms 3.4 filtrate water after the filtration process 3.5 fill water water used for the initial filling and for topping up 3.6 flow Q volum

28、te ion OCl-) depending 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 t

29、he equipment being installed 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. BS EN 16713-3:2016EN 16713-3:2016 (E) 6 Pool water treatment is essential for the safety of the users but

30、 incorrect treatment 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

31、 materials e.g. liner, 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 t

32、reated, if necessary. 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 value

33、s. Phosphates introduced 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

34、.3 Physical and chemical 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 inst

35、allation according 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 alternat

36、e disinfectants) and combined chlorine (if applicable). If chlorine is not used or actively measured, the redox potential is one method of measurement.

40、ve chlorine 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

41、the filter under 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 rele

42、vant in the 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 1503

43、1; b) iron based 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. BS EN 16713-3:2016EN 16713-3:2016 (E) 8 Fl

44、occulants 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 pool

45、s is very 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, bac

46、teria, 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 disadvantages as regards handling, storage, transport, influence on pH value, etc. shall be taken into a

47、ccount. The safe, simple and economic operation should be at the forefront of that choice. In addition, the disinfectant should react very quickly, have a long-lasting effect (residual effect), as well as be easily and quickly measurable. Taking all of these requirements into consideration, the reco

48、mmended reliable and suitable disinfectant is chlorine or bromine. The chlorine may be supplied in a gaseous, liquid (made onsite or delivered ready-made) or solid form. In order to minimize and reduce disinfectant by-products, special attention should be paid to an effective filtration (see EN 1671

49、3-2). The disinfection of the pool water may require the installation of disinfection equipment. The disinfectant shall be added to the filtrate either using dosing pumps, erosion/soaker feeders, in situ electrochlorination systems, control valves, or other suitable methods. An automatically controlled feeder unit and equipment for determining and recording parameters such as free chlorine, the Redox potential and pH value may also be installed. NOTE The automatic system may need periodic checks according to th
