29、sually include peripheral suction and an inlet, all within a single housing, that is designed to move a large volume of water at a high velocity, with or without the introduction of air 3.4 overflow channel channel designed to collect and conduct overflowing surface water Note 1 to entry: The water
30、can be transported to e.g. a water balance tank. 3.5 channel drain system fitted below within the overflow channel to collect the water from the overflow channel, when a balance tank is used 3.6 main drain outlet device incorporated on the bottom of the basin 3.7 suction chamber vessel between the s
31、uction outlet grille and the suction outlet piping, manufactured or field built 4 Requirements 4.1 Filtration system design The components of the hydraulic system shall be sized or designed or be in sufficient number to meet the maximum performance requirements of the filtration unit (pump and filte
32、r). 4.2 Filtration system nominal flow rate The filtration system nominal flow rate shall be designed according to the pool size, pool volume, shape, load and location in order to achieve sufficient water removal from the pool and distribution of water back into the pool. Where applicable, the volum
33、e of the overflow tank shall be included with the volume of the pool to give the total volume in the system. The total volume in the system is the volume used in all calculations. The circulation system will ensure the greatest possible mixing of the water in the pool basin in order to provide a uni
34、form distribution of chemical treatment and heat, making sure fine debris are kept in suspension as long as possible and that there are no “dead areas” where water movement is zero. The filtration system shall have a sufficient nominal flow rate to allow the total volume of water contained in the po
35、ol to be recycled in no longer than 8 h. The filtration system nominal flow rate Q is calculated: =TOVQT(1) where Q is the filtration system nominal flow rate in m3/h; BS EN 16713-2:2016EN 16713-2:2016 (E) 7 V is the pool volume in m3; TTOis the turnover time of the pool volume in h 4.3 Extraction o
36、f pool water 4.3.1 General The majority of the pollution within a swimming pool is found in the top layer of the pool water and therefore good surface water removal during pool operation is essential for efficient filtration and treatment of the water. Other systems can also be used to help the effi
37、ciency of the removal of the complete water volume (e.g. bottom main drain, etc.). 4.3.2 Overflow channel 4.3.2.1 Dimension of overflow channel and channel drains The cross section of the overflow channel shall be designed adequately to achieve sufficient temporary water storage. If the channel is t
38、o be used as a balance tank, it should be sufficiently sized to accommodate the effective volume required (see a) to d) in 4.3.2.3). The dimension and numbers of channel drains shall be designed according to the expected: a) water displaced by bathers; b) amount of water created by waves; c) nominal
39、 filtration system flow rate; d) water and air based pool features. The dimension of the channel drains shall be sufficient to allow water flow without pressure (under gravity only) and to minimize noise. The internal surface of the overflow channel shall be easily cleaned to prevent the build of so
40、lid, bacteria biofilm, etc. NOTE When overflow channels with a continuous slope are installed, the water can be extracted through one or more sufficiently designed channel drains at the lowest point. 4.3.2.2 Overflow channel cover The overflow channel cover shall be designed to avoid entrapment for
41、fingers and toes, be capable of taking the design flow of water and also be able to support the weight of the bathers. The cover shall collect the flow of water. National safety regulations shall also be considered. The cover should be removable for maintenance and cleaning. Where the cover is not r
42、emovable, an adapted cleaning system shall be provided. 4.3.2.3 Water balance tank The size of the water balance tank should consider the: a) amount of water displaced by bathers, or any submerged equipment; b) amount of water created by waves; c) losses of water due to splashing, evaporation, filte
43、r backwashing; d) minimum water level in order to prevent air suction into the pump. BS EN 16713-2:2016EN 16713-2:2016 (E) 8 NOTE Water for filter backwashing can be also taken from the pool. The water balance tank should have: access hatches to allow for cleaning and maintenance. The internal finis
44、h of the tank shall be easily cleaned so as to prevent the build-up of solids, bacteria etc.; venting or connection to the atmosphere; overflow drain; connection point for filling up water. 4.3.3 Skimmer 4.3.3.1 General With a skimmer, the water will be removed of one or more positions at the pool.
45、The number of skimmers depends on, but is not limited to, the following: surface area; pool shape; skimmer opening size; nominal flow rate. A flow rate ratio of approx. 2/3 through the skimmers and approx. 1/3 through the bottom drain(s) or additional outlets is recommended. The hazard of suction at
46、 the main drain(s) according to 4.4 shall be considered. 4.3.3.2 Installation of skimmers When installing more than one skimmer, the skimmers shall be installed to ensure balanced flow in each skimmer. 4.3.3.3 Skimmers in outdoor pools The positioning of skimmers should be opposite to the main wind
47、direction. 4.3.3.4 Construction requirements In case the skimmer lid can be walked on, the lid shall withstand the mechanical load. The skimmer lid shall be installed securely to prevent unintentional removal. 4.3.4 Main drain The main drain shall be used in combination with surface water extraction
48、 for filtration purposes. One or more main drains can be installed in a pool. To use the main drain as pool drain it shall be installed on the deepest area of the basin. 4.4 Risk of suction entrapment 4.4.1 General Suction devices shall be designed and installed so as to minimize the potential for e
49、ntrapment of the user. BS EN 16713-2:2016EN 16713-2:2016 (E) 9 Water speed at fully submerged suction outlets should be 0,5 m/s. Hair entrapment tests shall be performed on suction devices according to 5.3. Safety requirements a) to c) are not applicable to: skimmers, because they are vented (see 4.4.3) and partly above the water level; integrated swim jet systems, because the users are pushed away from the outlet, as defined in 3.3 by the action of the inlet. Additionally at least one of the following req
