10、 AA Schwimmbeckenwasser of the Normenausschuss Wasserwesen (Water Practice Standards Committee). This revision was prompted by the need to merge Parts 2 and 5 of the DIN 19643 series of standards from 1997 and 2000, respectively, into a new single part, and by the need to take changes in the general
11、 requirements for the treatment of water of swimming pool and baths as specified in DIN 19643, Part 1 into account. This new standard focuses largely on describing those basic process combinations that include a fixed bed filter (referred to in the following as granular media filter) or precoat filt
12、er as one of the treatment stages. The process combinations specified in this standard illustrate various ways to implement methods of preventing and removing disinfection by-products. In addition to the application of powdered activated carbon and granular activated carbon in the downstream sorptio
13、n filters and adsorptive carbon in the top layer of a multi-layer filter, as was common up to now, the application of ultraviolet radiation as a method of eliminating chloramine compounds has now been included as well. The following individual process combinations have been defined: Flocculation fil
14、tration chlorination Flocculation multi-layer filter using adsorptive carbon chlorination Adsorption by powdered activated carbon flocculation filtration chlorination Flocculation filtration adsorption by granular activated carbon chlorination Flocculation filtration ultraviolet radiation chlorinati
15、on Flocculation multi-layer filtration using adsorptive carbon ultraviolet radiation chlorination Adsorption by powdered activated carbon filtration using precoat filters chlorination. Other process combinations can be used as a function of the application. DIN 19643 consists of the following parts,
16、 under the general title Treatment of water of swimming pools and baths: Part 1: General requirements Part 2: Combinations of process with fixed bed filters and precoat filters Part 3: Combinations of process with ozonization Part 4: Combinations of process with ultrafiltration Further parts may be
17、added to this standard in future. In order to ensure that the requirements set down in this standard are met, and bearing in mind economic aspects, it is recommended that only experienced specialist companies with appropriate references be DIN 19643-2:2012-11 4 commissioned to plan, build and instal
18、l the treatment facilities. Furthermore, effectiveness of the treatment should be checked at regular intervals by experienced staff. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN (and/or DKE) shall not be held responsible fo
19、r identifying any or all such patent rights. Amendments This standard differs from DIN 19643-2:1997-04 and DIN 19643-5:2000-09 as follows: a) the contents of the two standards have been merged; b) a detailed description of the methods used to eliminate disinfection by-products has been added; c) the
20、 process combination using UV radiation has been included; d) the contents of the standard have been brought in line with state-of-the art technology; e) normative references have been updated.

Where the filling water has an increased phosphate concentration, it may be necessary to precipitate phosphates by flocculation filtration before feeding the water into t
47、he water tank. 4 Process stages 4.1 Acid neutralizing capacity adjustment 4.1.1 General To achieve satisfactory flocculation, the acid neutralizing capacity (KS4,3as defined in DIN 38409-7) of the raw water shall be maintained at a given minimum value, depending on the type of flocculant used. This
48、can be achieved by adding suitable filling water and/or chemicals to increase the acid neutralizing capacity. 4.1.2 Compounds used to adjust acid neutralizing capacity a) Sodium carbonate (soda) as in DIN EN 15362; b) sodium hydrogen carbonate as in DIN EN 15075; c) calcium carbonate, in solid form,
49、 as in DIN EN 15798 (to be used as filtration medium). DIN 19643-2:2012-11 8 4.1.3 Acid neutralizing capacity values a) When applying the respective process combination for bathing facilities other than spa pools (bubbling pools) (with their own treatment facility): KS4,3 0,7 mol/m3; b) when applying the respective process combination for spa pools (bubbling pools) with their own treatment facility: KS4,3
