22、wesen (Water Practice Standards Committee). DIN 19643 consists of the following Parts, 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

23、ozonization Part 4: Combinations of process with ultrafiltration Further parts may be 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

24、appropriate references be commissioned to plan, build and install 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

25、patent rights. DIN (and/or DKE) shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN 19643-1:1997-04 as follows: a) requirements for the supply water and pool water have been revised and supplemented; b) requirements for therapeutic p

26、ools and pools have been revised; c) specifications on the treatment facility design calculations (nominal load, minimum overflow, flow rates, special cases) have been rewritten; d) ultrafiltration plants have been included; e) chemical feed requirements have been revised; f) information on process

27、combinations for the treatment of water of swimming pools and baths (k values) have been modified; g) specifications on the inspection of water quality during operation (inspection periods, sampling points and sampling, scope of tests, evaluation and measures to be taken when legionella are detected

28、) have been revised and/or supplemented; h) the contents of the standard have been brought in line with the state-of-the art; i) normative references have been updated.
