Treatment of water of swimming pools and baths - Part 4: Combinations of process with ultrafiltration
Aufbereitung von Schwimm- und Badebeckenwasser - Teil 4: Verfahrenskombinationen mit Ultrafiltration
Overview
New findings in the field of swimming pool water and bath water hygiene as well as technical development of the corresponding treatment processes necessitated a revision of the standard series DIN 19643. As a result the standards - DIN 19643-1 "Treatment of water of swimming pools and baths - Part 1: General requirements"; - DIN 19643-2 "Treatment of water of swimming pools and baths - Part 2: Combinations of process with fixed bed filters and precoat filters"; - DIN 19643-3 ("Treatment of water of swimming pools and baths - Part 3: Combinations of process with ozonization"); - DIN 19643-4 "Treatment of water of swimming pools and baths - Part 4: Combinations of process with ultrafiltration" which have been prepared by Working Committee NA 119-04-13 AA "Schwimmbeckenwasser" ("Pool water") at the Water Practice Standards Committee (NAW) are now available. Part 4 applies in conjunction with DIN 19643-1; the following individual process combination is defined in particular: - flocculation - adsorption - ultrafiltration - chlorination. The process combination can be optionally expanded by one UV level.
