Treatment of water of swimming pools and baths - Part 2: Combinations of process with fixed bed filters and precoat filters
Aufbereitung von Schwimm- und Badebeckenwasser - Teil 2: Verfahrenskombinationen mit Festbett- und Anschwemmfiltern
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 2 applies in conjunction with DIN 19643-1; the following individual process combinations are defined in particular: - flocculation - filtration - chlorination; - flocculation - multi-layer filtration with adsorptive carbon - chlorination;- adsorption to powdered activated carbon - flocculation - filtration - chlorination; - flocculation - filtration - adsorption to granular activated carbon - chlorination; -flocculation - filtration - UV radiation - chlorination; - flocculation - multi-layer filtration with adsorptive carbon - UV radiation - chlorination; - adsorption to powdered activated carbon - precoat filtration - chlorination.
