April 1997 editions, and
Aufbereitung von Schwimm- und Badebeckenwasser –
DIN 19643-4, February 1999

DIN 19643, April 1984 edition.
In keeping with current practice in standards published by the International Organization for Standardization
(ISO), a comma has been used throughout as the decimal marker.
Foreword
This standard has been prepared by Technical Committee IV 13 of the Normenausschuss Wasserwesen
(Water Practice Standards Committee).
The revision of DIN 19643, April 1984 edition, is in response to the future Infektionsschutzgesetz (German
Infection Prevention Act) and the Gesetz zur Neuordnung seuchenrechtlicher Vorschriften (German Act to
restructure German legislation on epidemics), in so far as these relate to water for swimming pools and public
baths. The Legionella pneumophila and trihalomethane (haloform) levels specified in the regulations that
implement the latter (the Schwimm- und Badebeckenwasserverordnungen of the Länder (German Länder
regulations on water used in bathing facilities)) have been incorporated into the present standard.
At the same time, the standard was divided into several parts, with DIN 19643-1 specifying general require-
ments, and subsequent parts dealing with different combinations of water treatment methods. Additional
parts will be added to the series as the state of the art develops.
To ensure proper application of this standard, water treatment systems should be designed, built and
monitored only by experienced specialists. Attention is drawn to DVGW-Arbeitsblätter (DVGW Codes of
practice) W 200 and W 201, which specify procedures for certifying water treatment experts.
Amendments
This standard differs from DIN 19643, April 1984 edition, as follows.
a) The standard now consists of several parts.
b) The combined method in the present standard has been included.
c) The standard has been brought into line with the state of the art.

1 Scope
In conjunction with DIN 19643-1, this standard specifies a method of treating water in bathing facilities
(except therapeutic pools and hot whirlpool baths) that combines coagulation, filtration, adsorption on
granulated activated carbon treatment and chlorination.

3 Principle
First, dispersed colloidal impurities are destabilized by coagulation with iron(III) or aluminium salts and
orthophosphates are precipitated, the pH value of the raw water being kept within a range consistent with the
type of coagulant used. The mixture of iron(III) phosphate or aluminium phosphate and colloids is then removed
by filtration, the redox potential being kept at not less than +650 mV.
At the subsequent stage, fully dissolved organic compounds are adsorbed on granular activated carbon and
the concentration of chlorine reaction by-products is reduced. The filtrate is then chlorinated and fed to the bath
or pool.

The load capacity factor, k, is 0,5 m , equivalent to a treated water volume of 2 m per person.

4 Procedure
4.1 Acidity adjustment
4.1.1 General
To achieve satisfactory coagulation, adjust the acidity, K (cf. DIN 38409-7), of the raw water to a given
S4,3
minimum value, unless the acidity of the filling water is high enough to prevent that of the raw water from
dropping below the minimum value. Acidity adjustments are to be made by adding an aqueous solution of
sodium carbonate or sodium hydrogencarbonate to the raw water via a feeder.
4.1.2 Reagents
The reagents to be used for the acidity adjustment are sodium carbonate (as in DIN EN 897) or sodium
hydrogencarbonate (as in DIN EN 898).
4.1.3 Minimum acidity
3
When the method specified in this standard is used for bathing facilities, K shall be equal to 0,7 mol/m .
S4,3
4.1.4 Check
After the reagents have been added and thoroughly dispersed, determine the acidity to check for compliance
with the value specified in subclause 4.1.3.
4.2 pH value adjustment
4.2.1 General
To ensure satisfactory coagulation and adequate disinfection with the lowest possible consumption of disin-
fectant, adjust the pH value of the water to a specified value using a feeder which automatically controls the
pH value. The reagents added shall be thoroughly mixed with the water before they reach the pH sensor and
the sampling point.
4.2.2 Reagents
The following reagents shall be used to adjust the pH value:
1) If the pH value of the raw water is too low:
a) sodium carbonate (as in DIN EN 897) or
b) sodium hydroxide (as in DIN EN 896).
2) If the pH value of the raw water is too high:
c) carbon dioxide (as in DIN EN 936),
d) hydrochloric acid (as in DIN EN 939),
e) sulfuric acid (as in DIN EN 899) or
f) sodium hydrogensulfate.
4.2.3 pH range
The pH value shall be between 6,5 and 7,2 if aluminium salts are used for coagulation, and between 6,5 and
7,5 (or up to 7,8 in the case of seawater) if iron salts are used.
4.2.4 Check
After the reagents have been added, check whether the pH value is within t 0,1 of the specified value using a
pH meter.
4.3 Stabilization of redox potential of filtrate after coagulation
4.3.1 General
To minimize the concentration of microbes taken up by the granular activated carbon filter, maintain the redox
3
potential at not less than + 650 mV. If it drops below this value, automatically add at least 1 g/m of chlorine to
the raw water prior to adjusting the pH value to achieve the required period of action, and report the fault.
4.3.2 Check
Throughout the entire filtering operation, use a stationary measuring instrument to measure the redox potential
of the coagulation filtrate against an Ag/AgCl 3,5 mol/l KCl electrode to ensure compliance with the value in
subclause 4.3.1.
4.3.3 Recording
Continuously measure and record the redox potential, and at the beginning and end of each bathing session,
enter the values for raw water against item 12 in the log book shown in table 5 of DIN 19643-1, April 1997 edition.
