16 Drinking Water Ordinance
Information according to § 16 and § 21
of the German Drinking Water Ordinance
The drinking water in this building is treated as followed:
Type of treatment:
Partial softening / (partial deliming)
Metering
Designation of the unit:
Installation site of the unit:
Metering of silicate substances
To minimize corrosiveness of the drinking water and
to prevent increased concentrations of heavy metals
Silicate concentration of your water, approx. mg/l
Max. permitted addition according to the German Drinking Water Ordinance: 15 mg/l calculated as SiO
2
(calculated as
SiO
2
)
Metering of phosphate substances
To minimize liming, corrosiveness of drinking water and
to prevent increased concentrations of heavy metals
Phosphate concentration of your water, approx. mg/l
Max. permitted addition according to the German drinking water ordinance: 2.2 mg/l calculated as P (calculated as P)
Metering to set the pH value
To minimize corrosiveness of the drinking water and
to prevent increased concentrations of heavy metals
pH value of your water
Limits according to the German drinking water ordinance: greater than 6.5 and less than 9.5
Metering of sodium hypochlorite or chlorine dioxide solution
To increase sanitary properties of drinking water
Chlorine - chlorine dioxide concentration of your water, approx. mg/l
Max. permitted addition according to German drinking water ordinance: 0.3 mg/l chlorine or 0.2 mg/l chlorine dioxide
Partial softening of drinking water by sodium ion replacement
To minimize liming
Hardness range of your water: Soft (less than 8.4°dH)
Moderate (8.4°dH - 14.0°dH)
Sodium concentration of your water, approx.:
mg/l
Max. permitted concentration according to German drinking water ordinance: 200 mg/l
