Antiscalant

The drinking water for the metering solution is taken from the sampling tap for drinking
water (1/4.21).
The antiscalant metering quantity can be set with a very good approximation using the following
table. The optimum quantity can only be calculated using a calculation program after a precise
water analysis has been carried out. The typical metering range lies between 2 and 5 mg/l.
Where water hardnesses are higher than 28°dH, special design is necessary.
If this design is not possible, the following setting is recommended: 5 mg/l RM5000 and 50%
yield, until the precise design is available.
Range of Water Hardness
1 (0°-7° dH)
2 (7°-14° dH)
3 (14°-21° dH)
4 (21°-28° dH)

2 (7°-14° dH)
3 (14°-21° dH)
4 (21°-28° dH)
Table 11 Metering of antiscalant at 50% yield
1 °dH = 1,79 °frH
1 °dH = 17,9 mg CaCO3/l
1 °frH = 10,0 mg CaCO3/l
