Anti-scalant (Option)
Dosing Amount
With use of the following table, the adjustment of the Anti Scalant
dosing amount can be determined with very good proximity. The op-
timum dosing could be calculated only after an exact water analysis
and with the help of a calculation program.
The typical dosing range is between 2 and 5 mg/l.
1°d.H. = 1.79° fr.H.
1°d.H. = 17.9 mg CaCO3/l
1°fr.H. = 10 mg CaCO3/l
NOTE
The use of Anti Scalant also has advantages when
conditioning (very) soft water. The operating time
between the cleaning cycles and the service life of
the membranes is prolonged due to the stabiliza-
tion of various ingredients of the untreated water.
• Standard adjustment of the dosing pump:
- Stroke length: 30%
- Frequency: 20%
• The operating mode must be set to "Manual".
• A service life of approx. 120 h per 30 l of mixture results.
NOTE
When the concentrate return line is open, select
the metered addition of the next higher hardness
classification.
For the classification "Very hard", the metered addi-
tion remains the same.
