CONSTITUENTS | QUANTITY IN ppm | MULTIPLICATION FACTOR | CaCO3 EQUIVALENT |
---|---|---|---|
Ca(HCO3)2 | 81 | 100162 | 81×100162=50 |
MgSO4 | 60 | 100120 | 60×100120=50 |
MgCO3 | 42 | 10084 | 42×10084=50 |
Ca(NO3)2 | 82 | 100164 | 82×100164=50 |
Temporary hardness = Hardness caused due to[Ca(HCO3)2 + MgCO3] =50+50=100 ppm
