Impurities (mg/lit) Multiplication factor CaCO3 equivalent (mg/lit)
$Ca(HCO_3)_2 = 35.2\ mg/lit $ $\frac{100}{162}$ $ 35.2 \times \frac{100}{162} = 21.728$
$Mg(HCO_3)_2 = 52\ mg/lit $ $\frac{100}{146}$ $52 \times \frac{100}{146} = 35.616 $
$CaCl_2 = 22.2\ mg/lit $ $\frac{100}{111}$ $22.2 \times \frac{100}{111} = 20$
$KCl = 15.55\ mg/lit $ - -

$Lime …
