70,000 litres of water per day, if the water contains the following impurities:
Example 9.33. Calculate the annual cost of slaked lime and soda for treating
100 ррт
Mg(HCO),
CaSO,
MgSO4
SiO,
CaCO3 = 280 ppm
NaCl %3D 35 ррт
110 ррт
%3D
= 80 ppm
MgCl, = 138 ppm
Fe,0, = 55 ppm
Purity of slaked lime is 85% and that of soda is 100%. Slaked lime costs 780
per quintal and soda for 400 per quintal.
