Q. Write phosphate conditioning method for water softening with suitable chemical reactions. How it is different from soda lime method.
Ans.
Phosphate conditioning: In high pressure boilers, scale formation can be avoided by adding sodium phosphate, which reacts with hardness causing substance of water, forming non adherent and easily removable soft sludge of calcium and magnesium phosphates, which can be removed by blow down operation.
3MCl2 + 2Na3PO4 = M3 (PO4)2 + 6NaCl
Where M = Ca+2 or Mg+2
Mainly employed phosphates are:
1. Sodium dehydrogenate phosphate (acidic) Na2HPO4
2. Disodium hydrogen phosphate (weakly acidic) Na2HPO4
3. Trisodium hydrogen phosphate (alkaline) Na3PO4.
