(A) Zeolite method removes only cations ($\mathrm{C}{\mathrm{a}}^{2+}$and$\mathrm{M}{\mathrm{g}}^{2+}$ion) present in hard water
$2\mathrm{N}\mathrm{a}\mathrm{Z}+{\mathrm{M}}^{2+}\left(\mathrm{a}\mathrm{q}\right)\to \mathrm{M}{\mathrm{Z}}_2\left(\mathrm{s}\right)+2\mathrm{N}\mathrm{a}+\left(\mathrm{a}\mathrm{q}\right)(\mathrm{M}\to \mathrm{M}\mathrm{g},\mathrm{C}\mathrm{a})$
(B) Synthetic resin method removes cations ($\mathrm{C}{\mathrm{a}}^{2+}$and$\mathrm{M}{\mathrm{g}}^{2+}$ion) and anions (like$\mathrm{C}{\mathrm{l}}^{-},\mathrm{H}\mathrm{C}{\mathrm{O}}_3^{-},\mathrm{S}{\mathrm{O}}_4^{2-}$etc.)
