Permutit is a complex inorganic salt having the formula Na2Al2Si2O8.xH2O. It is also known as sodium-aluminium silicate or zeolites.
Permutit is utilised in the "ion exchange method" for softening hard water. It is packed loosely in a big tank, over a layer of coarse sand. From the top, hard water is introduced into the tank which reaches the bottom and rises through the layer of Permutit. The cations, present in hard water, are exchanged for sodium ions.
