Patent ID: 7862726

Claim:
A method for regenerating ionic exchange resins used for softening water, comprising the step of feeding a flow of brine (S) along a respective first direction (A) in a housing compartment ( 2 ) of said resins ( 3 ); characterised in that said step of feeding said flow of brine (S) comprises the sub-steps of delivering the flow of brine (S) at a calculated velocity on the section surface of each resin ( 3 ) of between 1.90 ml/min/cm 2 and 2.40 ml/min/cm 2 and subsequently feeding a first flow of water at a velocity calculated on the section surface of each resin ( 3 ) of between 0.80 ml/min/cm 2 and 1.25 ml/min/cm 2 .
