Abstract

The present application relates to a reformation process of brine solution formed following loading of the ion-exchange resin used for water softening. The cyclic, continuous process for brine reformation comprising the steps: (I) a brine solution containing bivalent cations, in particular calcium, magnesium, iron and manganese ions, is transferred to a Hardness Precipitation System (Station 1) in which, at a suitable pH, same cations are removed as carbonate and/or sulphate salts, in a precipitation form, resulting in a semi-reformed brine solution containing sodium chloride in a typical concentration of 1 % to 2 % by weight; said semi-reformed brine solution is optionally subjected to a pH adjustment step (Station 2); (II) following said optionally pH adjustment the semi-reformed brine solution is transferred to a Reverse Osmosis System (Station 3) in which an increase of NaCl concentration is accomplished, providing a reformed brine solution suitable for regenerating an ion-exchange resin applicable in water softening process; (III) Applying the reformed brine solution in regeneration of an ion-exchange resin.
