Description:TECHNICAL FIELD

The present disclosure relates to the field of water softening process, and more specifically, to a method and a system of regenerating a cation-exchange resin in a water softening process.

BACKGROUND

Brine consumption in water softening or water softener regeneration process has been a primary concern for regeneration process. There have been numerous efforts to reduce and optimize brine consumption by improving regeneration efficiency of cation-exchange resin.

Various ion exchange methods are known to the skilled in the art. Most commonly, water is run through an exchange resin to adhere the hardness ions calcium and magnesium to a resin in the softener. However, when the resin becomes saturated, it is necessary to regenerate the resin using large amounts of sodium chloride dissolved in water. This regeneration process has numerous known disadvantages, namely requiring the use of briny solutions and chloride from added sodium chloride used to flush out the resin. Accordingly, when wate , Claims:WE CLAIM:

1. A method (400) of regenerating a cation-exchange resin in a water softening process, the method (400) comprising:
receiving (402) a cumulative value of water processed and a total number of operational cycles performed in a softening device;
determining (404) a regeneration condition by comparing the received cumulative value with a predefined threshold value;
initiating (406) a first regeneration sequence based on the determined regeneration condition;
receiving (408) a predefined quantity of salt into a salt chamber (222) of the softening device, to generate a brine solution by dissolving the salt in water within the salt chamber (222); and
regenerating (410) the cation-exchange resin through ion exchange in the brine solution based on contact of the brine solution with the cation-exchange resin.

2. The method (400) as claimed in claim 1, comprising:
transmitting an alert, for a user, to indicate addition of the predefined quantity of salt into the salt chamber (222) of the softening device
