Time Controlled Water Softening is realized by passing water containing calcium and magnesium ions, whose ion exchange causes hardness, through a cationic resin in the form of sodium.

As hard water passes through the sodium-based cationic resin, the hardness ions (Ca+2 and Mg+2) are replaced by Na+ ions bound to the resin.

The softening systems perform the regeneration processes spontaneously without any intervention on the desired day of the week at the desired time as a temporal period. The saturated resin is cleaned from calcium and magnesium ions by entering regeneration with salt water in a time-controlled manner.
