Hardness leakage occurs when the resin becomes saturated and stops functioning! Is salt effective in avoiding this?
Even though a water softener is installed, hard water continues to come out. This phenomenon has a clear mechanism and prevention method. ■ What is hardness leakage? A water softener uses a material called ion exchange resin to remove hardness components (calcium and magnesium) contained in tap water to produce soft water. However, there is a limit to the amount of hardness components that this resin can absorb. Once the removal continues to a certain extent, the resin becomes saturated and stops functioning, allowing hard water to pass through unchanged. This is called hardness leakage. ■ "Regeneration" is essential to avoid it The key to prevention is the process of "regeneration," which involves regularly cleaning the resin to restore its function. Salt (sodium chloride) is used for this. Rinsing the resin with a saltwater solution of about 10 percent separates the hardness components that were attached to the resin, returning it to its original clean state. If this regeneration is not performed regularly, the benefits of soft water will not be achieved even if a water softener is installed. Ignoring hardness leakage can also lead to scale (deposits similar to limescale) in boilers and piping. The methods for regenerating a water softener and managing water quality are explained in this document. Please download the document!
