Water Softening: HSD Block salt is primarily used in water softeners to remove hardness minerals, such as calcium and magnesium ions, from water. Hard water can cause limescale buildup in pipes and appliances, reducing their efficiency and lifespan. Water softeners exchange the hardness minerals with sodium ions from the block salt, thus preventing limescale formation. Water softeners need salt in order to regenerate and continue to efficiently remove the minerals that cause limescale.
