The result is water with zero mineral hardness but a slight increase in sodium content. Water softeners typically contain a mineral tank filled with small resin beads. Hard water runs through the resin beads, and the sodium ions are swapped for the hardness minerals. After this ion exchange process, the water leaving the softener system is soft.

The size of your softener, measured in grains, determines its capacity to remove hardness minerals before requiring regeneration, directly impacting salt usage frequency. While a general rule suggests that a softener uses approximately 15 pounds of salt per 1,000 gallons of water treated for each grain of hardness removed, this is just an estimate.

Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of …
