Treatment method of the water hardness is too high

We can use softened water equipment, water softener for processing, water softener using ion exchange resin to exchange, regenerated by salt water, the resin to form sodium resin, namely can exchange the calcium and magnesium ions in the water, then after backwashing and regeneration, the resin with exchange ability again after backwashing, repeated use, so will the calcium and magnesium ions in the water separated from the water, reducing the hardness in the water, to soften water into the water.
