Ion Exchange Water Softening

The ion exchange water softener is one of the most common tools of water treatment. Its function is to remove scale-forming calcium and magnesium ions from hard water. In many cases soluble iron (ferrous) can also be removed with softeners. A standard water softener has four major components: a resin tank, resin, a brine tank and a valve or controller.

The softener resin tank contains the treated ion exchange resin - small beads of polystyrene. The resin beads initially adsorb sodium ions during regeneration. The resin has a greater affinity for multi-valent ions such as calcium and magnesium than it does for sodium. Thus, when the hard water containing the Calcium and Magnesium Ions is passed through the resin bed, the calcium and magnesium ions adhere to the resin, releasing the sodium ions until equilibrium is reached. The water softener has exchanged its sodium ions for the calcium and magnesium ions in the water.

What is water softener?

Water softener is such kind of water treatment plant that can reduce water hardness and make it soft for human daily life consumption.

Why we need a water softener?

Because if the water we are using is hard, it will cause great problems for human healthy, so we need a softener to help us to live safe and healthy.

In what kind of situation should we adopt a water softener?

When the water we are using has some white suspended items when boiled, or there is some scale on the surface of cup when placed for some time,that shows the water is hard. We need a water softener to reduce it’s hardness and make it healthy for human consumption.
