Why to Soften Hard Water?

Hard water usually consists of huge quantities of dissolved salts and minerals in it. This water may not be suitable for domestic usage such as washing clothes, cooking, cleaning utensils etc. This usually happens as the dissolved magnesium and calcium may have adverse effects on the household appliances. This can eventually result in salt clogging in water heater equipment and pipes.

The working of detergents and soaps can get hindered due to the usage of hard water. Hard water may react with detergents and soaps and may have the ability to nullify their effect and it also forms a sticky scum. Water softeners help in lowering the mineral and salt content in hard water making it soft. Read on to know

  • Ion-exchange resins are considered as the basic water softening systems which can be used for household purpose.
  • However, many opt for electromagnetic water softening systems. Ion exchange helps in holding the sodium ions.
  • This usually happens when the water passes through the resin structure. During this , exchange of ions takes place leaving behind the sodium ions.
  • Earlier certain minerals like zeolites are used as they exhibit ion-exchanging properties.
  • A water softener plays a major role in replacing the less reactive ions with more reactive ones resulting in the formation of stable salts which will not react to other chemicals.
  • The water which leaves the resin structure after the ion exchange is soft water and can be used for household purposes.
