Water is considered hard when it gives less lather with soap/detergent/shampoo. Water becomes hard when the Calcium and Magnesium concentration increases in the water.
Hard Water is one of the most common problems faced by most of the Indians. Because hard water can cause hair loss, bald head and spoils skin & its color.
Normally hard water (bore water or some municipal water) will contain high concentration of calcium and magnesium dissolved in it.
The water that gives more lather with soap/detergent/shampoo is called Soft Water. This is the water which does not have dissolved salts like Calcium and Magnesium.
Soft Water produces more lather with little amount of soap/shampoo/detergent.
Soft Water can be obtained from natural sources like rain water, mountain river water or through natural water softening equipments like RainSoft ™ Water Softener.
A Water Softener is an apparatus which removes Calcium and Magnesium salts dissolved in water and adds sodium to give softness to water.
