Water Treatment Storage and Blowdown for Steam

Hardness. Water is referred to as being either 'hard' or 'soft'. Hard water contains scale-forming impurities while soft water contains little or none. The difference can easily be recognised by the effect of water on soap. Much more soap is required to make a lather with hard water than with soft water.
