Water hardness due to?
We often talk about water of different qualities in our daily life and very often we are faced with certain problems caused by hard water. The total hardness (TH) consists of all calcium (Ca) and magnesium (Mg) salts dissolved in it. Water hardness consists of two types of hardness, carbonate, and non-carbonate. Carbonate hardness consists of calcium and magnesium bicarbonates Ca(HCO3)2 and Mg(HCO3)2. Non-carbonate hardness consists of all their other salts such as chlorides, nitrates, sulfates, etc. After washing in hard water, stains from precipitated limescale remain which are very difficult to remove, textiles washed in “hard” water become stiff due to the deposition of limescale on fine textile fibers, and washing in hard water consumes more detergents due to the reaction of detergents with hardness salts and, creation of insoluble soaps – soap scum. Using soft water can solve all these problems.
