Descaling is the removal of limescale for industrial and domestic water users in hard water areas.
What is hard water?
It’s a water that has high calcium or magnesium ions content (>≈ 1.2 mM ) acquired during its passage through calcium or magnesium-containing rock such as limestone or chalk. The amount of dissolved calcium and magnesium in water determines its “hardness”, expressed as the equivalent amount of calcium carbonate in parts per million.
The contact of Hard Water with the internal make-up of certain equipment can create limescale, calcium, rust, mud and water scale buildup.
