WATER SOFTENING PLANT (Iron Remover,Sand Filters)
Hard water is frequently unsuitable for many industrial and domestic purpose. When water is referred to as 'Hard' it simply means, that it contains excess of calcium (Ca) and magnesium (Mg) Ions than normal water. Carbonate hardness is known as temporary hardness and non-carbonate hardness is known as permanent hardness. The degree of hardness of the water increases, when more calcium and magnesium ions are dissolves. These ions have their origins in limestone sediments and also from carbon dioxide which is present in all waters exposed to the atmosphere and especially in ground water. The easiest way to soft the hard water is through Ion exchange process.
Softening is the ion exchange process, it is done through resin, the most common and probably the easiest method of removing hardness (that is calcium and magnesium) from water and suitable for utility purpose.
