Water Softener Plant in chennai

Hard water is frequently unsuitable for many industrial and domestic purpose. When water is referred 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.

Hassles of Hardness

Water Softening 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. As the name implies ion exchange is a process in which undesirable ions are exchanged for more desirable ions. The softening process consists of passing raw water containing hardness through a bed of cation resin in sodium form. The hardness ions Ca & Mg are taken up by resin and in exchange, the sodium ions are relinquished from the resin. This is called the service cycle, where the hard water is being softened.

Chemical Reaction During Softening Process

Ca (HCO3)2 + Na2 R = RCa + NaHCO3
CaSO4 + Na2 R = RCa + Na2SO4MgCl2 + Na2
R = RMg + NaCl

Regeneration Process

Raw water will continue to get softened till the resin gets exhausted. Bringing back the resin to it original form is called regeneration. Softener resin is regenerated by sodium chloride- Nacl (Common salt) solution. The common salt solution is kept in the regeneration tank. During the regeneration process, salt solution is injected by the ejector tube into softener. The Nacl (salt solution) replaces ca, Mg (Hardness) from the resin, the regeneration is done every day or every few days or every week depending upon the usage and design of the water softener plant.

Chemical Reaction During Regeneration Process

RCa + NaCl = RNa + CaCl2
RMg + NaCl = RNa + MgCl2
