Softener plant

Envirotech water softener is a unit that is used to soften water, by removing the minerals that cause the water to be hard.

When water is referred to as 'hard' this simply means, that it contains more minerals than ordinary water. These are especially the minerals calcium and magnesium. As more calcium and magnesium dissolved in the water, degree of hardness of the water increases. This is the cause of the fact that soap doesn't really dissolve in hard water. Hard water causes a higher risk of lime scale deposits systems. Due to the scale build-up, pipes are blocked and the efficiency of hot boilers and tanks is reduced. This increases the cost of water heating by about fifteen to twenty percent.

Water softening is the removal of calcium, magnesium, and certain other metal cationsin hard water. The resulting soft water is more compatible with soap and extends the lifetime of plumbing. Water softening is usually achieved using lime softening or ion-exchange resins.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.


  • Hard water reacts adversely with detergents. It means even on your little (baby) ones’ Soft towels turn rough on their soft skin.
  • Soaps and shampoos do not lather and leave you feeling unwashed. Your skin gets dry. Hard water makes hair dry and rough leads to hair loss.
  • Hard water causes residual deposit and scale builds up. Damaging your appliances such as heaters, washing machines, showers, dishwashers etc.Appliances life comes down by 45%; their maintenance cost goes up by 25%. Causes deterioration and fading of fabrics. Also reduces fabric life by 15%. 
  • Hard water leaves scales which clog pipes, faucets, valves and fixtures. Hard water reduces the cleaning power of detergents. Soft water reduces detergents requirements by about 70%.
  • Makes the food and water taste different. Cooking takes longer than ever before. Cooking gas consumption increases by 30%. Causes scale deposit on utensils.


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.

Envirotech Water softeners are solution to such problems. It serves the removal of the ions that cause the water to be hard, in most cases calcium and magnesium ions. Iron ions may also be removed during softening.
