Permutit Process for Zero Hardness Water

The most efficient method to get water with zero degrees hardness is the Permutit process. This process involves the use of a special resin, known as Permutit, to remove the hardness-causing ions present in water. Let's understand the process in detail:

What is Permutit?

Permutit is a synthetic resin that has the ability to exchange ions with the ions present in water. It is a type of ion-exchange resin that is used to remove the hardness-causing ions, i.e., calcium and magnesium ions, from water.

How does the Permutit process work?

The Permutit process involves the following steps:

1. The water is passed through a column containing Permutit resin.

2. The hardness-causing ions, i.e., calcium and magnesium ions, present in the water are exchanged with the sodium ions present in the Permutit resin.

3. As a result, the hardness-causing ions get trapped in the resin, and the sodium ions are released into the water.

4. The water that comes out of the column is free from the hardness-causing ions and has zero degrees of hardness.

Advantages of the Permutit process:

1. The Permutit process is a simple and effective method for removing hardness from water.

2. It does not require any chemicals or energy to operate.

3. The process is easy to maintain, and the resin can be easily regenerated.

4. The Permutit resin has a long life, and it can be used for several years.

Disadvantages of the Permutit process:

1. The Permutit process can only remove hardness-causing ions and not other impurities present in water.

2. The process is not effective in removing dissolved solids and organic matter.

Conclusion:

The Permutit process is an efficient method for getting water with zero degrees of hardness. It is a simple and cost-effective method that can be used for domestic as well as industrial applications. However, it is important to note that the process is not effective in removing other impurities present in water, and it should be used in conjunction with other treatment methods to ensure the purity of water.
