What are the Types of Water Softener Salt

You can put three different types of salts in your water softener, including blocks, crystals, and pellets. These options come in different purity levels, which will be rock salt, solar salt, and evaporated salt.

1.               Rock salt

This is the lowest quality of salt available in the market. The low quality of this salt is due to impurities, including calcium sulfate. These impurities will not let the rock salt dissolve that easily. The structure of these salts is like little rocks.

2.               Solar Salt

Solar salts have a 99.6% purity. However, these salts still have a problem softening the water if the hardness level is high. We refer to this salt as solar salt because of the manufacturing process. The manufacturing process includes evaporation of the seawater. This salt is crystal-shaped with opaque and white color.

3.               Evaporated Salt

This type of salt has the highest score when it comes to quality. The purity level of this salt is 99.9%. A common name for this variant is table salt, which is widely available throughout the world. This high-quality salt completely dissolves in water. When you mix this salt in water, you notice that there is no residue left. This confirms that this salt type is pure.

How to Calculate the Usage of the Water Softener Salt?

While calculating the usage of water softener salt, you need to consider various factors. Factors include the size of the family, hardness of the water, type of the unit, and daily water consumption. The type of unit is not part of the formula. But you need to consider it to choose the right salt product. The formula for choosing the right quantity of salt is:

A = N x H x Q

In this formula:

  • “A” is the total hardness level that needs to be removed from the system. This quantity will measure in a gram of NaCl or CaCO3. You can check the hardness level in your area through this link.
  • “N” is the number of days from the last water softener regeneration cycle.
  • “Q” is the water that flows through the system every day.
  • “H” is the hardness of the water. You will measure this amount in PPM.

After figuring out the A, you will multiply it with 0.035274. This will give the amount of salt you will require for each regeneration cycle. This amount will be in ounces.

However, it is important to consider the brand and salt type you are using. These factors will not only affect the quantity you need between regeneration cycles, but they also have a significant impact on your systems’ life.
