What is a solar salt water softener? If you have installed a water softener in your home, you probably know that it uses different types of salts.
An example of a salt used to clean a fabric softener is solar salt. From the word sun, you may already have an idea of ​​how it is made.
Let's see if you're right. Let's find out what a sun softener is and how it is used.


What is solar salt?

Solar salt is mainly produced using solar energy. It comes from seawater, which evaporates under the influence of the sun.
Solar salt is a small white opaque crystal.

How is solar salt produced?

The solar salt production process uses natural evaporation and precipitation. This is the oldest and most environmentally friendly method of salt production.

First, salt water is harvested from natural bodies of water such as lakes, oceans, rivers and groundwater. These waters are channeled into a series of shallow, interconnected lakes.
The water slowly evaporates as it flows through the lakes due to exposure to the sun and wind. When the water evaporates, sodium and chlorine remain. They bond together and form salt.
The water that reaches the last lake is highly concentrated. The salt then crystallizes into brine (salt and water solution).

The salt crystals are cleaned, washed and dried to remove impurities. They are stored in a stack awaiting examination.

Magnets and metal detectors are also used to remove unwanted minerals from salt.
The crystals are crushed to different levels of fineness. Food-approved solar salt will have a finer consistency, whilesoftenerThe solar salt becomes coarser or pressed into pieces.

Salt contains 60% chloride and 40% sodium. The purity of the salt will depend on the amount of sodium chloride concentration.
Table salt has a higher concentration which is 97% and above.

How does salt help soften water?

When you think about the water softening process, it can be a bit confusing.
If you get salt in the tank, does that mean you are using salt water? But tap water is not salty. How is it done?

Do not worry. There is a simple explanation.

Salt consists of two elements, namely sodium (Na) and chlorine (Cl).
In general, a water softener does not add salt to the water. It breaks the bond between sodium and chloride and uses only sodium.

But why only sodium? To answer this question, we need to understand how a water softener works.
A softener is mainly used to remove minerals such as magnesium and calcium from hard water.
The system uses a process called ion exchange.

The water softener has a resin layer consisting of resin beads. These spheres are negatively charged sodium.
The metals in water are positively charged. Since they are opposites, the positively charged minerals stick to the resin beads. Purifies the water.

Once the resin is filled with minerals, it must be regenerated. This is where salt comes into play.
Salt is added to the brine tank, where it is mixed with water. The sodium, which has a positive charge, separates from the chloride and binds to the (negatively charged) resin.

As the salt water flows through the resin, the metals in the resin are separated. Minerals are washed out of the reservoir.

This leaves the resin with positively charged sodium ions. If you use hard water, another ion exchange takes place. But this time it is the sodium ions that separate and mix with the water.
So no, a water softener does not make water salty. It only adds sodium ions.

Now you don't have to worry about the sodium content. Drinking water is perfectly safe as long as sodium levels are within the normal range.

Our bodies naturally need sodium to function. It helps nerves and muscles to function better.
But sodium poses a risk to some people, even in small amounts. If you have any of these, consider installing a water softener:

  • Cardiovascular disease
  • High blood pressure
  • Low sodium diet
  • Kidney and gallbladder diseases

Reasons to use solar salt as a fabric softener

There are three reasons for using solar salt in water softeners.
Solar salt has a high level of purity. The most available solar water softening salt on the market is 99.6% pure. This means that solar salt dissolves faster and has almost no impurities. This makes them more efficient.

Unlike rock salt, solar salt does not contain shale particles that can clog the water softening system.
Solar salt is also subjected to a mineral separation process, which consists in the use of magnets. Make it free of metals that can be harmful to humans when mixed with drinking and cooking water.

In addition, solar salt is a cheap alternative. Although evaporated salt is the highest salt and is the most effective, it is expensive. Solsalt can do the job satisfactorily at a lower price.

Other types of salt

  • Rock salt- Salt comes from a salt mine. It forms naturally over hundreds of years.
    It is harvested with seed drills and large machines.
    Salt does not necessarily have to be a large piece of rock. It can look like veins like coal.
    Most of the processes take place inside the salt mine.
    After the salt is extracted from the mine, it is examined and separated. Packaging will depend on the texture and size of the crystals.
    Rock salt contains slate and other rock particles. They can cause problems with the softening system.
    Particles can clog the diesel particulate filter weld, the resin bed and even the supply pipes. It can destroy the entire system.
  • evaporated salt– Evaporated salt is the purest form of salt. Like solar salt, it is formed by evaporation.
    However, unlike solar salt, evaporated salt goes through a process where the steam separates the salt from the water.
    The evaporation method begins with drilling a well in the ground. The depth may vary from a hundred to a thousand feet until the salt bed is reached.
    The water is then led out into the well. It flows through the salt bed and dissolves the water in its path. And it comes out of the other well as brine.
    The brine is taken from the other well and stored in large tanks.
    It is then poured into huge vacuum containers. The pots are connected.
    The first pan is heated by introducing steam into it. When it boils, the steam goes to the next pot and the process starts over. Increases energy efficiency.
    The salt obtained is very pure. Can be used in water softeners.
    It is very effective and does not cause salts and metals to build up in your system.
    But this type of salt can be expensive.

What you should know before using solar salt

Here are some things to consider when using solar salt to soften water.
Resin bearings must be reconditioned or recharged regularly. It is recommended to do this at least once every three days. Keeps the resin healthy and active.

Solsalt is high quality salt. It has fewer impurities that can damage the fabric softener.
Add the correct amount of solar salt for each regeneration. The brine tank should be a quarter full of salt.

Even though solar salt is pure, there is still the potential for it to build up in your system over time. Check containers and tubes regularly to prevent clogging.
The purity of solar salt can range from 96 to 99 and above. You can check the label if you want to ensure the quality of the salt you are using.

If using a salt block, make sure it is submerged in water. This will ensure that the salt block dissolves faster. Otherwise, recovery will take longer.
