Types of salt
If you are very annoyed about the stains on your dishes and sinks or you cannot handle the dull aspect of your clothes you should know that hard water may be the cause of these problems. Although you cannot get rid of hard water, you can soften it using a water softener system. Soft water will solve all these issues and will help you clean and wash very efficiently.
Water softener salt- working principles
A water softener is used to transform hard water into soft water. do you want to know how can it do that? Let us see! The hardness of water is caused by a large amount of minerals such as calcium and magnesium in its content. Calcium and magnesium are alkaline earth metals, charged positively; they are responsible for the hardness of the water. A water softener salt eliminates these positively charged ions and replaces them with sodium or potassium ions. Thus, soft water results. There are many types of salt one can use for water softeners. Let us talk about them.
Types of salt for water softeners
The salts in water softeners eliminate calcium and magnesium along with iron ions from hard water. These salts can be divided into evaporated salt, solar salt and rock salt.
- Evaporated salt
Evaporated salt results from the underground water. This means that when the underground water dries out, the salt in its content remains. The salt is extracted using special mining machines. As the name suggests, the salt comes from the evaporated water. This is a very effective salt type because it softens the water in a very short time due to its high concentration of sodium chloride.
- Solar salt
Solar salt results from the sea water, which is trapped into a certain area of the shore to help it evaporate. After the water evaporates, the salt in is content remains behind. This salt is then collected and sold in a powdered form or in pellets. Solar salt does not have as much sodium chloride in its content as evaporated salt and it is not that soluble. It has a medium efficiency.
- Rock salt
Although it is very cheap, rock salt the least effective type of all. Rock salt is actually a mineral deposited into the ground. It results from the mining process. Along with the salt rock, there are also other substances that are very hard to eliminate. This is why this type of salt is not very soluble and does not soften hard water efficiently enough. This is not very suitable to use for water softener systems.
You can use these salt types for water softener systems. Although evaporated salt is the most expensive of all, it is the most efficient and you will have a high-quality soft water. There are cases when evaporated salt can be mixed with solar salt. Keep in mind that rock salt cannot be combined with any other salt type.
