One treatment more effective water and used at home and industry is the softening of hard water. This substance is common in places that obtained from wells, and cause a great deterioration of the pipes, faucets, and any element that comes into contact with it.

Hard water treatment is done through softeners, some artifacts are eliminated with the minerality of this type of substance. They include magnesium, calcium, and in some cases, iron. These three elements have a positive ionic charge, which generate the problems stipulated above.

The operation of this kind of equipment for hard water treatment is simple. The device collects hardness minerals generated, which are undergoing a process of solution from certain reagents, the most common being sodium.

There are different types of reagents that can be used for this type of water treatment, especially the salts. Currently, three species can be achieved to add salt softeners: evaporated salt, rock salt and solar salt.

Evaporated salt is one that is obtained from various processes of mining in the underground reservoirs where there is this type of ore. From them, the salt is dissolved and energy using gas or coal, moisture evaporates. The evaporated salt contains sodium chloride by 99.9 percent.

Rock salt is created naturally in the earth and it can be found in underground mining sites, and has between 98 and 99 percent sodium chloride. Moreover, solar salt is one that is obtained through the evaporation of salty water from the sea, and has sodium chloride by 85 percent.

Although the types of salts produced similar effects at the time of softening the water, there are differences between them.

Rock salt is the cheapest, but softeners that use this type of item require more regular cleaning, as this has a significant percentage of matter insoluble in water. In relation to the other two, evaporated salt is one that has less material of this type.

You can also note that most softeners admit the possibility of using multiple types of salts, though some are designed for any particular.
