It is a process of water softening, and it involves heating the water that it to be softened. After that, the vapour rise to the condenser and then the water condenses and all the unwanted elements remain in the condenser tube. For instance, when hard water is being heated the remains which are calcium and magnesium will remain as particles in the condenser tube. However, there are cases where some particles intended to be separated from the water are not separated, and instead, they are found to be concentrated in the water. Such elements include herbicides. In matters concerning water softening, distillation cannot be highly reliable because it is not done in large scale and also some of the particles intended for separation may end up being consecrated in the water.
Advantages of Distillation
It is an efficient method of water softening for smaller purposes.
It is relatively cheap.
It can also be reused.
Disadvantages of Distillation
Some of the unwanted elements may be found in the distilled water. Unfortunately, liquids such as herbicides which have a boiling point of 100% which is equal to that of water will tend to condense with water and therefore, separation of this two can be tough.
As a process of water softening, distillation requires a keen eye, so that unwanted elements do not mix with water.
When distillation is done on a larger scale, a very high amount of energy needed.
The distilled water does not contain any oxygen and is also very tasteless.
It has very high levels of acidity.
Distillation should not be considered as a method of water softening because one might end up having unwanted elements in the distilled water. For example, liquids that have a boiling point equal to water will not be separated but will condense with the water. Moreover; the process requires a lot of energy to be carried out.
