What is simple distillation?
Author: chemical engineer
The water and energy crisis are not a newer threat to the world. Because of these water crises, the trend of using treated water is raising. The water is treated by several means including simple distillation, reverse osmosis etc. Nature has provided us the great resources of pure water, which are not only safe for human consumption, but also for the other creatures of this world. But unfortunately, because of the growing pollution rate, the environmental threats are the alarming situation for the world.

These environmental threats are also related to the safe water resources depletion, like the melting of glaciers, acid rains, river water pollution etc. Because of this depletion of natural resources of pure water, the need and demand of treated water has raised with in some past decades, in order to meet the requirements of the world's pure water needs.
Although there are numbers of water treatment technologies, including the electro-dialysis, reverse osmosis, filtration, ultra filtration, simple distillation etc, but whenever we talk about the water treatment methods, then the first technique, which comes in the minds of a common person, is the distillation. Now what is distillation? Distillation definition is simply the purification or separation method, used not only for the purification of water, but also for the separation of individual components from the very complex mixtures on the industrial large scale.
This article is about what is distillation advantage for the water purification sector, so only the distillation definition and working criteria related to the purification of water will be discussed. Although there are number of different distillation techniques, but the driving principle (or working principle) of all of them is same, i.e. purification on the basis of the difference in boiling points of the components. The home water purification by boiling the water is the most common example of the simple distillation. On industrial scale, the water is boiled up to its boiling point; once the water reaches its boiling point, it starts evaporating and vaporizing, these evaporated water vapors are collected, and condensed with condensers, to get the pure water. The remaining slurry in the distillation column (including water and impurities) is drained under the environmental protection agency (EPA) rules and regulations.
