The purity of water is an essential requirement in various uses of water. When humans drink water they need a certain degree of purity in the water they are drinking. The industrial applications of water require a whole new form of purity in the water stream. All of these facets have given rise to various ways of water filtration. In this blog post, we will discuss water purification methods that industrial processes require in order to continue processes.
Pure water is a term that we frequently hear in advertisements and it makes sense that pure water would mean drinkable water. But in fact, pure water is a professional term that is used in industrial water processes. The term pure water means water that is not mixed with any other chemicals and has the exact pH of 7.
The reason it is hard to find pure water is that water is the most soluble liquid in the world. The water molecules mix with everything they come in contact with and absorb the chemical composition of the incoming material. This leads to a situation where the chemical composition of the water continuously changes. Now, if you want to retain the purity of water, it has to be always secured in a setting because it can even absorb gasses. Then the water will also need to be stored in a completely inert and airtight container so that the water will stay sterile and will not be contaminated by various other chemicals.
The process of water purification is complex and depends on the purity of water that is expected. The water will have a higher level of purity if it is distilled and less purity if it is boiled, etc. Here is how pure various processes make water.
Evaporation: If water is boiled completely and all the water vapours are stored in a sperate sterile container, then the water will be perfectly pure. This water will not have any form of contamination and will be pure water. This is a highly expensive way of making water pure and this water is only used in highly sophisticated chemical processes.
Boiling: Boiling is the second most reliable process of water distillation. All the germs in the water are dead and the impurities will also become solidified and clear out. The water is good for drinking and other sanitation based purposes. But it is not free from any external chemical attacks and will need to be cleaned more if the purity of water needs to be a hundred per cent.
Distillation: This is the most common form of water purification that is used in the world. The water is distilled through the gravel and it takes away all the impurity. But the germs are not killed in the process. The water is good for everyday use but it is not ideal for drinking.
These are the main processes you should know.
