Does Home Water Purification Technology Cover All The Current Methods of Water Purification?

Since you are now convinced of the importance of having a water purification system, the most logical question that you might ask is: what water purification technology is used by these sorts of systems? It is very important to know the methods of water purification, since you will have to choose from a large variety of water purification systems.

Therefore, we may start by saying that there are three types of technologies presently used in order to purify water: the physical water purification, the chemical water purification and the biological water purification. In the next few paragraphs we will present each of every water purification technology, so that you will know what water purification system to choose.

The physical water purification is one of the first methods of water purification known to men. It consists in filtration techniques (basically, the liquid flows through a filter that stops suspended solid particles) that remove solids from water. These solid objects can vary in size, from large ones to smaller ones with the smallest particles being as big as 0,001 microns. This water purification technology is the main method of filtering liquids, since it can stop from 90 to 99% of the particles suspended in water. Therefore it is also the most important of the methods.

Another way of purifying liquids is the chemical purification. The chemical methods of water purification are used when the liquid is contaminated with solutions that cannot be filtrated by first type of filter. There are many chemical methods of purifying a liquid, varying from the use of oxidizing agents (in order to counteract reducing agents) to the use of chlorine (used for disinfection).

Distillation is yet another water purification technology that is based on the use of chemical reactions, the liquid is boiled into a special evaporation unit; the purified water is transformed into vapors that condensate into a different recipient; since the contaminants cannot vaporize, they will remain into the first special evaporation unit.

The last of the purification methods is the biological one. Since the first two did almost the entire job, the last of the methods of water purification has to reduce to nothing the number of solid (and mainly organic) particles in the liquid. This procedure implies the use of short-lived bacteria that feed on the residues from the water. After their death, these bacteria solidify and drop at the bottom of the water.

As we have said, these are the main methods of water purification. However, one water purification technology relies on the other one. That means that, in order to drink the most clear and healthy water, a water purification system must rely on all of these three methods of water purification.

Each of these purification technologies must be used together, in a certain sequence (which is: first, the physical water purification; second, the chemical water purification; third, the biological water purification). When combined, these three ways of purifying a liquid can produce water that is free of any contamination.
