Your body consists of more than 70% water, which just goes to show that drinking safe water is essential for your body to function normally. However, there are issues about how safe the water that comes out of your faucet is, especially with pollution and other environmental problems that take place all over the world.



The contaminants found in water supplies are categorized into four: biological entities, heavy metals, organic metals, and inorganic metals. These contaminants can have devastating effects on our body; hence, having them reduced or removed from water supplies cannot be overemphasized. To address this need, different water purification methods are used to produce what is called purified water or pure water.



Many companies supply pure water, not only for health purposes but for industrial purposes as well. There are also companies that offer home water purification products and services. Moreover, the techniques used to purify water vary.



One common method used is carbon filtering. Carbon is known for being a powerful absorbent and it is enhanced by adding a slightly positive electrical charge to it. The product is then called activated carbon, which helps reduce or remove water contaminants, including volatile organic chemicals or VOCs, herbicides, pesticides, chlorine, radon, and other chemicals. Another common method is reverse osmosis, which filters contaminants with the use of a semi-permeable membrane. While pure water passes through the membrane, the contaminants are trapped in its tiny pores. There is also the ultraviolet (UV) water purification, where water is exposed to ultraviolet light for a certain period of time. The purpose of this is to damage the structure of the microorganisms present in the water, making them sterile.



Furthermore, when we speak of purified water, there are forms of purified water that immediately come into our minds: distilled water and deionized water. Apparently, the two are products of different methods. As the terms imply, the former is a product of distillation while the latter is a product of deionization. Distillation involves boiling water and condensing its steam while deionization involves the use of resins, which bind to and filter out mineral ions or salts from the water.



These forms of pure water are common because of their other uses besides used for drinking. Deionized water, for instance, is better known for its use in laboratories and other industries. It is used as a medium in experiments as it does not contain elements that may affect the results. It also makes good battery water as it is devoid of minerals that tend to reduce the lifespan of cell batteries. It is also used to wash cars and windows as it does not leave any water spots.



These forms of purified water are further used in steam irons for pressing clothes; they help reduce mineral build-up and increase the lifespan of the iron. Some people also use them for household aquariums as they are devoid of chemicals found in tap water.



The consumption of high quality water is no longer a luxury. There sure is a strong demand for pure water. It is important to make sure that the water you are drinking will help make you stay healthy and will not make you sick. It is also needed in certain industries and other practical uses. Of course, it is your choice whether to patronize purified water or not. Various sources of information are available, especially on the internet, and it will definitely not hurt if you keep yourself informed of water purification. More important than anything else is your health, and you would not want to put your health at risk just because you failed to keep yourself informed.
