Types of Water Purification Methods

Water is acknowledged as a fundamental necessity of life due to the fact that we need water to survive and we additionally use water for such purposes as drinking, bathing, washing dishes, and clothes, etc. Consequently, since water is significant to our well-being, we now have to make certain that it’s protected by taking steps to make sure it is void of impurities that can be harmful to our health. Sadly, lately, there have been studies which have revealed that most water sources are in fact contaminated with such pollutants as parasites, heavy metals, chemicals, bacteria, viruses, and other microorganisms. As well, the chemicals used to cleanse community water comparable to chlorine are unsafe to health and the water does not taste good.


Water is a source of life and we cannot do without it. Water though has impurities that make water unfit for human consumption. We cannot live without water but the water we take has to be clean before we take it or use domestically.

Making water clean is what we call water purification. Water can be purified in different ways the first method is through the water filter cartridges. These are used for commercial and also industrial purposes for purifying water. They contain a substance that eliminates bacteria and oily substances in water. Cartridges need to be changed regularly and also should be replaced to avoid overuse. They remove all the chemicals in water.

For domestic uses such as washing clothes, water softeners are normally used. They are readily found in all stores near you. Normally water from boreholes is ‘hard’ it can be softened using water softeners which are found in the liquid and solid form. Washing clothes can be tough using hard water but when the water is softened the work is eased. Bottled water is believed to be the best drinking water since it undergoes a series of purification stages that make it safe. One is because some of the bottled water is derived from springs and oasis which are a natural source of water.

Reverse osmosis

Reverse Osmosis is one of the best methods of softening. Deionization is one of the most important components of an RO water purifier. It is often used in combination with other methods like carbon absorption and reverse osmosis. osmosis water filter is another method of water purification that removes sodium components from drinking water though it provides 99% freedom of unwanted substances found in well and tap water. Doctors have recommended such kind of water. It is a more sophisticated and complicated way of purifying water since it takes a long time though it is more effective than other purifying methods.

Shower filter

A shower filter is another kind of water purification method. It ensures that water is safe for your skin and hair. Dirty untreated water may cause effects on our skins but the shower filter eliminates all the chlorine from the water and uses less plastic material than other filtration systems. Good tasting water can be done mostly by using water purifiers and filters which have alkaline ions that alter the acidic and lead contents in water.


This is one of the commonest processor technology for filtration of that. It is also one of the oldest methods that are used for making water drinkable. In this method, the water is boiled at a higher temperature. The vapor from that rises to a condenser where the vapor is condensed and collected in liquid form. Most of the impurities stay behind in the vessel being used for boiling the water and the purest form of water is obtained by condensing the vapor. It is one of the best methods of filtration of that. However, organics such as pesticides and herbicides cannot be removed from the water using this technique of distillation if the water is boiled at a temperature less than 100-degree centigrade. Distillation of water is a slow technique. Distilled water is often acidic in nature and often the vital nutrients and minerals are missing in it. It lacks oxygen and has a flat taste. Distilled water is used more for industrial use than for drinking at home.

Ion Exchange Technology

in this technology, the water is percolated through resin materials spherical in shape. These beads are actually ion exchange resins. In this method, the ions in the water are exchanged with ions in these spherical resin beads. There are two common methods in the ion exchange technology – deionization and softening.

Carbon absorption technology

Carbon absorption is the technology that is used for home filtration units. This method of filtering that can help to remove disagreeable taste and unwanted odors from that. An excess amount of Chlorine can also be removed using this method. Before buying a filter with the carbon absorption technology, you must make it a point to check whether the filtration unit is certified for the safe and effective removal of impurities like cysts, asbestos, lead, and coliform. There are two main types of carbon filtration system – the solid block carbon and granular activated carbon.

Ultraviolet Radiation

The technology uses the ultraviolet radiation for removing germs from the water. Almost all types of germs can be removed from the water using this technology. There are filtration units that use ultraviolet radiation of different wavelengths for achieving maximum purity of that.


Most people trust tapped waters much that they drink it without purifying it. It is important to know that boiling water to drink does not make our water 100% clean. Disease such as diarrhea and typhoid can be caused by drinking untreated water. Prevention is better than cure so it is better to install these purifiers in our homes and spend less on water-related diseases.
