Different Ways to Purify Drinking Water

Drinking pure and safe drinking water is the utmost need of every human being to stay healthy. The water we drink is being polluted with many dangerous impurities that make it highly unfit for consumption. The water we get from nature becomes polluted by various facts but the primary cause of water pollution is humans. We all are contributing to the degradation of our natural resources. We have contaminated our water sources so badly that today, we have come to a situation where it has become impossible to find pure drinking water. The level of water pollution has come to such a condition that it would be impossible to find any source of water that has been not affected by the contaminants.

To fulfill the need of pure drinking water for domestic, industrial and commercial purposes different methods of purification of water are developed in order to purify, treat water contamination. The methods of water purification differ according to the pollution level, and type of contaminants that are present in that water.

Different Methods of Purification of  Water

Even if the water looks clean, it may contain impurities that are not visible to us. In fact, in chemical sense water cannot be pure, therefore, some purification technology must be introduced to purify the drinking water. Here are some of the most common methods of water purification:


Boiling water - methods of purification of water 

Boiling is oldest and the simplest purification technique used to kill microorganisms present in drinking water. All you need to do is heat the water over a gas burner till it starts boiling. The taste of the water becomes flat as boiling water removes oxygen from the drinking water. Boiling, however, doesn’t remove chemicals and heavy metals from the water. Nowadays, these impurities are most commonly found in drinking water that cannot be removed by just bubbling the water.

Sediment Filtration

Sediment Filtration - methods of water purification 

The method of purification is helpful in removing physically suspended particles such as sediments, particulate, or turbidity. In this process, sediment filters trap and remove the suspended particles from drinking water. The sediment filters act as a net that traps all the physical impurities present. This process is only suitable if the water contains physical impurities. Sedimentation process, however, does not improve the taste and smell of the water as it does not remove the chemicals and metals.

Carbon Filtration

Carbon filters used for purification of drinking water 

Carbon is one of the purification methods that has been used for a long period. Carbon filtration is one of the very good methods of water purification used for removing chlorine and other impurities from the drinking water. Activated carbon filters are used in the purification of drinking water. In this process water is allowed to pass through different forms of activated carbon, the activated carbon absorbs the impurities and makes the drinking water pure and safe. The activated carbon is mostly used in two forms solid and granular. The solid form of activated carbon is mostly not used as it takes more time. However, it is one of the best ways to purify water because if the water passes through the carbon slowly, more impurities will be absorbed by the carbon.

Ultraviolet Technology

UV purification - ways to purify water 

Ultraviolet purification is a water purification method that uses the ultraviolet light of a short wavelength to kill all microorganisms in the drinking water. Water is passed through the UV rays which make all the microorganism in drinking water inactive. It is considered as the best purification method to kill the microorganisms that can cause many water borne diseases and provide safe and bacteria free drinking water.


Distillation - methods of purifying water 

Distillation is one of best water purification process to give pure drinking water which is free from every impurity. However, this technique utilizes a huge amount of fuel to boil and vaporize the water. This requires boiling of water in an enclosed container where water is boiled until it reaches its boiling point and begins to evaporate. The temperature is kept constant to ensure continuous evaporation of water. With the help of a hose or any other transportation device, the evaporated water is collected in another container. The process of distillation is highly effective but it is also a very much complicated way of purifying water.

Reverse Osmosis

Reverse Osmosis process is by far the best purification process that gives pure drinking water. Since water pollution is now at an extreme level, many chemicals and heavy metals can enter into the water making it harmful to consume. Reverse Osmosis in such situation is the best way to remove all the chemicals and metals from the drinking water and makes water pure and safe. In reverse osmosis, a semi-permeable membrane is used which has extremely small pores so that no impurities can enter through it. Water is passed through the membrane by applying a pressure greater than the osmotic pressure to filter our all the contaminants and thus provide pure and safe drinking water.

Water purification is necessary to make the water ideal for drinking to stay healthy. Therefore it is highly imperative that you use a water purifier in your home. You can choose the suitable water purification process according to the level of contaminants present in your water supply. So, get your water tested and choose the best water purifier wisely.
