25 Great Ways How to Purify Water for Drinking

The water that we get is not the purest form of water when it comes to drinking. There are so many ways that we can use to purify our water. Let’s have a look at 25 Great Ways for purifying water for drinking.

1. Boiling Water

One of the best and tested techniques to purify the water for drinking is by boiling it. Boiling water at a high level helps in killing all the harmful microorganisms in the water that might be contaminating it. It is one of the oldest techniques that is still continued in various households to make sure that all the contaminants in the water like bacteria, virus, parasite and many other microorganisms are eliminated during the process and hence sanitizes the water.

2. Ozonation

One of the most popular and also an FDA approved method to purify the drinking water is known as ozonation. This process is known to be very effective due to the presence of a great component O3 which is also known as ozone.It is a very powerful oxidant that has properties that can inactivate fungi, pesticides and can contaminate viruses in the best way possible. Ozone is a great disinfectant that has the capability of oxidizing various metals that further help in aiding the process of filtration of the drinking water.

3. Ultraviolet Germicidal Irradiation

Ultraviolet Germicidal Irradiation is a technique that is used for eliminating and inactivating the contaminating microorganisms for purifying drinking water. This technique consists of setting drinking water at appropriately short wavelength so that the contaminants in the water are eradicated which in turns enables the purification of drinking water. The water that has undergone this process of filtration and purification is known to be the healthiest water for consumption. However, this water must not be exposed in the visible light of the sun.

4. Water Chlorination

One of the most common methods of purifying drinking water is known as water chlorination. The drinking water can be quickly made safe for drinking by the addition of 5 to 6 percent household chlorine bleach in the water. Some of these chlorine bleaches might contain certain perfumes and dyes which should not be used while purifying the water. Also, one thing must be noted that the household chlorine bleach has an expiration date and hence must be extra careful about the date before using this technique of water purification.

5. Iodine Treatment

Whenever clean water is needed for drinking or brushing your teeth in an emergency, iodine treatment of water is a technique that comes to the rescue. It is one of the most common and advised techniques of water purification especially when you are camping or are somewhere in a place where you do not have access to clean water. Iodine treatment is a very effective method when it comes to eliminating toxins and contaminants from the water.

6. Solar Disinfection

Solar disinfection is one of the greatest methods to drinking safe water. It is a scientifically proven technique that is known for the reduction of bacteria, virus, protozoa and other diarrheal disease incidence in the drinking water. It is a cost-effective method that can easily decontaminate the drinking water. After using this water purification technique there is very less change noticed in the taste and the consistency of water which is great because some other methods tend to change the taste of the drinking water as well as it consistency.

7. Reverse Osmosis

By pushing the drinking water through a semi permeable membrane, the water can be free from various contaminants and can be fit and safe for drinking. This method is known as reverse osmosis. This process is extensively used for water purification. By performing the process of reverse osmosis, the drinking water gets dematerialized and deionized. It is capable of removing a large amount of colloids, dissolved salts (ions),organics, particles, bacteria and pyrogens from the water employed for drinking that makes it safe for consumption.

8. Solar Distillation

Solar distillation is a process of decontaminating water by processing drinking water in the heat of the sun. It is one of the simplest procedures when it comes to water purification. The simplest method of separating water from salt and other dust particles is through evaporation. So, when the temperature is high, the water evaporates into water molecules leaving behind all the impurities. Then the further process of collecting the pure water is done is by condensing the water. It is done when the vapors convert into liquid when they are put back into the normal temperature.

9. Filtration through Cloth

Filtering water by putting it through a piece of cloth is one of the simplest methods of water filtration and it is sort of a do it yourself type of technique. One of thing to be noted is that with this method, one cannot separate the contaminants and micro organisms from the drinking water. Filtering the drinking water through cloth allows you to get rid of the big dirt and mud particles and separate them from the drinking water.

10. Filtration through Winnowing Sieve

Filtration is one of the most common methods for filtering water and is done by using various different types of items in the form of filters. One of the other techniques for filtration is done through a winnowing sieve. Whenever the drinking water is contaminated by items caused by the wind like dry leaves and mud, the most go to technique for purifying the water is by filtering it through a winnowing sieve. However, this is not a useful method when the water has many big contaminants that can pass througha winnowing sieve.

11. Clarification and Filtration through Plant Material

Using plants for the purification of water has been used in many countries from a very long period of time.An entire plant as well as plant materials such as seeds, beans and many more has been used a large number of times to clarify and filter the drinking water and make it fit for consumption.This technique follows three main procedures of physical, adsorption, and absorption. It is known to filter out more than 70 per cent of the contaminants from the drinking water.

12. Filtration through Clay Vessels

This is one of the most common techniques of filtering water which is still used in a lot of households in many countries. A clay filter is well known to convert contaminated water into fresh water in a less time and also in a very cost-effective manner. These clay filters can clarify and purify almost four liters of drinking water within an hour. It is a very effective and also the only method of filtering drinking water in many backward countries.

13. Jempeng Stone Filter Method

Jempeng Stone Filter Method is one of the most traditional methods of filtering drinking water that makes it fit for consumption. It is a technique that was used in many households in many countries long time back and is still prevalent in a few households today as well. This technique was invented in Bali, Indonesia and is mainly used to clarify and purify the muddy water. It is a very cost-effective method of purifying the drinking water and can treat highly turbid water as well.

14. Flocculation

It is a very common scientific method used for filtering and purifying the drinking water. It is a process that can be applied to ease various processes one of which is water treatment. Flocculation is one small process involved to kick start the big process of water treatment and purification. In order to ensure that the water is clean, pure and fit for drinking, the water treatment process involves the working of various procedures like flocculation, sedimentation, filtration and disinfection.

15. Sand Filters

Pressure sand filters are used to eliminate suspended solids and turbidity from drinking water as well as waste water in order to clarify and purify it. It is a very cost effective and efficient method and technique used to filter drinking water. The pressure sand filters can eradicate so many impurities from the drinking water. Raw water consists of many contaminants and impurities that make the water unfit for drinking. Pressure sand filters are one of the oldest and still used methods of filtering drinking water.

16. Aeration

It is a technique wherein air and water are brought into close contact for the purpose of purifying the water. This technique is used in the water treatment for three main purposes. These involve the decarbonation of water. This means that the levels of carbon dioxide are reduced from the drinking water so that it’s best for consumption. It also oxidizes the iron and magnesium in the drinking water which is very harmful to the body if consumed. This process also helps in stripping which basically means reducing the ammonia and hydrogen sulfide from the drinking water.

17. Membrane Filtration

It is one of those techniques that filter the water for drinking as well as reuse purposes. This technique of water filtration has been used from a very long period of time for the purpose of purifying water as well as wastewater. It is a comparatively expensive method of cleaning and purifying and hence is used in a few sectors only. It is not a very common technique and its applications are mainly used for reusing drinking water and sometimes for filtering water for drinking and consumption purposes.

18. Sedimentation

It is one of the most common techniques used for filtering water from the suspended solids from the water. It is done by the use of gravity. It is a primary method of filtration used for the treatment of sewage in removal of floating solids from drinking water. Tanks known as clarifies follow this method of purifying water wherein all the solids are removed from the drinking water in order to cleanse it for the purpose of consumption.

19. Direct Contact Membrane Distillation
