It’s better to know in advance the best water purification methods to be ready in case of troubles like war, turmoils, and other emergencies…
Waterborne diseases can be fatal. The World Health Organization confirms that about 3.4 million die every year due to impure water.
When we drink contaminated water, bacteria, viruses, and other pathogens enter our bodies. These tiny organisms are responsible for various illnesses.
Purified water no longer contains these harmful contaminants.
After going through the process of removing impurities, the water becomes potable.
There are several ways to purify water. These methods involve the use of chemicals, heat, or pressure.
The top five (5) effective means in purifying water include;
- Chlorination; and,
- Reversed osmosis.
Water Purification Method 1: Boiling
The easiest, safest, and cheapest way to purify water. This manner requires you to use a clean or disinfected container. Make sure that your container can withstand heat.
If your water appears to be cloudy or muddy, allow the particles to sit at the bottom of the container first. Filter it with a clean cloth or coffee filter before boiling.
When heating the water, you will need a thermometer to check the temperature. In case it is not available, take notice of the bubbles.
The appearance of small bubbles shows that the water is boiling.
Remember that the boiling point of water is one hundred degrees Celsius (100°C). Allow the water to boil and continue this for one to three minutes more.
After this, keep the water covered and let it cool until it is bearable to drink.
For people living in places with higher altitudes, it is best to lengthen the boiling period. Scientific studies show that water boils faster in higher places.
The longer the boiling period, the safer and cleaner your water becomes.
In general, boiling can remove bacteria, parasites, and viruses present in water.
Water Purification Method 2: Filtration
Filtration is a healthy, convenient, and portable means of purifying water. It uses both chemical and physical procedures in cleansing the water. This method reduces both large and small particles in the water. It can clean water without affecting its mineral contents. Thus, making it a healthier option.
The process utilizes chemical absorption to remove the hazardous compounds present in water. It uses activated carbon and charcoal to filter the contaminated water passes through.
Science tells us that, small particles and tiny organisms in water stick and stay in the filter. The water that comes out of the filter is clean and safe to consume. But filtration cannot kill viruses. It can only remove heavy metal particles, large parasites, and bacteria.
Water Purification Method 3: Distillation
Distillation is a process of purifying that makes use of heat to collect clean and pure water out of vapor.
Water boils ahead of all other water contaminants based on studies. When the water reaches a boiling point, it vaporizes and changes into a gas. It leaves all its contaminants and small particles as it evaporates.
Through condensation, we liquify water vapor and change it back to its liquid state. This liquid is now safe to drink.
In this process, you will be able to collect water in its cleanest state. All impurities are gone, but unfortunately, it also removes all the minerals in the water.
Distillation is an effective way to kill germs and bacteria. It also prevents the intake of salts, mercury, lead, and other hazardous contaminants.
Water Purification Method 4: Chlorination
This method of purifying water requires a thorough treatment process. Chlorination can use either liquid chlorine or chlorine tablets.
In purifying water for drinking, it is necessary to use chlorine tablets. Make sure that the water is over (21°C,) because chlorine tablets dissolve in heated water. Chlorine tablets can kill bacteria and viruses. But it is not effective against Cryptosporidium.
It is likewise effective against Giardia but you have to use it together with a filter.
Superchlorination is best in cleaning swimming pools. Here, you will have to use a huge amount of liquid chlorine to sanitize the water.
Reverse Osmosis is a water treatment that removes contaminants by using pressure. It forces water molecules to go through a membrane to filter harmful content.
This membrane is semi-permeable. It means to say that it has very tiny holes that can block small particles. It only allows smaller molecules to pass, like the size of water molecules.
It is the same with filtration, yet, applying pressure is important in reverse osmosis. Filtering and flushing out contaminants make the water clean and safe to drink.
When you use reverse osmosis, you can be sure that your water will be free from parasites or pathogens. The common contaminants removed are Giardia, Cryptosporidium, other viruses, and bacteria.
Reverse osmosis can also remove heavy metals in the water like mercury and lead. Industrialization is part of human development. As we attempt to uplift our way of living, we have made crucial sacrifices.
Our biggest mistake is when we gave up our clean water for comfort.
Our surface waters used to be clean and pristine. We had the luxury of drinking fresh, pure, and safe water with all its beneficial mineral contents.
But now, it is too late to avoid water pollution. The damage to our sources of water appears to have become grave and irreparable. Reality says purification is now the way of life. So, quench your thirst with purified water.
