Cleanliness of daily drinking water is very important, in which it is necessary to ensure that the water is not contaminated with disease-causing bacteria. Unfortunately, wherever you live, pathogens can easily be found in water sources (including river water, spring water, lake water, and groundwater).

Below, we will take a closer look at water disinfection methods, and Scimitar will introduce you to the 5 best, most popular water disinfection methods.

Why should you disinfect drinking water?
Pathogens are responsible for a wide range of waterborne infections, easily causing gastrointestinal problems that can eventually lead to serious complications and even death. home pure water purifier in bangladesh

Without proper water disinfection, pathogens such as Campylobacter, Salmonella, Giardia, Shigella, Pseudomonas, Norovirus, Legionella, Cryptosporidium and a long list of other dangerous contaminants can remain in your drinking water.

But when exactly should you disinfect your water? Here is a list of the most common scenarios:

You are planning to use your drinking water supply not from a local water source (such as pond/lake/river/stream, well water or rainwater)
Water supply is interrupted due to natural disaster (earthquake, flood, etc.)
Tests were performed and the results showed the presence of coliform bacteria in the stool (eg E. Coli )
You or a member of your family has a weakened immune system
You are in areas with water safety issues

Drinking water needs to be disinfected to remove pathogenic bacteria and viruses in the water
Things you should pay attention to before choosing a water disinfection method
Here are the most important things that you should not overlook if you are aiming for the ideal water disinfection method:

Make sure the water disinfection method you choose kills viruses, bacteria, cysts, and other dangerous pathogens that may be present in your water.
The success of your chosen water disinfection method cannot be affected by fluctuations in the composition of your water.
Disinfection must take place in a short period of time, and ensure that a large number of pathogens are destroyed.
The selected water disinfection method must work regardless of the temperature of the water.
Instruments for sterilization should be safe and easy to use.
Make sure that disinfection does not adversely affect the quality of your water (e.g. make it toxic or unpalatable)
Water disinfection methods, where disinfectants are used, should be readily available to calculate the disinfectant concentration.
Methods of water disinfection?
There are many ways to disinfect water, with or without chemicals. Here are the 5 most common water disinfection methods.

See the article Drinking water treatment methods .

1. Boil
One of the simplest and oldest ways to disinfect water is to boil it. You can boil water for 1 to 5 minutes, depending on the type of pathogens you want to get rid of. This popular method has been used for a long time to remove bacteria and viruses from water, even for water suppliers.

However, boiling water cannot solve all pollution problems. If your water is contaminated with heavy metals or chemicals, boiling will not be the right disinfection method. In this case, you can install a professional water filtration system to filter heavy metals, chemical impurities and bacteria and viruses in the water.

2. Disinfect with chlorine
Along with boiling, chlorination is a common water disinfection method that removes harmful contaminants from water. This water disinfection method is widely used by water suppliers around the world.

By chlorination, pathogenic bacteria can be effectively eliminated, ensuring every household has a safe source of purified water.

However, chlorination also has disadvantages such as unpleasant odors or can cause skin problems such as eczema, respiratory problems such as asthma, hair problems or even Even more serious diseases like cancer are caused by the amount of chlorine and by-products remaining in the water after the disinfection process.

3. Water filter (water purifier, water purification system)
Nano filtration system ( Aragon core, Nano Silver core), UF (semi-permeable/capillary membrane), RO (reverse osmosis membrane) helps to remove bacteria and viruses from water very well and reliably. These systems also remove many other pollutants (organic substances, heavy metals, etc.) from the water and at the same time improve the taste of drinking water.

The excellent filtration capacity and versatility and ease of use of water purifiers/water filtration systems make them more and more trusted and chosen.

4. UV sterilization
Using UV water purification to disinfect water is another great way to protect your health from water-borne diseases.

Ultraviolet light has the ability to remove bacteria and viruses quickly, effectively >99%. The only thing you need to be aware of is that if the water has a lot of sediment, you need to filter it first because the residue can block UV rays and can affect the effectiveness of the disinfection process.

Water purification systems using ultraviolet rays do not change the physical and chemical properties of the water, do not change the taste of the water and do not create by-products or create any side effects.

5. Ozone sterilization
Ozone (O3) in water is an unstable molecule, produced by the combination of oxygen and UV light. Ozone disinfection provides a broad spectrum disinfection solution and ozone water disinfection produces less hazardous by-products than chlorination.
