How to effectively treat coliform in drinking water nowadays

Handling Coliform in Domestic Wastewater

Treatment with Sunlight

Sunlight contains ultraviolet rays. Therefore, it can naturally, simply, and easily treat coliform. The process is as follows:

Place water in bottles, containers, or bags to expose them to sunlight for an extended period. The existing ultraviolet rays will eliminate all coliform bacteria in the water.

Although this method is considered capable of removing coliform, its effectiveness is not high and it takes a long time. Therefore, coliform bacteria may still exist in the water. Additionally, the treatment volume is not high enough to meet the needs of the majority of people.

Coliform Treatment with Chlorine

Chlorine is one of the commonly used disinfectants in treating domestic water, swimming pool water.

Chlorine provides high treatment efficiency and can eliminate all coliform in the water. However, attention should be paid to the concentration and dosage according to the instructions.

According to health experts, the standard chlorine gas concentration for water disinfection ranges from 0.3 - 0.5 mg/liter of water.

Using chlorine at low doses will not completely eliminate bacteria. Excessive doses can lead to chlorine excess, chlorine poisoning affecting health such as: Immune system suppression, liver failure, kidney failure, dry skin, dry hair, skin peeling...

Coliform Treatment with RO Water Filtration System

RO water filtration membrane also has the ability to treat coliform in domestic water. This device uses advanced reverse osmosis filtration technology combined with ultra-small membrane filtration systems.

• RO water filtration systems can remove impurities, harmful substances, heavy metal ions, pesticides, sediments, and microorganisms in water, including coliform.
• RO water filtration systems provide high water treatment efficiency, safety, and cost savings. Therefore, this is a device chosen by many households and offices for use.
• The finished water after testing meets QCVN 6-1:2010/BYT - National Technical Regulation and Standard on Natural Mineral Water and Bottled Drinking Water Quality QCVN 01:2009/BYT.

Using Ultraviolet Light

Ultraviolet light has extremely high bacteria-killing capabilities. Therefore, to remove coliform, you can use ultraviolet light.

UV Ultraviolet Light can kill bacteria in water, including coliform. During the application process, attention should be paid to the following issues:

1. Ensure sufficient exposure time for microorganisms to be completely killed by the light.
2. To achieve high coliform treatment efficiency in domestic water using ultraviolet light, ensure water clarity. The cloudier the water, the lower the light's effectiveness.
3. This method is suitable for large-capacity domestic water treatment systems.

Using Water Filtration Systems

Domestic water filtration systems are also considered an effective and easy-to-implement method for coliform treatment nowadays.

In a system, there are many different filtration layers. For example, coarse filtration, carbon filtration, reverse osmosis filtration, ultraviolet light exposure. Thanks to that, all contaminants in the water, especially coliform bacteria, will be eliminated.

Benefits of Coliform Treatment

Treating coliform in domestic water has many benefits, including:

1. Health Protection

Coliform is a type of bacteria that can cause gastrointestinal infections, such as diarrhea and enteritis. Treating coliform in water helps reduce the risk of contracting diseases related to this bacteria.

2. Ensuring Water Quality

Treating coliform in water ensures that the water is clean and safe for use in daily activities such as drinking, cooking, and bathing.

3. Cost Reduction

Treating coliform-free water improves water quality, reducing costs for equipment replacement and other expenses related to using contaminated water.

4. Environmental Protection

Treating coliform in water helps reduce environmental pollution caused by discharging contaminated water, protecting water sources and the natural environment.

Therefore, treating coliform in domestic water is crucial to ensure community health and environmental protection.
