How Water is Purified at Balara Water Treatment Plant

The Balara Water Treatment Plant is one of the largest water treatment facilities in the Philippines. It is responsible for providing clean drinking water to millions of residents in Metro Manila. In this article, we will explore the process of how water is purified at the Balara Water Treatment Plant.

Coagulation and Flocculation

The first step in water purification is coagulation and flocculation. Chemicals are added to the water to form tiny particles called flocs. The flocs attract dirt and other impurities in the water, which causes them to clump together and become heavier. These impurities then settle at the bottom of the treatment tank.

Sedimentation and Clarification

After coagulation and flocculation, the water is allowed to settle in a sedimentation tank. The heavy impurities that have settled to the bottom of the tank are removed, leaving the clearer water on top. This process is known as sedimentation and clarification. The water that has been clarified is then sent to the next stage of the purification process.

Filtration

Once the water has been clarified, it is sent through a large filter to remove any remaining impurities. The filter uses materials such as sand, gravel, and activated carbon to remove any particles, chemicals, and bacteria that might still be present in the water.

Disinfection

The final stage in water purification is disinfection. This process kills any remaining bacteria, viruses, and other microorganisms that might be in the water. Chlorine is the most commonly used disinfectant in water treatment plants. A carefully measured amount of chlorine is added to the water to ensure that it is safe to drink.

Conclusion

The process of purifying water at the Balara Water Treatment Plant is complex and requires the expertise of trained professionals. The water that goes through this process is safe to drink and helps to prevent the spread of waterborne diseases. As individuals, we can help to conserve water by being mindful of our usage and by properly disposing of chemicals and other pollutants that can harm the environment and our water sources.
