How Water Filtration Plant Works

Water filtration is the process of removing impurities and contaminants from water to make it safe for consumption or other purposes. Water filtration plants are used to treat the water supply for cities, towns, and other municipalities. In this article, we will explore the process of how water filtration plants work.

Coagulation and Flocculation

The first step in the water filtration process is coagulation and flocculation. This step involves adding chemicals such as alum and polymer to the water. These chemicals cause impurities and small particles to stick together and form larger particles called floc. The floc can then be easily removed in the subsequent steps of the filtration process.

Sedimentation

The next step in the water filtration process is sedimentation. During this step, the water is allowed to sit in a tank or basin for a period of time. As the floc settles to the bottom of the tank, the water above becomes clearer. The clarified water is then removed and sent to the next step in the process.

Filtration

Filtration is the third step in the water filtration process. During this step, the water is passed through a filter comprised of sand, gravel, and other materials such as activated carbon. The filter removes any remaining fine particles and impurities in the water, resulting in clearer and cleaner water.

Disinfection

The final step in the water filtration process is disinfection. This step involves adding a disinfectant such as chlorine or ozone to the water. The disinfectant kills any remaining bacteria, viruses, or other microorganisms in the water, making it safe for consumption.

Conclusion

Water filtration plants are essential in providing safe and clean drinking water for our communities. The process involves coagulation and flocculation, sedimentation, filtration, and disinfection. By understanding the water filtration process, we can appreciate the efforts of those who work hard to ensure the quality of our water supply.
