This blog will delve into the intricacies of the water filtration system in this area and provide insights into the maintenance costs of RO water purifiers in Delhi.

The Water Filtration Process

1. Source Water Collection

The water filtration process begins with the collection of water from natural sources, such as rivers, lakes, or underground aquifers. In Delhi, the primary sources are the Yamuna River and various reservoirs. This raw water often contains various impurities, including sediments, bacteria, and harmful chemicals.

2. Coagulation and Flocculation

Once the water reaches the treatment plant, it undergoes coagulation and flocculation. In this step, chemicals known as coagulants (like alum) are added to the water. These chemicals cause tiny particles and contaminants to clump together into larger particles, known as flocs.

3. Sedimentation

The water then flows into a sedimentation tank, where the heavy flocs settle at the bottom due to gravity. This process effectively removes a significant amount of suspended solids from the water.

4. Filtration

After sedimentation, the water passes through various filters, typically composed of sand, gravel, and charcoal. These filters remove smaller particles, including microorganisms and residual flocs. Filtration ensures that the water is clear and free from most physical impurities.

5. Disinfection

The filtered water undergoes disinfection to kill any remaining bacteria, viruses, or other pathogens. Chlorination is the most common disinfection method, although alternatives like UV radiation and ozonation are also used. This step is crucial for ensuring the water is microbiologically safe for consumption.

6. Distribution

Finally, the treated water is stored in clean reservoirs and distributed through a network of pipes to households and businesses in Vasant Kunj. Regular monitoring and maintenance of these distribution systems ensure the water remains uncontaminated until it reaches the end users.
