How Is Water Cleaned at a Water Treatment Plant?

During filtration, the clear water passes through filters that have different pore sizes and are made of different materials (such as sand, gravel, and charcoal). These filters remove dissolved particles and germs, such as dust, chemicals, parasites, bacteria, and viruses.

How Is Water Cleaned at a Water Treatment Plant?

Water treatment plants play an important role in ensuring that the water we drink is clean and safe. Water is treated in a variety of ways in order to remove contaminants and make it suitable for drinking. The process of cleaning water at a water treatment plant begins with the physical separation of particles, which can include gravel, sand, and other debris. This process is known as screening or straining.

Once the physical separation is complete, the water is then sent through a series of chemical treatments. These treatments involve adding chemicals such as chlorine, sodium hydroxide, and alum to the water. These chemicals help to remove bacteria and other contaminants from the water.

The next step in the water treatment process is known as sedimentation. During sedimentation, particles in the water settle out and the water is then sent through filters. The type of filter used depends on the type of particles that are being removed from the water. For example, sand filters are used to remove sand and other large particles, while activated carbon filters remove smaller particles.

Once the water has been filtered, it is then disinfected. This is done by adding chlorine or another disinfectant to the water. This kills any remaining bacteria and other microorganisms that may be present in the water
