What is typically the first stage in the water treatment process?

Coagulation is typically the first stage in the water treatment process because it involves adding chemicals, known as coagulants, to the raw water to remove suspended particles and impurities. During this process, the coagulants react with the particles in the water, causing them to clump together into larger aggregates, known as flocs. This is crucial for the subsequent steps in water treatment because it allows for the removal of these larger particles through sedimentation and filtration, leading to improved water quality.

Understanding coagulation as the initial step highlights its importance in effectively preparing the water for later treatment stages, such as filtration and disinfection. By establishing a solid foundation through coagulation, the entire water treatment process can be enhanced, resulting in cleaner, safer drinking water for the community.
