Which processes are included in the process of coagulation?

The processes involved in coagulation encompass a variety of reactions and mechanisms that facilitate the removal of suspended particles from water. Coagulation primarily aims to destabilize colloidal particles, allowing them to clump together and subsequently be removed through sedimentation or filtration. This process does indeed involve a combination of chemical reactions, such as those that occur when coagulants like alum or ferric chloride are added to the water. These coagulants work by neutralizing the charges on particles, facilitating their agglomeration.

Additionally, coagulation also requires physical processes, such as mixing to ensure the coagulants are evenly distributed and to promote particle collisions that lead to agglomeration. Thus, the comprehensive view of coagulation includes various types of reactions and mechanisms working together—both chemical and physical—to effectively treat water. This multifaceted approach is crucial for optimizing water quality in treatment facilities.
