What role does a coagulant play in water treatment?

• A. It adds nutrients to the water
• B. It helps to destabilize and aggregate pollutants for easier removal
• C. It enhances the taste of the water
• D. It cools the water during treatment

Answer: (B)

In water treatment processes, the coagulant serves a crucial function by helping to destabilize and aggregate suspended particles and pollutants present in the water. When added to the water, the coagulant interacts with these particles, neutralizing their charge and causing them to clump together, or coagulate. This aggregation makes it easier to remove the pollutants from the water during subsequent filtration or sedimentation processes. By effectively enhancing the removal of particulates, coagulants improve the overall clarity and quality of the water, which is essential for meeting regulatory standards and ensuring safe drinking water. The ability of coagulants to aid in the aggregation process is fundamental in achieving efficient water treatment, making this role indispensable in the overall operation of water treatment facilities. Other options do not accurately represent the function of a coagulant; for instance, adding nutrients, enhancing taste, or cooling the water are not functions typically associated with the coagulation process in water treatment.
