What is the purpose of a coagulation aid in water treatment?

• A. To slow down the filtration process
• B. To enhance the coagulation process by improving particle removal efficiency
• C. To eliminate all pathogens
• D. To introduce additional contaminants

Answer: (B)

The purpose of a coagulation aid in water treatment is to enhance the coagulation process by improving particle removal efficiency. Coagulation aids, which can include substances like polymers or certain aluminum salts, work by improving the ability of coagulants to aggregate fine particles and impurities present in water. This is particularly important for smaller particles that may not easily settle or be filtered out during treatment. By optimizing the coagulation process, these aids help form larger, more easily removable flocs, thus increasing the overall effectiveness of the water treatment process. In addition, coagulation aids can facilitate the settling of particles, improve water clarity, and reduce the overall amount of chemicals needed for treatment. Efficient particle removal is crucial in producing high-quality drinking water and ensuring compliance with health and safety standards.
