What is the main objective of chemical precipitation in water treatment?

• A. To remove dissolved contaminants by forming solid particles
• B. To enhance the taste of water
• C. To increase water temperature
• D. To add nutrients to the water

Answer: (A)

The main objective of chemical precipitation in water treatment is to remove dissolved contaminants by forming solid particles. This process involves adding certain chemicals to the water, which react with the dissolved substances to create solid particles that can be easily separated from the liquid. These solid particles, known as precipitates, are then removed through processes such as sedimentation or filtration. Chemical precipitation is particularly effective for removing various ions, such as heavy metals or phosphorus, that can be harmful to human health and the environment. By converting these dissolved contaminants into solid forms, the process enhances the overall quality of the water, making it safer for consumption and use.
