What is the function of filtration in the water treatment process?

• A. To sterilize water
• B. To remove solid particles from water
• C. To adjust pH levels
• D. To add minerals to water

Answer: (B)

Filtration in the water treatment process primarily serves to remove solid particles from water. This is achieved through various methods that allow water to pass through filters designed to capture and retain contaminants such as sediments, silt, clay, and organic matter. By employing physical barriers—such as sand, gravel, or membrane filters—filtration ensures that these solids are effectively separated, resulting in clearer and cleaner water that is safer for consumption and subsequent treatment processes. This function is essential because suspended solids can harbor pathogens and other harmful substances, making removal a critical step in ensuring water quality. While filtration may also aid in the overall treatment process, its primary role is to eliminate unwanted particulates, thus improving the clarity and safety of the water for further treatment or direct use.
