What characterizes the granular media filters used in drinking water treatment?

• A. They require chemical additives for effectiveness
• B. They often consist of mixed media and various configurations
• C. They are primarily used for industrial applications
• D. They are mainly employed for wastewater treatment

Answer: (B)

Granular media filters are key components in the treatment of drinking water, and their effectiveness often comes from their unique design and composition. They typically consist of various materials such as sand, gravel, or other granular substances that can be tailored to optimize the filtration process. The use of mixed media allows for enhanced removal of particles and contaminants, as different materials can capture various sizes and types of impurities more effectively than a single medium could. The diverse configurations of these filters further contribute to their adaptability and effectiveness in treating drinking water. This means they can be designed to suit specific requirements based on factors such as the source water quality, desired flow rates, and treatment goals. Thus, the flexibility and multifunctionality of mixed media granular filters align well with the needs of drinking water treatment processes. In contrast, options that refer to chemical additives, industrial applications, and wastewater treatment do not accurately reflect the primary role or characteristics of granular media filters in the context of drinking water treatment. These filters are specifically designed to improve water quality for safe consumption, making the characterization of mixed media vital for understanding their function.
