What is the maximum filtration rate for gravity rapid sand filters?

• A. 4.0 gpm/sq ft
• B. 1.0 gpm/sq ft
• C. 2.0 gpm/sq ft
• D. 3.0 gpm/sq ft

Answer: (C)

The maximum filtration rate for gravity rapid sand filters is typically around 2.0 gallons per minute per square foot (gpm/sq ft). This rate is significant because it balances effective removal of particulates from the water while maintaining high operational efficiency. Exceeding this filtration rate could lead to an inadequate treatment process, as the water passes through the filter media too quickly, compromising the ability to remove contaminants effectively. In terms of practical application, operating within this maximum filtration rate allows for optimal performance of the filter system, ensuring that water is treated properly before it is distributed for use. Factors such as the type of media, design of the filter, and the quality of the incoming water can influence the filtration rate, but 2.0 gpm/sq ft serves as a standard guideline in most practices related to gravity rapid sand filtration.
