In a drying bed, the usual depth of the sand layer is?

• A. 2-6 inches
• B. 4-12 inches
• C. 6-10 inches
• D. 8-14 inches

Answer: (B)

The usual depth of the sand layer in a drying bed is typically between 4 to 12 inches. This range allows for effective water drainage and provides sufficient support for the solid waste that is being processed. A sand layer that is too shallow may not adequately filter contaminants, while a layer that is too deep could lead to slower drainage and potential operational issues. The 4 to 12 inches depth strikes a balance, ensuring both optimal drainage characteristics and sufficient capacity to retain and process the sludge moisture effectively. Thus, this range is widely accepted in water treatment practices to ensure efficiency and effectiveness in the drying process.
