A » The surface overflow rate (SOR) measures the flow rate per unit surface area of a sedimentation basin, indicating how effectively particles settle. In contrast, the weir loading rate refers to the flow rate per unit length of a weir, assessing the potential for water to spill over. Both metrics are crucial for optimizing sedimentation and ensuring efficient water purification processes.

A »Surface overflow rate measures the flow rate per unit surface area of a settling tank, while weir loading rate measures the flow rate per unit length of the weir. The former assesses settling efficiency, and the latter evaluates the hydraulic loading on the weir, both crucial in water purification processes.
