Description

Given the water temperature, the flow to be treated, the number, dimensions, and spacing of the modules, their slope relative to the horizontal, and the corresponding Sc coefficient, this calculation determines:

• The flow velocity between the modules.
• The critical sedimentation velocity of the flocs to be removed.
