The first step in the flocculator design is to choose whether to use horizontal or vertical flocculation. This is largely dependent on the flow rate and depth. The following steps are taken to determine which one to use.
Determine the height of water at the end of the flocculation tank. The user has three options: Minimum depth for horizontal flow, same as depth in sedimentation tank, or a user specified value.
Set the J/S value equal to 3 (this is the optimal value and will be used for horizontal flocculation). Set S to it's minimum value of 45 cm (minimum for a human to walk through for maintenance).
