Upward Velocity:
The upward velocity parameter determines what size of floc particles are removed from the sedimentation tank. Thus in order for our design to be comparable to existing sedimentation tank design V up needs to be the same. V up was set to be 100 m/day. From this we calculated the flow rate through the tank to achieve this V up.
Given that there are no lamella the calculations for this are fairly straight forward.

From this equation the flow rate was determined to be 24 L/min.
