Goal: Determine if lamella decrease turbidity significantly, and determine the height of the floc blanket at which the turdibity is lowest in both tanks.
Procedure:
Upon formation of a floc blanket in each tank, the tanks will be drained slowly to bring the tops of the blankets to the same level in the two tanks. We will begin with the blanket at a height such that it's top is about halfway through the lamella. Turbidity data will be collected from each tank. Then the blanket will be lowered incrementally and more data collected.
