There are three variations of sedimentation tanks that the demo plant team can use. The purpose of these experiments were to find which sedimentation tank produced the lowest effluent turbidity when ran run at a number of flow rates. The preferred tank will be used in the production of additional demo plants. The tanks are displayed below.

The experimental set up consists of the stock clay solution at 2 .5 g/L mL and a stock alum solution at 1 g/LmL. Two peristaltic pumps controlled by the process controller control the flow of both solutions into the flocculator (the same flocculator is used in each of the three setups). The solution with the flocs then flow into the sedimentation tank and the effluent is moved to a turbidimeter by a third peristaltic pump. The Demo Plant was run with the above tank at flow rates of 50, 100, 150 mL/min.
