If the return water to the process has high suspended solids loading, then it can affect the performance of the plant. In most cases settling the Thickener, under these conditions, requires the process plant to reduce production, which will decrease the water flow to the Thickener and in turn, increase the retention rate within the Thickener.

This measurement is targeted at turbidity profiling as well as bed-level detection. If only bed-level measurement is required, then the buoyancy principle is more cost effective. The 'buoyancy based electromechanical system' (Figure1-'B') uses a sensing weight which is lowered on a measuring tape into the thickener to detect the bed level.

Control Strategies for thickeners

A bed/mud level target is used to obtain optimum loading in the thickener without overloading the drive mechanism. Bed pressure is used as an indication of solids inventory. This helps the system determine whether a high bed level is the result of decreased settling rate or increased solids inventory.
