Turbidity: Measurement of Filtrate and Supernatant .
1/1/2015· Originally, turbidity was a parameter used in limnological work to study the depth at which light can penetrate a body of water. Field measurements still use the Secchi disk, shown in Figure 1.The disk is lowered in the water until it becomes obscure. Figure 2 shows a relationship between Secchi disk readings and standard turbidity readings (see also Davies-Colley, 1988).

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' (fig1-'B'), uses a sensing weight which is lowered on a measuring tape into the thickener to detect the bed level.
