These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production haze is defined as the percentage of light that is deflected more than 2.5Â° from the incoming light direction.
Turbidity measurements are often used as an indicator of water quality based on clarity and estimated total suspended solids in water. The turbidity of water is based on the amount of light scattered by particles in the water column 2. The more particles that are present, the more light that will be scattered. As such, turbidity and total suspended solids are related.
