Turbidity definition

Turbidity means the cloudy condition of water due to the presence of extremely fine particulate materials in suspension that interfere with the passage of light.

More Definitions of Turbidity

Turbidity means an expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through a water sample; turbidity in water is caused by the presence of suspended matter such as clay, silt, finely divided organic and inorganic matter, plankton, and other microscopic organisms;
Sample 1Sample 2Sample 3
Turbidity means the cloudiness in water, due to the presence of suspended particles such as clay and silt that may create esthetic problems or analytical difficulties for determining contamination. Turbidity, measured in Nephelometric Turbidity Units (NTU), is based on a comparison of the cloudiness in the water with that in a specially prepared standard.
Sample 1Sample 2Sample 3
Turbidity means the optical condition of waters caused by suspended or dissolved particles or colloids that scatter and absorb light rays instead of transmitting light in straight lines through the water column. Turbidity may be expressed as nephelometric turbidity units (NTU) measured with a calibrated turbidimeter.
