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.

Turbidity means the clarity of water expressed as nephelometric turbidity units (NTU) and measured with a calibrated turbidimeter.

Turbidity means a measure of the clarity or cloudiness of water in Nephelometric Turbidity Units (NTUs). “Two-stage Lime Softening” means a process in which chemical addition and hardness precipitation occur in each of two distinct unit clarification processes in series prior to filtration.

Examples of Turbidity in a sentence

More Definitions of Turbidity

Turbidity means a measure of the cloudiness of water caused by suspended particles. The units of measure for turbidity are nephelometric turbidity units (NTU).

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.

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;

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.

Turbidity means a measure of the clarity or cloudiness of water in Nephelometric Turbidity Units (NTUs).

Turbidity means suspended material such as clay, silt, finely divided organic material, or other inorganic material in water. Turbidity is measured in nephelometric turbidity units (NTU).

Turbidity means the cloudiness in water due to the presence of suspended particles such as clay or silt that may create laboratory analytical difficulties for determining contamination above 15A NCAC 02L.
