\TUR-bid\, adjective: 1 Muddy; thick with or as if with roiled sediment; not clear; -- used of liquids of any kind 2 Thick; dense; dark; -- used of clouds, air, fog, smoke, etc 3 Disturbed; confused; disordered
Having the lees or sediment disturbed; roiled; muddy; thick; not clear; used of liquids of any kind; as, turbid water; turbid wine
(1) Having the lees or sediment disturbed; roiled; cloudy (2) Not clear or translucent; clouded, muddy; dull; impure; polluted Also see Turbidity ADVANCE \x 540
a measure of the opacity of the atmosphere A perfectly clear sky has a turbidity of 0, and a perfectly opaque sky has a turbidity of 1 Turbidity is affected by air molecules and aerosols
the amount of solid particles that are suspended in water and that cause light rays shining through the water to scatter Thus, turbidity makes the water cloudy or even opaque in extreme cases Turbidity is measured in nephelometric turbidity units (NTU)
Measure of extent to which light passing through water is reduced due to suspended materials (see nephelometric) The optical property of water based on the amount of light reflected by suspended particles Cloudiness of water, measured by how deeply light can penetrate into the water from the surface The cloudy appearance of water caused by the presence of suspended and colloidal matter The scattering and absorption of light that makes the water look murky Caused by the content and shape of matter suspended in the water The state of having sediment or foreign particles suspended or stirred up in water Reclamation partnered with the City of Ft Collins to provide additional water quality monitoring equipment needed, in part, to better detect turbidity at low water levels, particularly during construction
Visible undissolved solid material suspended in water Increasing the turbidity of the water decreases amount of light that penetrates the water column High levels of turbidity are harmful to aquatic life
Turbidity is defined by the American Public Health Association as the "optical property of a water sample that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample," i e the cloudiness or transparency of the water sample
The cloudy condition of the water due to the presence of extremely fine particles in sus- ension that cannot be trapped by the filter because they are too small Adding a clar- ifier, such as an organic polymer or alum, will coagulate the particles and make the filter more efficient
In water bodies, the condition of having suspended particles that reduce the ability of light to penetrate beneath the surface Some rivers and streams are naturally more turbid than others; soil erosion and runoff into streams can increase turbidity
(1) a condition in water or wastewater caused by the presence of suspended matter, resulting in the scattering and absorption of light rays (2) a measure of fine suspended matter in liquids (3) an analytical quantity usually reported in turbidity units (NTU/FNU, FTU, JTU) determined by measurements of light diffraction
a condition that reduces atmospheric transparency to radiation, especially light The degree of cloudiness, or haziness, caused by the presence of aerosols, gases, and dust
A measure of the amount of finely divided suspended matter in water, which causes the scattering and adsorption of light rays Turbidity is usually reported in arbitrary nephalometric turbidity units (NTU) determined by measurements of light scattering NTU should not exceed 0 5 in potable water Turbidity can protect bacteria from sterilization
The cloudy appearance of water caused by the presence of suspended matter A turbidity measurement is used to indicate the clarity of the water A turbidimeter is an instrument that measures the amount of light that is reflected by suspended particles in the sample of water Turbidity has no health effects However, turbidity can interfere with disinfection and provide a medium for microbial growth Turbidity may indicate the presence of disease-causing organisms
A measure of the cloudiness of water, including clay, silt, organic and inorganic matter, algae, and microorganisms High turbidity can cause disinfectants to become ineffective
