【Weekly Topic】(Wed**) 2015.8.13 What is turbidity? What are suspended solids? What is the difference between the two?

1. Turbidity refers to the degree of obstruction caused by suspended particles in water to the passage of light. 2. Suspended solids refer to solid substances suspended in water, including insoluble inorganic substances, organic substances, as well as silt, clay, microorganisms, etc. 3. Turbidity indicates the amount of suspended particles in water and is an important indicator of water quality.

Turbidity is a measure of a solution’s ability to scatter light; since water contains suspended and colloidal particles, it becomes turbid, and the degree of this turbidity is referred to as turbidity. It is expressed in degrees. Suspended solids refer to solid substances suspended in water, including water-insoluble inorganic and organic substances as well as sediment and microorganisms. Suspended solids can also be expressed by turbidity. Relationship between the two: 1MG/L = 0.13NTU

Turbidity refers to the degree of obstruction caused by suspended particles in water to the passage of light. Suspended solids refer to solid substances suspended in water, including insoluble inorganic substances, organic substances, as well as sediment, clay, microorganisms, and the like. Generally speaking, the more suspended particles there are in water, the greater the obstruction to light, and thus the higher the turbidity of the water. However, the turbidity of water is related not only to the amount of suspended substances in it, but also to their size, shape, and refractive index. Turbidity is a measure of the degree to which suspended particles in water interfere with the passage of light. In other words, due to the presence of insoluble substances in the water, some of the light passing through the water sample is absorbed or scattered, preventing it from passing through in a straight line. Therefore, turbidity is an optical property of water samples. Suspended solids are particulate matter in water with diameters ranging from 0.4 to 62 micrometers, and they are measured using filtration methods; whereas turbidity is determined by photometric methods, and its concentration is expressed in different units.

Suspended solids refer to solid substances suspended in water, including insoluble inorganic and organic materials as well as sediment, clay, microorganisms, etc. Turbidity is the degree of obstruction caused by these suspended solids to the passage of light through water. Generally, the more suspended solids there are in water, the greater the obstruction to light, and thus the higher the turbidity of the water. However, water turbidity is not only related to the amount of suspended substances in water but also to their size, shape, and refractive index.

What is turbidity? What are suspended solids? What is the difference between the two? Answer: Turbidity—is a measure of the degree to which suspended particles in water interfere with the passage of light. Suspended solids refer to substances that can be retained by a filter. The difference is that turbidity is mainly caused by suspended solids and colloids in water; it is an optical effect of these suspended particles, but turbidity is not equivalent to the sum of suspended solids and colloids. The degree of turbidity is related not only to the amount of suspended particles, but also to their particle size, shape, and the ability of their surfaces to scatter light.

Suspended solids refer to solid substances suspended in water, including insoluble inorganic and organic materials as well as sediment, clay, microorganisms, etc. Turbidity is the degree of obstruction caused by these suspended solids to the passage of light through water. The turbidity of water arises from the presence of particles in suspended or colloidal states, which cause originally colorless and transparent water to become cloudy; the extent of this cloudiness is what is referred to as turbidity. The unit for turbidity is expressed in “degrees”; it corresponds to a turbidity level of 1 degree, or Jackson, when 1 mg of SiO2 (or an equivalent amount of milligrams of kaolin or diatomite) is present in 1 liter of water. Generally speaking, the more suspended particles there are in water, the greater the obstruction to light, and thus the higher the turbidity. However, the turbidity of water is not only related to the amount of suspended particles present, but also to their size, shape, and refractive index.

Turbidity refers to the degree of obstruction caused by suspended particles in water to the passage of light. Suspended particles are solid substances floating in water, including insoluble inorganic substances, organic substances, as well as sediment, clay, microorganisms, and so on. So in general, the more suspended particles there are in water, the greater the obstruction to light, and thus the higher the turbidity of the water. However, the turbidity of water is related not only to the amount of suspended substances in it, but also to their size, shape, and refractive index.
