Turbidity is one of the most important parameters used to determine the quality of drinking water. Once considered the main aesthetic feature of drinking water, there is clear evidence that controlling turbidity is an effective guarantee for preventing pathogens.
In natural water, turbidity measurement is used to measure general water quality and its compatibility in applications involving aquatic organisms. Monitoring and treatment of wastewater were once entirely based on turbidity control.

At present, it is necessary to measure turbidity at the end of the wastewater treatment process to verify whether these values meet regulatory standards.

The turbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted. The scattering of light through liquids is mainly caused by the presence of suspended solids.
The higher the turbidity, the greater the amount of scattered light. Even very pure liquids will scatter light to a certain extent, as the absence of a solution will result in zero turbidity.

Turbidity is one of the physical indicators of water bodies. It characterizes the degree to which suspended substances in water obstruct the transmission of light. Generally speaking, the more insoluble substances in water, the higher the turbidity. Turbidity is formed due to the presence of particulate matter such as clay, sludge, colloidal particles, plankton, and other microorganisms in water. It is used to indicate the clarity or turbidity of water and is one of the important indicators for measuring the quality of water. Turbidity and chromaticity are both optical properties of water, but they differ. Chromaticity is caused by dissolved substances in water, while turbidity is caused by insoluble substances. Therefore, some water bodies have high chromaticity but are not turbid, and vice versa. GB 5749-2006 "Sanitary Standards for Drinking Water" stipulates a turbidity limit of 1 NTU for drinking water, and 3 NTU for water sources and purification technology conditions. The commonly used method for measuring turbidity is the scattering method. International standards stipulate the use of 90 ° scattered light for measurement.
