Interpretation: Turbidity can be understood as the cleanliness of the transparent medium. It is caused by tiny particles such as silt, clay, microorganisms and organic matter. The scattering and absorption of incident light by suspended matter causes light attenuation. The change of turbidity is usually to measure the intensity of scattered light, the intensity of […]
